The official, static-linked linux builds were crashing in their use of
getaddrinfo, which libcurl was configured to use. Both getaddrinfo
and all of its alternatives available in glibc fail with static
linking.
We can fix this by configuring libcurl to use libc-ares on Linux
instead. This allows us to keep the benefits of a statically-linked
Linux binary.

The script in packager/testing/dockers/test_dockers.sh now outputs
more useful info for debugging, uses unique container names per OS so
that the containers can be debugged, and allows filtering to re-run
specific OSes if a build fails.

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.

## 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
It was suggested in code review for another project that we update the
runner labels for clarity. This brings Packager in line with that, so
that we are using the same labels across projects.
The runners have already been updated to register with the new label.

Now that we have multiple architectures, we should factor both OS and
architecture into the names of release binaries. This makes the names
more formulaic, as well as consistent with the static-ffmpeg-binaries
repository. Shaka Streamer will pull binaries from both this repo and
that one, so consistent names would be helpful.
The pssh-box release is actually OS and architecture independent, so
remove the suffix from that and only release one copy of it.

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.

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.

When using CC=clang CXX=clang++, there is a binutils version check

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
There is not a good reason to use a long-lived token attached to
shaka-bot. Instead, use a short-lived, automatic token generated by
GitHub Actions for the workflow run.
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 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:

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.

Testing CI workflows is a pain. This usually involves forking the
main repo and testing various operations there, where the results will
not break the main repo.
However, some things like NPM and Docker package names were initially
hard-coded. This meant that a fork would need to customize those in
the workflows to avoid pushing official-looking packages during CI
testing.
This change moves those hard-coded names to GitHub Secrets. Though
the names are not actually secret, the secret store is per-repo, and
will be independent in a fork. This makes it easier to avoid
accidentally pushing official-looking releases during testing, even if
the fork has access to the same auth tokens.

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.

- Exports the File class used by packager.exe
- Removes the explicit File dependency in packager.exe in favor of

We do not use clang to build on Windows, so we should skip trying to
update clang. This is critical to MSVS 2019 support, since the older
clang tools we depend on do not recognize that newer environment.
Since we don't need clang anyway, skipping the update avoids useless
errors about finding a matching clang version for the environment.

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.
