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.

This fixes the Debug build of libpng on arm64 by avoiding CPU-specific
optimizations that are not in our sources list. The Release build
appears to have been unaffected, possibly due to link-time
optimizations or dead code stripping.

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

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.

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.

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

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.

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.

To make shared_library builds work on Windows with MSVS 2019, this
commit:
- Silences a useless warning about a private member in dll-exported
Status class.
- Exports the File class used by packager.exe
- Removes the explicit File dependency in packager.exe in favor of
libpackager, now that File is exported
- Add missing defines in packager.exe and packager_test.exe that
instruct the linker to import Status and File from the library

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>.
At this point static_library builds are working in MSVS 2019.
shared_library builds are still not working.

Legacy players, e.g. older versions of ExoPlayer, do not handle default webvtt text alignment correctly. Need to specify `align:center` explicitly cues without text alignment for backwards compatibility.
Fixes#925.
- Do not write the HTTP PUT response to cache which can potentially overflow the cache buffer as it is not consumed.
- VLOG(1) instead of LOG(ERROR) on HttpFile::Size() as it can be called during normal code execution.
- Add a command line flag `--user_agent` to allow users to specify their custom user agent string.

This also allows setting the language of different text streams from
the same input. Multiple streams can use the same input stream
using different cc_index values and can each use a different language.
This also will try to pull the language from the input if not
specified.

Note that this only supports a single page within the DVB-sub stream.
Multiple pages will be merged together. A follow-up will allow
selecting a specific page.
This only supports outputting using TTML or MP4+TTML; you cannot have
DVB-sub output nor can you output it in WebVTT. Since DVB-sub
uses images, it is hard to impossible to do this with WebVTT.
This also only supports interlaced images, not progressive images
nor text.
