doc/APIchanges: add missing hashes and dates
fate: add CVFC1_Sony_C to h264 conformance tests

because cropping wasn't fully supported before.

lavu: fix GET_UTF8 macro.

Prevent 0xFE and 0xFF from being considered the start of
non-standard 7-bytes sequences. No noticeable effect on speed.
lavc: check decoded subtitles encoding.

Address trac ticket #2431.
vc1dec: redesign the intensity compensation

The existing implementation had little to do with VC1.
This could be implemented by adjusting the reference frames
ithemselfs but that would make frame multi-threading difficult.

lavf: introduce AVFMT_TS_NEGATIVE

Most formats do not support negative timestamps, shift them to avoid
unexpected behaviour and a number of bad crashes.

doc: remove all-components.texi, include its content verbatim

Force re-generation of the manuals when an included file is modified.
The current dependency generation system is enable to track nested
inclusions.

The drawback is that the files will be generated even when there is no
strict need (for example if filters.texi is modified, ffmpeg.1 is
rebuilt), thus it trades a false negative with a false positive.

dcaenc: update

Long story short: previous code was useless and was port of older
dcaenc, this commit just "sync" with current dcaenc, hopefuly
making this encoder more useful.
