chore: Refactor public headers and macros (#1275)
This organizes all public headers for the library into
include/  and makes sure then don't rely on any headers from
other folders.

To accomplish this, this change also refactors macros.h,
media/base/macros.h, and status/status_macros.h into macros/classes.h,
macros/compiler.h, macros/crypto.h, macros/logging.h, macros/status.h,
and public/export.h.  Now the export macros from macros.h live in
include/ to keep include/ from requiring anything else.

This refactor enables an install target that includes public headers
only.

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.

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 ClosureThread has been replaced by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.

Jacob Trimble 7e41937bb1 Consolidate key system enums.
There were several enum types that all were used for key systems.  This
combines them into one to make it more clear and only needing to update
one.  This also uses a bit field to specify multiple key systems instead
of using a std::vector.

srebrnyp 22af5533b1 Add crypto_period_seconds to Widevine key request (#545)
Add crypto_period_seconds to Widevine key request

When using key rotation with Widevine DRM, a key server has to know
the duration of crypto period to relate generated keys to the media
playback time. This helps the server to provide relevant keys to
a client during license request.

Closes #544.

KongQun Yang ae82cd16f3 Remove the usage of JsonWriter in WidevineKeySource
Uses protobuf JSON util instead.

packager/base/json_writer comes from Chromium base. We are going to
replace it with abseil, which does not have a JSON library.

The code is much more cleaner now.

This is unfortunately, at the expense of increased output binary size.
packager binary increases by another 100KB.

Jacob Trimble d5cdd00ba1 Move fixed key encryption code to new FixedKeySource.
KeySource is now an abstract class that is implemented in two
types WidevineKeySource and FixedKeySource.  This also updates
fixed key encryption to use v1 PSSH boxes with the common system
ID.

This also updates the --pssh argument.  Now it accepts full PSSH
boxes rather than data.  Multiple PSSH boxes can be concatenated
together.

Changed the one using PSSH data in favor of the entire PSSH box.

This also moves the Widevine proto to media base.  Now, the
Widevine key source handles creating the Widevine specific PSSH
data.

  the content.
- The message is required to separate Representations with different
  content protection information into different AdaptationSets.
