AESSettingsCipherInitData elements to the parser and muxer.
- Changed ParseContentEncodingsEntry, ParseContentEncodingEntry,
and ParseEncryptionEntry to use PasreElementHeader.
- Added ParseContentEncAESSettingsEntry function.
- PS6 removed AESSettingsCipherInitData.

In several cases, the parser would parse a header
(say, a track header, or the segment info header)
in the constructor for the type. The parser had
assumed (incorrectly) that the file was well-formed,
but this turned out to be an incorrect assumption.
The parse errors triggered some assertion failures,
but this is not acceptable in a production system.
The parser solved that problem by separating the
construction of the header object from the parsing
of the file. There is now a separate parse method
to be called after construction of the object,
which returns a status whether the parse was
successful.
This change fixes the bugs from the following
tracker issues:

- Fixed a bug with the muxer where it would generate a entry in
the SeekHead for a Cues element with OutputCues set to false.
- Fixed a bug with the muxer where it would generate an empty
Cues element with OutputCues set to false.

- There was a bug where the calculation for the audio and video
track size where the code would calculate the size of the track
elements minus the size of the audio or video elements. If the
coded size of the track elements was one byte smaller than with
the audio or video elements then the muxer would return an
error.
- Fixed another issue that the track's virtual Size function was
calling the Track's PayloadSize function where it should have
been calling the virtual PayloadSize function.

There was a potential bug with calculating the size of a master
element. The size was being calculated with a straight unsigned
integer when it should have been calculated with a coded
integer.

Fixes reliability issue with IMkvWriter::ElementStartNotify: the
cluster and segment IDs were being written with SerializeInt instead
of WriteID.
Also:
- Remove completed TODO.
- Fix method declaration order in MkvWriter.

Segment::AddFrame will now return false (fail) when a non-monotonically
increasing timestamp value is passed to the method.

NDEBUG is defined in our release build, which allowed for misuse of
the library by users that would result in dereferencing NULL
MkvWriter pointers in various places throughout the muxer code.
Change-Id: I6ab51453ef26786ca988310c051bb49db16ecbc5
Remove asserts on the MkvWriter pointer in each constructor,
and assign the pointer in each Init method. Update Segment::Init
usage site in sample_muxer.

Added support for the ContentEncoding element to be added to a
Track element for muxing. Currently only one ContentEncoding may
be added. The ContentEncoding must be encryption of the whole
frame with AES.
Added support for parsing the ConentEncoding elements. Currently
the parser does not parse any ContentCompression elements.

If the muxer had audio frames that were earlier in time than the
first video frame then the first cluster would not be initialized
in time to write out the first audio frames.

Changed max_cluster_duration to 30 seconds so default command line
will not crash on audio only WebM files. Added support to the sample
muxer to output cues on the audio track. Created a muxer helper
function to clean up the code a little.
