As per the AV1 spec, the codec string may contain optional color values.
This extracts the missing color information from the mp4 `colr` atom, if
present, and generates the full AV1 codec string.

Closing the upstream on flush will effectively terminate the ongoing
curl connection. This means that we would need re-establish the
connection in order to resume writing, this is not what we want. In the
spirit of the documentation of File::Flush
```c++
/// Flush the file so that recently written data will survive an
/// application crash (but not necessarily an OS crash). For
/// instance, in LocalFile the data is flushed into the OS but not
/// necessarily to disk.
```
We will instead wait for the curl thread to finish consuming what ever
might be in the upload cache, but leave the connection open for
subsequent writes.

# Low Latency DASH - `availabilityTimeComplete=false`
Low Latency DASH manifests generated by Packager were missing the
attribute `availabilityTimeComplete`. As per the [DASH
specs](https://dashif.org/docs/CR-Low-Latency-Live-r8.pdf):
**_the AdaptationSet@availabilityTimeCompleteshould be present and be
set to 'FALSE'_**
## The Issue
The missing attribute caused ULL streams from Shaka Packager to no
longer be compatible with DASH.js. Previous versions of DASH.js allowed
users to specify ULL mode when initializing the player. However, the
most recent releases of DASH.js automatically detect ULL by scanning the
manifest for ULL specific attributes. Although there are many attributes
only associated with ULL, [DASH.js only greps for
`availabilityTimeComplete` in its detection
logic](https://github.com/Dash-Industry-Forum/dash.js/blob/development/src/streaming/controllers/PlaybackController.js#L792-L805).
Because of the missing attribute in Packager and the limited ULL
verification criteria by DASH.js, Packager streams were not being
treated as low latency streams by DASH.js.
## Testing
### Unit Testing
`./mpd_unittest
--gtest_filter="SegmentTemplateTest.OneSegmentLowLatency"`
` ./mpd_unittest
--gtest_filter="LowLatencySegmentTest.LowLatencySegmentTemplate"`
### Manual Testing
- Created a low latency stream with Shaka Packager
- Observed the expected `availabilityTimeComplete=false` attribute in
the generated DASH manifest.
It appears that not all Apple implementations follow the HLS guidelines.
While the DEFAULT=NO for an audio track should be optional and default
to NO, in practice native HLS players Safari and iOS devices treat the
missing DEFAULT as a MAYBE.

This issue is observed on Python 3.10+ and above.
This workaround addresses a major backwards compatibility break with a

A single-line change on #L170 to `wv.protection_scheme =
struct.unpack('>L', bytes(protection_scheme, encoding='utf-8'))[0]`,
needed to work around this issue on Ubuntu 22.04LTS+ running Python
3.10+:
```sh
TypeError: a bytes-like object is required, not 'str'
```
On line 170.
This brings some workflow improvements and fixes from the `cmake` branch
to `main`, as well as some unique fixes to keep gclient working, so that
we can continue to accept contributions in `main` until the `cmake`
merge is ready.
- Fix docs build in GitHub Actions (from `cmake` branch)
- Cancel workflow when a PR is updated (from `cmake` branch)
- Fix docker failures caused by running as root (from `cmake` branch)
- Work around exception in depot_tools on Windows
- Use Windows 2019 images in GitHub Actions for compatibility with gyp
- Remove Docker build on ArchLinux, which no longer supports python2 at
all
- (NOTE: The `cmake` branch is still building on ArchLinux. Docker
builds for Arch will be restored to the `main` branch when the `cmake`
branch is finally merged to `main`.)

Note:
* An xHE-AAC capable encoder will auto adjust the user-specified SAP/RAP
value to the allowed grid where SAP/RAPs can occur.
e.g.: `-rapInterval 5000` (5s) may result in actual SAPs/RAPs every
4.984s.
* To ensure SAP/RAP starts a new segment, Shaka needs to executed with a
"--segment_duration" is less than or equal to that adjusted value.
* If every SAP/RAP should trigger a new segment, just set the segment
length to a very low value e.g.: `--segment_duration 0.1`
Using the latest depot_tools no longer works. depot_tools also wants
to auto-update itself, which must now be disabled.
We also need to disable the copy of python (vpython) included in
depot_tools, since for some distros, it has dependencies on system
libraries that no longer exist.
Finally, we need to force some distros to use python 2, because our
build system is ancient and needs to be ripped out and replaced some
day soon.
This fixes build issues in our CI, our Dockerfiles, and in general on
certain platforms or distros.

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.

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.

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.

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.
