Aaron Vaage 16eff80497 Made StreamData Have Const Pointers
In prep for changes to Trick Play, we want to make all messages
copy on write so that if the same message is sent to multiple
handlers, it is not possible for one handler to change the data
another handler is using.

KongQun Yang 61c58724ec Remove size parameter in OnMediaEnd
Derive file size from media ranges instead.

Also fix subsegment range reporting for WebM (internal variable,
no output affected).

Rintaro Kuroiwa 0dfdace280 Change MuxerListener::OnMediaEnd to take ranges
- Changed OnMediaEnd() to take (sub)segment ranges.
- Define a structure to pass the ranges.
- This requires muxers to "cache" the segment ranges but in most cases,
  they already do it, e.g. 'sidx' for mp4.

- Also sets up the packaging and verify it works.

Some of the changes are temporary to get the integration going.

Kongqun Yang 80c54a533a Update cmd flags to support static mpd with live profile
- Deprecated command line flags --profile and --single_segment.
  'segment_template' in stream descriptors implies live profile
  and non-single segment.
- Added flag --generate_static_mpd_for_live_profile to generate
  static mpd for live profile; if not set, dynamic mpd will be
  generated.

Kongqun Yang 97fc9828f0 [WebM] Move index segment after init segment
Cues used to be generated in the end of the file; if http range
request is not supported, clients have to download the whole
file to get to the cues.

This CL updated TwoPassSingleSegmentSegmenter to write cues
after writing webm header.

This CL also updates libwebm dependency to latest.

Jacob Trimble a80e16bab0 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.

KongQun Yang 2ac57bf9b9 Use FOURCC as protection scheme parameter
- Remove EncryptionMode enums
- Remove AesEncryptor::InitializeWithRandomIv, replaced with
  a static function AesCryptor::GenerateRandomIv, which should
  be called to generate the iv if the iv is empty.

This change is to prepare support for CBCS and CENS pattern-based
protection schemes.

Bei Li e39c3572af Add support for "AES 128-bit Cipher Block Chaining (CBC-128) Encryption"
- Part 1.

- Add packager command line argument "protection_scheme" to specify
  protection scheme. Plumb through packager code to enable CBC
  encryption/decryption.
- Add scheme type "cbc1" to sinf.
- Refactor AES encryptor and decryptor.
- Need more work in the subsample handling.

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.

Jacob Trimble 7b52f0a3ed Added unit tests for WebM Segmenters.

  to help in testing.
* Changed MemoryFile behavior to mirror local file:
  * Read non-existent file is an error.
  * Write deletes any existing file.
* Fixed a bug in SingleSegmentSegmenter.
