c697c590fb lcl: Disentangle pointers to input data and decompression buffer
This is cleaner and avoids a cast plus a related const qualifier warning.

df9b956751 lavc: fix decode_frame() third parameter semantics for video decoders
It's got_frame, not data size

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

5bac2d0c30 avutil: Move memcpy_backptr() to mem.c
The function is used elsewhere and does not belong with the LZO code.

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.

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.

ec6402b7c5 lavc: use designated initialisers for all codecs.
It's more readable and less prone to breakage.

None of these symbols should be accessed directly, so declare them as
hidden.

b34aaed2cf Move #ifdef before zlib_decomp() up so it covers the Doxygen comments.
Otherwise Doxygen gets confused and cannot map comments to functions.

Passing an explicit filename to this command is only necessary if the

one the block resides in.
