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.

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.

lavc: set defaults in internal codec frames
...
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.
