KongQun Yang c8819cb257 Add mp4 box fields for pattern encryption
- crypt_byte_block and skip_byte_block for pattern-based encryption.
- constant_iv for constant iv (used by 'cbcs' protection scheme).
- Also renamed iv_size to per_sample_iv_size.
- Also changed "bool is_encrypted" to "uint8_t is_protected" to align
  with CENC spec.

KongQun Yang 0218d9c690 Move fourccs.h and rcheck.h to media/base
- FOURCC is not a mp4 only concept. It is also used elsewhere.
- RCHECK has been used outside formats/mp4.

Also updated the FOURCC enum names to match the actual fourcc code, e.g.
FOURCC_mdat for "mdat".

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.

KongQun Yang 38c30bd7a1 Allow other text sample entries than wvtt
Before this change, the media file will fail to be parsed if it contains
non-wvtt text streams. This change allows demuxing of video and audio
streams in these media files even though the text stream is ignored.

Fixes #74.

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.

Kongqun Yang e5b6096857 Generate tkhd and pasp boxes properly with non-square pixels
- Width/Height in tkhd box should be display resolution instead of
  coded resolution.
- pasp was not generated earlier.
- Assuming SAR as 1:1 if it failed to be extracted successfully.
- Also update test files for mp4_media_parser_unittest.

This fixes Issue #35.

KongQun Yang 80db1c7bbf Handle non-MSE compliant fmp4 properly
MSE requires 'base-data-offset-present' not to be set, but FFmpeg may
generate fmp4 files with this flag though it actually uses moof as base.
Log a warning instead of failing directly in this case.

FFmpeg may also generates fmp4 files without tfdt box
(TrackFragmentDecodeTime) box, which is again non-MSE compliant. Handle
this scenario properly.

Bug: 18613712

Also fixes a test failure in SegmentTemplateTest introduced in an earlier
change.

This is a follow up to previous CL.

Generated using command:
find {media,app,mpd} -type f -exec sed -r -i 's/#include "(.*)"/#include
"packager\/\1"/' {} \;

common.gypi and mpd.gyp are also modified to take the path change into
consideration.
