657ccb5ac7 Eliminate FF_COMMON_FRAME macro.
FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied
to struct Picture.  Replace by an embedded AVFrame structure in struct Picture.

d36beb3f69 Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf.
None of these symbols should be accessed directly, so declare them as

This moves the DWT functions from snow.c and dsputil.c to a file of

2c8077621b Optimize ff_snow_horizontal_compose97i.
this makes the 9/7 C wavelet at the decoder side 22% faster.
The old code is changed to match the new in terms of the order of operations
(which also makes it sligtly faster)
