Allow users of libwebm's MKV muxer to control the Track UID. This,
for example, allows creation of tests that rely on checksum comparisons
to verify output from the library.

A whole new approach to repositioning Cues before Clusters. This
patchset adds a new function CopyAndMoveCuesBeforeClusters to the
Segment class. This function should be called after
Segment::Finalize() to obtain a copy of the same output file with
Cues positioned before the Clusters.
Removing everything else that was added to accomplish the same in
the previous few commits.
Also, adding std:: qualifier to one of the variables in
sample_muxer_metadata which was missed accidentally in the previous
commit.

Changing the IMkvReadableWriter interface to IMkvWriteEOFReader.
Also changing the default implementation.

Adding support for placing Cues element before the Cluster element. We
recompute the new offsets using a recursive algorithm and update the Cues and
Seek Heads with the updates offsets.

Adding elements and functions to support muxing of BlockAdditional element.
This is required for supporting muxing of streams with Alpha Channel (where the
Alpha data goes into BlockAdditional). Detailed design doc of Alpha Channel can
be found here: http://goo.gl/wCP1y

- libwebm was writing the BlockNumber of the next Block instead
of the Block that was just written.

- Added ContentEncAESSettings, AESSettingsCipherMode,
AESSettingsCipherInitData elements to the parser and muxer.
- Changed ParseContentEncodingsEntry, ParseContentEncodingEntry,
and ParseEncryptionEntry to use PasreElementHeader.
- Added ParseContentEncAESSettingsEntry function.
- PS6 removed AESSettingsCipherInitData.
- PS9 Addressed comments, Fixed some LINT issues, and converted
mkvwriter.h/.cpp to Unix line endings.
- PS10 Addressed comments.

- 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.

Just before the first byte of an element identifier is written
the muxer calls IMkvWriter::ElementStartNotify to report the
position of the element in the WebM stream.

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.

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.

frame should be in the same cluster." Added support for
block_number in cue points. Added support for setting max
cluster size.
