Seeing occasional build breaks when building hls_builder, e.g.

indirectly (through media_base), it does not work all the time.
Looks like the proto has to be a direct dependency.

When generating ninja files we end up with two libwebm targets.
packager/media/formats/webm/webm.gyp:webm -> becomes target libwebm
packager/third_party/libwebm/libwebm.gyp:libwebm -> becomes target libwebm
Solve this conflict by renaming libwebm.gyp:libwebm to mkvmuxer.
There is a target name conflict between packager/base/base.gyp:run_all_unittests and
media_test.gyp:run_all_unittests. Change to media_test.gyp:run_tests_with_atexit_manager to
resolve the conflict.
On Linux the generated ninja files use path/libbase.a as target name.
In the Mac ninja file the target is just libbase.a.
As we have two libbase.a (base/base.gyp and media/base/media_base.gyp) the linking stage fails to include both libs.
Solve by renaming media_base.gyp's base target to media_base
For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.
Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.
And added macro to ensure Flush() and Parse() results are handled.

* Changed Segmenters to accept StreamInfo rather than MediaStream
to help in testing.
* Changed MemoryFile behavior to mirror local file:
* Read non-existent file is an error.
* Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.

Javascript/JSON does not support int64_t or unsigned numbers. asset_id,
if greater than 0x80000000 will be converted to negative number. Use
double to represent asset_id instead as 32-bit integer can be lossless
represented using double.

- Replaced urn:mpeg:DASH:schema:MPD:2011 with
urn:mpeg:dash:schema:mpd:2011. The former is from the old spec.
- Replaced the MPD schema with the latest one.
- Fixed subSegmentAlignment typo with subsegmentAlignment.

This can be used for unit tests to reduce the need for temporary
files. A MemoryFile acts the same as any other File object, but
stores the contents in memory. The memory pointer can be accessed
directly. A file with the 'memory://' prefix will be a memory file.

- Parse vp9 bitstream to get vpx codec configuration
- Add subsample encryption for vp9
- Also fixed a bug in VP9 parser if segmentation update_map is enabled

Profiling can be enabled by setting profiling=1 in gyp, e.g.
GYP_DEFINES="profiling=1" gclient runhooks
To turn on heap profiling, use the HEAPPROFILE environment variable
to specify a filename for the heap profile dump, e.g.
HEAPPROFILE=/tmp/heapprofile out/Release/packager ...
To turn on cpu profiling, use the CPUPROFILE environment variable
to specify a filename for the cpu profile dump, e.g.
CPUPROFILE=/tmp/cpuprofile out/Release/packager ...
Note that profiling may not work for debug builds, so use release
build if possible.
See docs/linux_profiling.md for details.
This change will help identify and resolve problem behind Issue #61.

- Add Box::WriteHeader and Box::HeaderSize methods. The concrete
box implementations should not need care about whether it is a
Box or FullBox normally.
- Rename Box::ReadWrite to Box::ReadWriteInternal to make it clear
that it is an internal methods. Make it private so it cannot be
incorrectly called in box implementions.
- Make an internal implementation of ComputeSizeInternal to compute
box size. |atom_size| is updated in ComputeSize, which wraps
ComputeSizeInternal.

Added two stream descriptors that are both used to tell the output
format. If it is not given, the packager will use the output file
extension to determine the output format.

* Added WebM muxer that supports both single and multi-segment modes.
* WebM muxer supports MPD generation.
* Enabled WebM muxer and demuxer in packager.

- Also set --clear_lead to 1 if encryption is enabled to make sure some
of the segments are encrypted.
- Also fixed glint errors.

- Check whether if it can be parsed by libxml2 and check if the root
element is a 'tt' element.
- Added unit tests for determining TTML and WebVTT.
Change-Id: I4fea1881f0ab70970700601d8d7cea32cc04752c
- Since most use cases use notifier implementations that already uses
locks, removing locks from MpdBuilder.
- Added locks to MpdNotifier::Flush() implementations. Multiple threads
were able to write to the same file.
Issue #45, #49
Change-Id: I6e39824485672f40e6c947da97f1743fac174167
- Added ignores.txt file. When doing a tsan build,
tsan_blacklist gyp flag should point to the file.

Also update the code to generate CompressorName in VideoSampleEntry
for both AVC1 and various VP codecs.
Change-Id: I2355f8008a72806e852aa1ec6c80e9141b97d963
- Added factory methods for creating Representation and AdaptationSet in
tests.
- Since most tests only needed access to the constructors for
Representation and AdaptationSet, instead of using
FRIEND_TEST_ALL_PREFIXES() for each test case, added factory methods
on the test class.
- Check the 'frameRate' attribute in
CommonMpbBuilderTest.SetSampleDuration.
