be129271ea lcl: error out if uncompressed input buffer is smaller than framesize.
This prevents crashes when trying to read beyond the end of the buffer
while decoding frame data.

Passing the codec into avformat_new_stream() is preferred.

2784d18791 SBR DSP x86: implement SSE sbr_hf_g_filt
Unrolling the main loop to process, instead of 4 elements:
- 8: minor gain of 2 cycles (not worth the extra object size)
- 2: loss of 8 cycles.

Assigning STEP to a register is a loss. Output address (Y) is almost always
unaligned.

Timings:
- C (32/64 bits): 117/109 cycles
- SSE: 57 cycles

34454c761f SBR DSP x86: implement SSE sbr_sum_square_sse
The 32bits targets have been compiled with -mfpmath=sse for proper reference.
sbr_sum_square C  /32bits: 82c (unrolled)/102c
               C  /64bits: 69c (unrolled)/82c
               SSE/32bits: 42c
               SSE/64bits: 31c

Use of SSE4.1 dpps to perform the final sum is slower.
Not unrolling to perform 8 operations in a loop yields 10 more cycles.

480b133e6f wavpack: Don't shift minclip/maxclip
Since we are clipping before we shift the values to
16 or 32 bits, we should not shift the min/max clip
values to compensate.

ba605cef79 rtpenc: Expose the max packet size via an avoption
This allows opting for a lower MTU than what the AVIOContext
indicated, and allows writing into outputs that don't indicate
an MTU at all (such as plain files, which is useful for testing).

This also allows querying for the MTU via the avoption.

b315042c8c Remove libpostproc.
This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

01cb62aba2 lcl: don't overwrite input memory.
If the PNG filter is enabled, a PNG-style filter will run over the
input buffer, writing into the buffer. Therefore, if no zlib compression
was used, ensure that we copy into a temporary buffer, otherwise we
overwrite user-provided input data.
