Showing A-V diff has no use if there is no audio and video stream, but showing
the audio or video clock difference to the master clock can be useful.

It was raised to 4 because of a theoretical issue, if we ensure that we do not
return from the display function without popping one picture from the queue,
then its OK to use the old size.

Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or
provided in case the user compiles with hardcoded tables) with only 257 elements.
We're missing a considerable boost in performance by not making them with a size
of 1024 elements instead.

* commit '14fb9d3d8ccf5f50180aabdb1afe8b570fea3d28':
configure: Separate commonalities in msvc and icl flags
Conflicts:

Indeo 4 has quantiser range 0-31 instead of 0-23 for Indeo 5, and clipping
quantiser leads to incorrect quantisation and DC prediction on low-quality
videos.
This fixes bug 259.
Since we don't check for seek table integrity in the decoder anymore,
check it in the demuxer instead (Only tta files are guaranteed to have
one, and it should be valid there).
Check also for header integrity, since the check done in the decoder
is ignored because matroska doesn't store the header at all.

Allows for easier handling of flags that may be specific to icl or msvc.
Furthermore, simplify the handling of warnings and remarks thanks to
icl's support of -Wall on Windows.

ABOR command usually takes long (FTP server implementation dependent).
It also produces different response codes from different servers.
It is save for ffmpeg to reconnect both connection during seek for two reasons:
1. Alreay mentioned heavy manner of ABOR command.
2. Server may disconnected due to no transfer (seek after a long pause in ffmpeg client)
Reimplementation of ftp_status function.
New version requires explicit list of expected codes.
It flush data connection input before sending a command
and blocks until expected result appears.
This is based on jpeg2000 but differs because of
problems with the design from jpeg2000 with currently
supported files
More files can be decoded after this commit, though they
show heavy artifacts

Adding an arbitrary amount of padding bytes at the end of the
ID3 metadata fixes cover art display for some software (iTunes,
Traktor, Serato, Torq).
For reference (ID3 metadata):
[ Apic frames ] -> cover doesn't show up
[ Apic frames, Padding ] -> ok
[ Apic frames, ID3 frames ] -> ok
[ ID3 frames, Apic frames ] -> cover doesn't show up
[ ID3 frames, Apic frames, Padding ] -> ok
