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 96abd90ca2 Only encrypt video slice NAL units.
For non-video slices, the data is not encrypted.  This also skips the
frame headers for H.264; support for H.265 will be added later.

KongQun Yang 15ae26e12f Modify include headers to have "packager" in the path
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.
