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.

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.

It's redundant now as check in done in demuxer instead.

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.

Add error codes to expected codes to make responses faster.
Success of a command is validated by comparing code to a success code.

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)

Each send command routine requires the same steps.
This commit moves repeated code into one function.

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.

FTP server may disconnect after some period of time when no transfer is done.

FTP protocol should reconnect and seek to last position.

Move common code that opens control connection to function.
This code can be reused when reconnecting to FTP server
after inactivity.

FTP server may disconnect client.

This commit stores credentials for future reconnect.

ftp_send_command was used only once.

This commit makes this function specific, not generic

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

Checking seek table crc in decoder is pointless, as seek table is not used in
decoder anyway, so also stop storing seek table into extradata.
