Joey Parrish 0afda1725c test: Update Dockerfiles
This updates the main Dockerfile and all the docker-based
distro-specific tests.  The base OS versions have been updated to
versions that have not reached end-of-life status yet, and the list of
dependencies required has been updated and pruned.

Joey Parrish efbca399c0 fix: Add missing limits header
In many places, we used std::numeric_limits without including the
proper header.  This would build on some Linux distributions, but not
others.

This adds the missing includes, fixing the build on Fedora, among
other distros.

Joey Parrish 7392d8003e fix: Fix failure fetching encryption keys
In one of the low-latency changes, a change was made to HttpFile that
caused responses to HTTP POST requests to go missing.  This resulted
in failures to fetch encryption keys.

The breaking change was recommended by me in a PR review, and was not
caught by any unit tests.  New tests would be ideal, but I chose to
fix the bug first, rather than leave the repo broken.

This bug was brought to my attention in google/shaka-streamer#87 and
has not appeared in any release versions.

Fix for gap size warning in Low Latency mode (#985)
## The issue
- With LL-DASH mode enabled, the gap size warning was hit and printed to the console every time a new segment was registered to the manifest.
- This occurred because the first chunk's size and duration were being stored for each segment, rather than the full segment size and duration. Note, only the first chunk's metrics are known at first because in low latency mode, the segment is registered to the manifest before it is finished being processed and written.
- Because of this, the gap size check was comparing the end time of the first chunk in the previous segment to the beginning time of the current segment, causing the check to fail every time.

## The Fix
- Update a low latency segment's duration and size once the segment file has been fully written.
- The full segment size and duration will be used to update the bandwidth estimator and the segment info list. 
- Updating the segment info list to hold the full duration is necessary for satisfying [the gap size check found in Represenation.cc](https://github.com/google/shaka-packager/blob/master/packager/mpd/base/representation.cc#L391).
- NOTE: bandwidth estimation is currently only used in HLS

Joey Parrish 249c83f14b build: Fix additional python2/3 issues
The generate_version_string script was only producing correct results
in python 2, not python 3.  The gyp file that references it explicitly
runs it in python3.  The shebang line of the script has been updated
to match.  The script itself has been updated such that it now works
correctly in both python2 and python3.

Scripts that are only used as modules (not executed directly) have had
their shebang lines removed.

This fixes CI failures on GitHub Actions.

Joey Parrish ac125564b9 build: Fix pylint 2.10 issues, use python3 where possible
The newest pylint release complained about several issues that the
older release did not.  This resolves those issues:

 - removes unneeded "u" prefix from strings
 - adds "encoding" parameter for all open() calls
 - because "encoding" is a python3-only parameter, use python3 in all
   the scripts that we control

Unfortunately, python2 is required for any scripts that import modules
from the ancient Chromium build system we're using (referenced by
DEPS), as well as kokoro scripts.

ci: Produce static release executables on Linux (#978)
We never produced static release executables on Linux before, but the dynamic libraries they depended on were universal enough that nobody noticed. Now that we have released v2.5 and switched to GitHub Actions for CI builds, the Linux executables depend on libatomic, which is causing issues for some users.

Although we can't create fully-static executables on macOS or Windows, we can at least do so on Linux.

This adds a GYP variable static_link_binaries which can be set to request full-static binaries on Linux. This also exposes the Chromium build variable disable_fatal_linker_warnings, which is necessary when static linking on Linux due to static-link-related warnings generated by libcurl for its use of getaddrinfo. Finally, this enforces the definition of __UCLIBC__ with static linking on Linux, which is the only way to disable malloc hooks in Chromium base. Those hooks cause linker failures when linking statically on Linux.

A new check has been added to the release workflow to ensure that the builds we create are statically linked on Linux.

Closes #965

Joey Parrish cfbe5c08c2 cleanup: Convert all time parameters to signed
This converts all time parameters to signed, finishing a cleanup that
was started in 2018 in b4256bf0.  This changes the type of:
  - timestamps
    - PTS specifically
  - timestamp offsets
  - timescales
  - durations

This excludes:
  - MP4 box definitions
  - DTS specifically

This is meant to address signed/unsigned conversion issues on arm64
that caused some test cases to fail.

Joey Parrish 68b50f656d build: Stop using hermetic clang, libc++, etc
This brings our default build config more in line with what is
necessary for some platforms anyway: using the system-installed
toolchain and sysroot to build everything.

We will no longer fetch source or binaries for any specific build
tools, such as libc++, clang, gold, binutils, or valgrind.

The main part of this change is the changing of default gyp settings
in gyp_packager.py.  For this, a bug in gyp_packager.py had to be
fixed, in which similar GYP_DEFINE key names (such as clang and
host_clang) would conflict, causing some defaults not to be installed
properly.

In order to enable clang=0 by default, some changes had to be made in
common.gypi:
  - compiler macros added to fix a compatibility issue between
    Chromium's base/mac/ folder and the actual OSX SDK
	- replaced clang_warning_flags variables with standard cflags
	  settings, plus xcode_settings for OSX
  - turned off warnings-as-errors for non-shaka code, rather than
		allow-listing specific warning types, since we can't actually fix
    those warnings on any platform
  - disabled two specific warnings in shaka code, both of which are
    caused by headers from our non-shaka dependencies

Also, one warning (missing "override" keyword) has been fixed in
vod_media_info_dump_muxer_listener.h.

Although these changes were done to make building simpler on a wider
array of platforms (arm64, for example), it seems to make the build a
bit faster, too.  For me, at least, on my main Linux workstation:
  - "gclient sync" now runs 20-30% faster
  - "ninja -C out/Release" now runs 5-13% faster

The following environment variables are no longer required:
  - DEPOT_TOOLS_WIN_TOOLCHAIN
  - MACOSX_DEPLOYMENT_TARGET
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.

The following GYP_DEFINES are no longer required for anyone:
  - clang=0
  - host_clang=0
  - clang_xcode=1
  - use_allocator=none
  - use_experimental_allocator_shim=0
Documentation, Dockerfiles, and GitHub Actions workflows have been
updated to reflect this.

The following repos are no longer dependencies in gclient:
  - binutils
  - clang
  - gold
  - libc++
  - libc++abi
  - valgrind

The following gclient hooks have been removed:
  - clang
  - mac_toolchain
  - sysroot

Joey Parrish 56e227267c Fix python linter errors and add linter checks to CI
Internal CI systems and the new GitHub CI system were out of sync,
with the external system not doing any linting.  Further, the internal
system was using an internal-only linter for Python.

This creates a script for Python linting based on the open-source
pylint tool, checks in the Google Style Guide's pylintrc file, creates
a custom action for linting and adds it to the existing workflows,
fixes pre-existing linter errors in Python scripts, and updates pylint
overrides.

Joey Parrish a2e07a901e Refactor actions and workflows
It turns out that workflows were the wrong way to abstract reusable
pieces of work.  This turns common steps into custom actions (build
docs, build packager, test packager) which can be used as encapsulated
steps in multiple workflows.

This is a much more natural way to avoid duplication compared to the
previous approach of triggering one workflow from another.  This also
has the benefit of all of the steps of a release being represented on
GitHub as a single workflow, making it easier to understand what is
happening and what event triggered those steps.

Joey Parrish 0f8749a211 CI overhaul based on GitHub Actions
This replaces Travis (for Linux & Mac) and Appveyor (for Windows) with
GitHub Actions.  In addition to using GitHub Actions to test PRs, this
also expands the automation of releases so that the only manual steps
are:

 1. Create a new CHANGELOG.md entry
 2. Create a release tag

Workflows have been create for building and testing PRs and releases,
for publishing releases to GitHub, NPM, and Docker Hub, and for
updating documentation on GitHub Pages.

When a new PR is created, GitHub Actions will:
 - Build and test on all combinations of OS, release type, and library
   type

Appveyor's workflow took ~2 hours, whereas the new GitHub Actions
workflow takes ~30 minutes.

When a new release tag is created, GitHub Actions will:
 - Create a draft release on GitHub
 - Extract release notes from CHANGELOG.md & attach them to the
   draft release
 - Build and test on all combinations of OS, release type, and library
   type, aborting if any build or test fails
 - Attach release artifacts to the draft release, aborting if any
   one artifact can't be prepared
 - Fully publish the draft release on GitHub
 - Publish the same release to NPM (triggered by GitHub release)
 - Publish the same release to Docker Hub (triggered by GitHub release)
 - Update the docs on GitHub pages

Joey Parrish 032cf2a345 Fix libpackager_type variable undefined by default
In e2efb5d4, I fixed shared_library builds on Windows, but I
introduced another issue in which the libpackager_type variable was
not correctly defined by default.  This meant that the build only
worked with this variable explicitly-defined in GYP_DEFINES when
gclient sync was run.

This fixes the default definition so that libpackager_type does not
need to be defined explicity.

Joey Parrish 098f58a143 Fix shared library test runs on Windows
Shared library builds worked, but failed tests because they were made
with the wrong CRT linker settings.  Strings allocated within the
library could not be freed outside the library because the dynamic CRT
was not used.

This sets necessary gyp variables to link with a dynamic CRT on
Windows, thereby fixing tests running in shared library mode that
otherwise hung in a GitHub Actions environment.

Joey Parrish ae89145015 Fix vector+unique_ptr issues with MSVS 2019
Because a StreamState object contains a unique_ptr, it is not
copyable.  A vector of StreamStates, therefore, causes a compile error
on resize or push_back, both of which invoke the copy constructor.

I don't know why MSVS complains, but clang does not.

To fix this, I'm changing vector<StreamState> into deque<StreamState>.

KongQun Yang 516430bde1 [MP4] Truncate segment references in 'sidx' if necessary
The reference count in 'sidx' box is a uint16 field, which allows at
most 0xFFFF entries, i.e. at most 0xFFFF subsegments, which is roughly
18 hours for one second segments.

Do not fail packaging when it happens. Instead, generate a warning and
truncate the number of references to 0xFFFF instead.

Note that the actual number of mp4 fragments in the mp4 file can still
be more than 0xFFFF. The stream will not play to the end in DASH, but
it will play successfully in HLS.

Workarounds #862.

for already ref-counted types, and (b) don't pass PID since the

This changes the default MP4 output to use TTML and adds a way to
choose which one is used.  This is done with 'format=ttml+mp4' or
'format=vtt+mp4'.

This also fixes the boxes output in WebVTT in MP4.

This only supports TTML output; meaning the user can convert WebVTT
into TTML, but not the other way around.  This will be useful for
DVB-sub subtitles that would be better supported within TTML.

This only adds text-based output; a follow-up will add MP4 support.

Jacob Trimble 8e85862bda Ignore unsupported H26x streams.
This adds a new path when parsing MPEG2-TS streams to ignore unsupported
streams.  This allows extracting supported streams when some of the
streams are unsupported.  For example, you can extract audio from a
file that has unsupported video.

Jacob Trimble 1f21cc78cd Add style support for cue fragments.
Now text cues are composed of nested fragments that can be individually
styled.  This allows portions of the cue to be bold, etc.  The
WebVTT parser doesn't parse the inputs, but the original tags are
preserved in WebVTT output.  The WebVTT output will add tags if the
style elements are present in the cue object.

making the major changes needed to add that feature.

Jacob Trimble b2220eb0c6 Add text fragment and setting types.
This sets the groundwork for more generic text cues by having a more
generic object for the settings and the body.  This also changes the
TextSample to be immutable and accepts the fields in the constructor
instead of using setters.

Jacob Trimble 56908a83a7 Convert text WebVTT output to muxer.
Now text-based WebVTT also uses the generic media pipeline.  This
converts the WebVttTextOutputHandler to a WebVttMuxer to be more
consistent with the other muxer types.

This also allows choosing between single-segment text and multi-segment.
Before, we would generate both and use single-segment for DASH and
multi-segment for HLS; but now you can choose between either and either
are supported in both DASH and HLS.

Jacob Trimble 2909ca0c77 Handle segmented text same as audio/video.
Now the same pipeline for handling the audio/videos streams will handle
the segmented text streams too.  This doesn't apply to the text output,
only to the MP4 variants.  This also fixes a bug where we added the
X-TIMESTAMP-MAP tag even when there wasn't TS streams; this doesn't
otherwise change the behavior around that tag.
