When uploading a live stream, if a single segment upload fails, we shouldn't give up.
This adds an option to ignore HTTP output failures so that a single failed upload does not result in a hung stream. See https://github.com/shaka-project/shaka-streamer/issues/195 for details.
Upgrading curl fixes errors like "Failed sending data to the peer" flooding the log. This is described upstream in https://github.com/curl/curl/issues/10591 and fixed in curl 8.2.0. Here we upgrade to curl 8.9.1 (latest as of today).
This required updating the way we attach c-ares to libcurl and updating CURLOPT_PUT (deprecated) to CURLOPT_UPLOAD (compatible equivalent AFAICT).
In some cases it can happen that the http server responds with a
non-successful status code without reading the response body. In this
case curl may decide not to read from the cache since there is really no
point in sending data to the server. In case some other thread of shaka
has already called HttpFile::Flush it may end up deadlocked there
waiting for the cache to either close or become empty. Thus, we close
the cache when leaving the main thread as no data will be read by curl
after it has finished anyways.
Closes#1347
This work was done over ~80 individual commits in the `cmake` branch,
which are now being merged back into `main`. As a roll-up commit, it is
too big to be reviewable, but each change was reviewed individually in
context of the `cmake` branch. After this, the `cmake` branch will be
renamed `cmake-porting-history` and preserved.

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.
Fixes#1196
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.

# LL-DASH Support
These changes add support for LL-DASH streaming.
**NOTE:** LL-HLS support is still in progress, but it's coming. :)
## Testing
`./chunking_unittest --gtest_filter="ChunkingHandlerTest.LowLatencyDash"`
`./media_event_unittest --gtest_filter="MpdNotifyMuxerListenerTest.LowLatencyDash"`
`./mpd_unittest --gtest_filter="PeriodTest.LowLatencyDashMpdGetXml"`
`./mpd_unittest --gtest_filter="SimpleMpdNotifierTest.NotifyAvailabilityTimeOffset"`
`./mpd_unittest --gtest_filter="SimpleMpdNotifierTest.NotifySegmentDuration"`
`./mpd_unittest --gtest_filter="LowLatencySegmentTest.LowLatencySegmentTemplate"`
Note, packager_test must be run from the main project directory
`./out/Release/packager_test --gtest_filter="PackagerTest.LowLatencyDashEnabledAndUtcTimingNotSet"`
`./out/Release/packager_test --gtest_filter="PackagerTest.LowLatencyDashEnabledAndUtcTimingNotSet"`
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.

- 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.
Fixes#939.
