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.

Anders Hasselqvist cb8de4c2f4 MacOSX: Solve conflicting libwebm targets
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.

Anders Hasselqvist db7bebe3fa MacOSX: Solve libbase.a conflict link error
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

KongQun Yang 940c3571aa WebMParser: set duration and dts correctly
- dts was not set earlier, although for WebM, we could assume that
  dts is the same as pts.
- Calculate block duration with the difference with the next block
  if duration is not encoded, even if track default_duration is set.
- Use track default_duration as a duration estimate for the last
  block.
- This also removes opus duration computation from encoded data.

Issues #67, #68

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.
