Jacob Trimble 2ef100e87d Close files in Finalize for WebM segmenters.
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 bb3918e62b Sets the duration of the last frame in WebM Cluster.
This also changes the way frames are written in the WebM muxer.  Now,
frames are stored and written on the next call to AddSample.  So each
call to AddSample will write the previous frame.  This is needed to
determine whether the given frame is the last one in the cluster.

Closes #70

Jacob Trimble d1d75f477c Add encryption support to WebM.
This does not support key-rotation and will give an error.  This is
because WebM does not have a way to indicate a change in key ID using
media segments.
