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 ClosureThread has been replaced by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.

Jacob Trimble 665e784cbd Move PSSH generation to EncryptionHandler.
The KeySource now only handles fetching the keys and loading any PSSH
info from the license; it will not handle generating new PSSH info
based on the config.

This will allow the PSSH generation to access to the full
EncryptionConfig so we can add additional options to it.

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.

KongQun Yang b5a73fc1d5 Refactor ProtectionSystemSpecificInfo class to struct
This is in preparation of supporting entitlement license API, where
common encryption server may return concatenated PSSHs directly.

Refactored ProtectionSystemSpecificInfo into a struct containing
concatenated PSSHs. This will make it easier to pass PSSHs around.

Also, most of the time, users of ProtectionSystemSpecificInfo do
not care what is in PSSH; so moved PSSH box parsing and building out
of ProtectionSystemSpecificInfo.

data.
