Issue #64

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.

Rintaro Kuroiwa 5ad076d92c Fix schematron validation problem for live
- From DASH spec 2014, MPD@publishTime and Period@id are required for
  'dynamic' MPD.
- Period@id is always set to "0".
- MPD@publishTime is set to the time when the MPD is output.

Added packager tests for WebM audio.  Also now only outputs the
language if it's not empty.  Fixed the packager tests for that.

KongQun Yang b17d240060 Fix a memory leak due to thread object tracking
ThreadedIoFile spawns a new thread for every new file. Thread
information is stored for tracking purpose by base::tracked_objects.
The tracking object remains even if the thread itself is destroyed.
This results in memory usage increased by a couple of bytes for every
new segment created in live mode (new segments spawns new threads).

Use WorkerPool instead to avoid spawning new threads.

Fixes Issue #61.

  * Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.

Javascript/JSON does not support int64_t or unsigned numbers. asset_id,
if greater than 0x80000000 will be converted to negative number. Use
double to represent asset_id instead as 32-bit integer can be lossless
represented using double.

Jacob Trimble 8a0458c17b Added MemoryFile, a File type stored in memory.
This can be used for unit tests to reduce the need for temporary
files.  A MemoryFile acts the same as any other File object, but
stores the contents in memory.  The memory pointer can be accessed
directly.  A file with the 'memory://' prefix will be a memory file.

KongQun Yang 9c95309c12 Pull profiling dependency from Chromium
Profiling can be enabled by setting profiling=1 in gyp, e.g.
  GYP_DEFINES="profiling=1" gclient runhooks

To turn on heap profiling, use the HEAPPROFILE environment variable
to specify a filename for the heap profile dump, e.g.
  HEAPPROFILE=/tmp/heapprofile out/Release/packager ...

To turn on cpu profiling, use the CPUPROFILE environment variable
to specify a filename for the cpu profile dump, e.g.
  CPUPROFILE=/tmp/cpuprofile out/Release/packager ...

Note that profiling may not work for debug builds, so use release
build if possible.

See docs/linux_profiling.md for details.

This change will help identify and resolve problem behind Issue #61.

KongQun Yang c8e3345959 Some code clean ups in box definitions
- Add Box::WriteHeader and Box::HeaderSize methods. The concrete
  box implementations should not need care about whether it is a
  Box or FullBox normally.
- Rename Box::ReadWrite to Box::ReadWriteInternal to make it clear
  that it is an internal methods. Make it private so it cannot be
  incorrectly called in box implementions.
- Make an internal implementation of ComputeSizeInternal to compute
  box size. |atom_size| is updated in ComputeSize, which wraps
  ComputeSizeInternal.
