Jacob Trimble 0803e31836 Read SPS/PPS Nalus from decoder configurations.
Now the AVCDecoderConfiguration and HEVCDecoderConfiguration classes
will read the Nalu from the blocks, meaning they will store a
vector of Nalu objects for the data.

Also added H.265 to the Nalu class and added argument to NaluReader
to read H.264 vs H.265 Nalus.

Jacob Trimble 53e6d2d149 Renamed Nalu |data_size| to |payload_size|.
This member refers to the size of the payload (the data after the
header).  Since the pointer is called |data|, calling this size
|data_size| is confusing.

Jacob Trimble 0d3951ff74 Moved Nalu data pointer position.
Now the Nalu data pointer points to the start of the NALU header
rather than pointing to the start code.  Added a new method on
NaluReader to check whether the stream starts with a start code.

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.

Jacob Trimble 890c601dce Split NALU enumeration into its own class.
Removed the code for NALU splitting in the H.264 parser and moved
it to its own class.  Also added support for length-prefixed
NALU splitting for use with the encrypting fragmenter.

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.
