ttadec: fix last frame handling when seeking
...
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.

configure: consider using /usr/include/openjpeg-1.5 when searching for openjpeg
...
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.
