594d4d5df3 lavc: add a wrapper for AVCodecContext.get_buffer().
It will be useful in the upcoming transition to refcounted AVFrames.

It's more readable and less prone to breakage.

737eb5976f Merge libavcore into libavutil
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

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
hidden.

2d162e3825 Make ff_cmap_read_palette static to libavcodec/iff.c. Delete iff.h.
The iff.h header only declared one function that is now static, the
libavformat/iff.c source file wasn't using it before. Drop the file
entirely.

79a9672d45 IFF: decode last 8 pixels per line
The decodeplane8() function processes one byte of input less than
it should.  Also, the for loop has an unusual style with side-effects
in the controlling expression; replaced with a more intuitive while
loop.

473147bed0 Switch some ints to unsigned (they can only have positive values, this allows
compiler to optimize some math from mul/div to shr/shl). Also add a cast to
uint32_t when calling decodeplane32(), this silences a compiler warning.
Lastly, in decodeplane8/32(), flatten a double-loop into a single-loop and
calculate the length once before entering the loop instead of during every
iteration (since it doesn't change).
