style: Sort headers to comply with the style guide (#1273)
Reorder headers to follow the Google C++ Style Guide:

> In dir/foo.cc or dir/foo_test.cc:
>
> 1. dir2/foo2.h.
> 2. A blank line
> 3. C system headers (more precisely: headers in angle brackets with
the .h extension), e.g., <unistd.h>, <stdlib.h>.
> 4. A blank line
> 5. C++ standard library headers (without file extension), e.g.,
<algorithm>, <cstddef>.
> 6. A blank line
> 7. Other libraries' .h files.
> 8. A blank line
> 9. Your project's .h files.

style: Use angle-brackets for all internal headers (#1271)
This feeds into efforts to create a working install target.

The order of headers is still funky, and was "fixed" by clang-format,
but in a way that doesn't exactly align with the style guide. Further
cleanup of header order is coming in a follow-up PR.

test: Avoid crashing a test executable (#1242)
LOG(FATAL) aborts the executable, which means gtest can't write any
reports it might be configured to write when tests are complete. This
will interfere with reporting.

This converts the only use of LOG(FATAL), which was in
ReadTestDataFile(), to LOG(ERROR). This also updates test cases to avoid
crashing when ReadTestDataFile() returns an empty buffer.

feat: port media/base (#1127)
This removes all chromium dependencies from media/base/ and completes
the build system in CMake.

The ClosureThread class and its classes were removed, as they were
specific to chromium base. ClosureThread has been replaced by
std::thread.

The byte-swapping utilities in network_util.cc have been removed and
replaced with absl.

generate_unique_temp_path() was split out of file_unittest.cc into
file_test_util.cc, where other test suites could make use of it.

WARN_UNUSED_RESULT was replaced with the C++ standard attribute
[[nodiscard]].

The base::Clock interface was replaced with a typedef for a function
pointer that returns the current time.

This re-enables the tests in http_key_fetcher_unittest.cc by using
httpbin.org.

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.

In addition to the MediaSample handling of the MediaParser, this now
adds callbacks for TextSample.  This allows reading text streams from
the media files.

KongQun Yang d850befb72 Refactor and Cleanup Descriptor classes
- Define BaseDescriptor and generic read / write operations.

- Define descriptors: ESDescriptor, DecoderConfigDescriptor,
  DecoderSpecificInfoDescriptor, SLConfigDescriptor.
  DecoderSpecificInfoDescriptor and all other descriptors can now
  handle arbitrary length size, not limiting to 64 byte for
  DecoderSpecificInfoDescriptor, which was placed to limit
  ESDescriptor length size to one byte.

- Now DecoderConfigDescriptor is able to handle reading and writing
  of all fields including buffer_size_db, which was not handled
  earlier.

Fixes #536.

KongQun Yang 8e96dd3b37 Address gcc build failures in some platforms
Seeing some failures on some platforms when compiled with clang
disabled:
  GYP_DEFINES="clang=0" gclient runhooks

Several changes to make it work:
1. Mark packager code with packager_code=1 in GYP definitions.
2. Disable a few checks in non-packager code, which we do not have
   direct control: dangling-else, deprecated-declarations,
                   unused-function
3. Fix the relevant errors in packager code.
4. Revert HAVE_STROPTS_H in curl config which is not available in
   all linux distributions.

KongQun Yang 92e1e39868 Update MediaSample to avoid redundent copying
Use std::shared_ptr<const uint8_t> with a custom deleter to
represent MediaSample::data_ instead of std::vector<uint8_t>.

MediaSample::data_ can be shared by multiple MediaSamples and it is
immutable. A new data instance must be created if the clients want to
modify the underlying data. The new data instance can be transferred
to MediaSample using provided MediaSample::TransferData function.
This avoids unnecessary data copying.

Kongqun Yang 277c5b23c0 Allow generating avc3 / hev1 from TS and Wvm files
Added a flag --strip_parameter_set_nalus. When enabled, parameter
set NAL units, SPS/PPS for H264 and SPS/PPS/VPS for H265, are stripped
from frames when converting NAL byte stream (AnnexB stream) to NAL
unit stream, which generates avc1/hvc1; otherwise they are not
stripped, and avc3/hev1 is generated.

Parameter set NAL units should not be stripped if they are varying
in the frames otherwise the frames may fail to be decoded.

The flag is enabled by default as we don't usually see varying
SPS/PPS/VPS and it is more space efficient with them stripped.

Set --strip_parameter_set_nalus=false to disable the flag if there
are varying SPS/PPS/VPS in the frames. This addresses #206.
