119974b164 adpcm_ima_wav: process channel-interleaved blocks sequentially rather than simultaneously. 
Speeds up the ADPCM IMA WAV decoder by 15-20% overall.

7c287b18a0 adpcm: update reference links 
Add Multimedia Wiki link.
Mark dead links with [dead]. Some can still be accessed through archive.org.
Update URLs for pages which have moved.
Replace duplicated links in adpcmenc.c with a note to see the ADPCM decoder
reference documents.

ac94b8bcc6 adpcm: simplify packet size bounds checking in the ADPCM IMA QT decoder. 
This is easier to understand. It also avoids returning existing samples mixed
with new samples when the packet is too small.

same buffer unless it has returned with an error. With multi-channels

8febd6afbc libgsm: split init and close fuctions for encoder and decoder. 
The decoder shouldn't be allocating coded_frame. It's also cleaner to split
them than to check avctx->codec->encode and avctx->codec->decode.

6e4a35ced9 ppc: fix 32-bit PIC build 
On 32-bit ppc, the GOT pointer must be loaded manually.
This adds a "get_got" assembler macro to compute the
GOT address.  The "movrel" macro is updated to take an
additional parameter containing the GOT address since
no register is reserved for this purpose on ppc32.
These changes have no effect on ppc64 builds.

baad01d8b4 h264: improve checks before calling ff_h264_decode_extradata 
The ff_h264_decode_extradata routine now checks for the buffer size
and pointer internally. This makes it possible to remove the external
checks in ff_h264_decode_init.

  In decode_frame there was a size check missing because the buffer
gets tested prior to the invocation of ff_h264_decode_extradata().

The buffer size and pointer were not checked prior to testing the first
byte of the buffer. These were sometimes checked before calling, but it is
better to add it inside the function as it takes buf and size arguments.
