Use the formats.h API instead.

This is more consistent with naming in the rest of Libav.

The declaration order is more meanigful in most cases.

Prevent an out of array bound write.

Currently, if VIS is enabled by configure, it will also be enabled at
run-time regardless of its support in the hardware. Thus, masking VIS
usage as it is done in vis.h by constructing binary instructions is
pointless. Using normal VIS mnemonics in inline assembly allows to take
advantage of automatic register allocation, gets rid of register
variables, which are unsupported by suncc for SPARC, and improves code
readability.

MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.

Those were useful when avcodec_thread_init() was a public functions. It
was deprecated and removed some time ago, so those checks are not needed
anymore.

Do not leak all the temp buffers.

Do not leak the x/y expressions.

Do not overwrite the variable set through AVOptions.

Do not overwrite the variables set through AVOptions.

Frame number should be incremented normally even if the link properties
change.

It should not be reinitialized if the link properties change.

Do not leak the initialized filter instance.

Do not leak the expressions.

According to the PIFF specification[1] the base_data_offset field MUST be
omitteed. See section 5.2.17. Since the ISMV files created by libavformat
state that they are 'piff' compatible via 'ftyp' box, this needs to be
corrected.

The condition cannot happen anymore.

When JPEG-LS support is disabled the decoder would feed the
data to the JPEG Lossless decode_*_scan function resulting in
faulty decoding.
