For WebM contents, it is possible that we may receive some NewSampleEvent
before receiving ParserInitEvent. This is because init event is fired
after analyzing a video block which could come after an audio block.
Also modified Flush() function to return a bool to indicate whether the
the flush is successful and whether the samples are handled correctly.
And added macro to ensure Flush() and Parse() results are handled.

Cropping is necessary if width/height are not exactly disivible by 16 due
to 16x16 macroblock size.
The width and height fields in VisualSampleEntry must correctly document
the cropped frame dimentions (visual presentation size) of the AVC stream
that is described by that entry.
Also fixes width/height in input mp4 and wvm streams if the values in
VisualSampleEntry / metadata do not match with the values in
AVCDecoderConfigurationRecord (SPS).

This fixes a circular dependency of media_base depends on filter and
filter depends on media_base.
Also added code to extract sar in WvmMediaParser if it is not yet
extracted when setting extra_data.

- Added logic to container parsers to extract pixel width and height.
- If the container doesn't contain the pixel width and height of the
stream and the stream is H264, this parses the SPS to get the
sar_width and sar_height.
- If extracted sar_width and sar_height are 0s then they imply 1s.
- Add hb2_v_frag.mp4 for test media. This does not have a
'pasp' box and has sar_width = 8 sar_height = 9.

Fix b/18005827 Packager crashes in debug mode with widevine decryption

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.
