Also reduce verbosity for the unsupported stream message, use
an AVFormatContext for av_log and and print the tag of the
unknown stream.

Improves ticket #672.

The common non inlined code goes in snow.c, the common inlined code in
snow.h, tables move in snowdata.h (included only by snow.c)

isGray() is left as a FIXME for later.

If the sample format is invalid, av_get_sample_fmt_name() will always
return NULL.

The number of used channels need to be reset to zero when
swr_alloc_set_opts() is called successive times.

This is a regression introduced in c8136ebd.

The qatar implementation makes no sense.
a muxer without timestamps is constant fps thus needs vsync.
the crc/mp5 are special cases that have timestamps yet allow any
nonsensical timestamps.
raw (yuv/rgb) video is constant fps thus needs vsync too.

At EOF it makes no sense to modify avpkt.{data,size} in output_packet
since no data is consumed. Frame threading with more than 1 threads
hits the segfault.

I.e. if the packet was only partially consumed, pass the rest of it into
the decoder again.

Also simplify the code so it's the same for video/audio/subs.

Also check for sufficient packet size.

AVFMT_NOTIMESTAMPS for crc, as it ignores the timestamps.
AVFMT_VARIABLE_FPS for framecrc, as it prints dts.

Many FATE changes, because avconv is no longer duplicating frames in
those tests.
Also added -vsync 0 for some tests to prevent avconv from dropping
frames until it can be fixed more properly.
