We initialize the struct to 0 to also ensure any actual use of
the pointers in it will not lead to security issues.

This function used to be shared with the xxan decoder, but that is not
true anymore.

The background changes from 128 (used by the default/cmdutils
get_buffer()) to 0. This looks more correct.

Do not overwrite linesize set by get_buffer().

The last frame in the FATE test is not decoded anymore, since the file
is cut and a part of it is missing.

This fixes the following warning with GCC:
    libavcodec/pthread.c:35:0: warning: _GNU_SOURCE redefined [enabled by default]
    <command-line>::0: note: this is the location of the previous definition

The reason of the presence of this flag is:
    % pkg-config --cflags sdl
    -D_GNU_SOURCE=1 -D_REENTRANT -I/usr/include/SDL

The description as updated in 6e5c44b0f made it sound like it is
handled exactly like the pts, which it is not. Clarify that it
is the packet that triggered returning the frame instead of just
the last avpacket (in case of frame threading, it won't be the
dts of the last packet).

The asm code is not valid for older compilers as it uses too many
operands, ICC on x86_32 seems affected by this.
This patch disables the affected code for ICC on x86_32 and should
make it compileable again.
A better fix would be to use fewer operands or to change this code
to yasm, later is being worked on AFAIK so this is a temporary
solution.

Using a frame count, as is done currently, does not work at all with
seeking. Instead, when the number of samples in the final frame has
been decoded, we check if only the 32-bit CRC is remaining. If so, we
assume that it is the final frame.

There is no longer a need to keep total_frames in TTAContext.

Beginning with version 1.5.1 openjpeg defaults to install its headers to
/usr/include/openjpeg-${major}.${minor} instead of /usr/include without
providing a compatibility symlink making the old test fail.

Sometimes the extradata has duplicate atoms, but that shouldn't prevent
decoding. Just ensure that it is at least 36 bytes as a sanity check.
