Now Finalize() will close all the files used by the segmenters.  This
is important to allow WebMMuxer::FireOnMediaEndEvent to get the
correct size of the media file.

This also changes the WebM muxer to use 64-bit numbers for the init
and index ranges to correctly support >4GB files.

Jacob Trimble c4246d04fd Change FetchKey usages.
Add another overload to fetch by key ID directly, used by WebM.
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.

Jacob Trimble 9d67f545ed Add support for v1 PSSH boxes.
This moves pssh parsing to its own class in media base.  This type
can be used to parse and generate pssh boxes.  This new type also
supports both v0 an v1 boxes.

This also modifies the pssh box definition to only have the |raw_box|
and moves all pssh parsing and handling into mp4 media parser.

A follow-up change will replace the remaining usages of 'raw' pssh
box data with the new type.

- Added factory methods for creating Representation and AdaptationSet in

- 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.
