b716542691 mpegaudiodec: Prevent premature clipping of mp3 input buffer. 
Instead of clipping extrasize based on EXTRABYTES, clip based on the
amount of buffer actually left. Without this fix, there are warbles
and other distortions in the test case below.

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.

Fixes 8 and 24 bit lossy decoding.

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.
