93505a9095 tools/target_dec_fuzzer: add a custom get_buffer2() implementation
Unlike avcodec_default_get_buffer2(), this version does not allocate more than
what the lavu image helper functions consider should be allocated for a given
frame.
Since the get_buffer2() documentation does not require any kind of buffer
padding for any of the planes, this should help detect bugs in our DR1 decoders
if they read beyond the end of the buffer, simulating what some library users
might experience when they use their own custom get_buffer2() implementations.

20f9727018 avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec
Up until now, codec.h contains both public and private parts
of AVCodec. This exposes the internals of AVCodec to users
and leads them into the temptation of actually using them
and forces us to forward-declare structures and types that
users can't use at all.

This commit changes this by adding a new structure FFCodec to
codec_internal.h that extends AVCodec, i.e. contains the public
AVCodec as first member; the private fields of AVCodec are moved
to this structure, leaving codec.h clean.

29c95765e8 tools/target_dec_fuzzer: move maximum variables into function
This fixes an issue when multiple cases are fuzzed in a single run and
the limits are adjusted by more than the iteration limit. In that case
the adjusted limit leaked back into the global limit causing the
fuzzer to become ineffective after several iterations, MSS2 was
affected by this for example.
