5c5b1731b7 Maintain pointer to end of AVFormatContext.packet_buffer list
This changes add_to_pktbuf() to maintain a pointer to the last entry
in the list, avoiding a linear walk-through on each call.  Before this
change, add_to_pktbuf() could take a significant amount of time (10%
of total decoding time), even with input files of several minutes.
After the change, the time spent in this function is barely measurable
with oprofile.

40812fdcf1 Simplify range checking in eval_refl(). Before the
condition b == 0 could never be true, because it would
have already been caught in the previous ifs. Also the
condition b == 0x1000 could never be true (it would
triggered the return).

e3751aa6ec Flip (by making buf[i] -> buf[size-i-1]) two buffers: {sp,gain}_block. This
needs duplicating a few loops, but now the code is clearer.

3fa1e8185a matroskadec: update seek regression test to match new ebml parser
This change is due to r14590.
The AVPacket position now points to the first byte of the actual
packet data in the file. It previously pointed to the EBML element
ID preceding packet data.
