Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.

check AVCodecContext->sample_fmt against AVCodec->sample_fmts[] to ensure
that the encoder supports the specified sample format. Error out if it doesn't.
Previously, it would continue and output garbage. Fixes issue 2587.

As a side effect of the last commit, avcodec_open() now calls it automatically,
so there is no longer any need for clients to call it.
Instead they should set AVCodecContext.thread_count.

avcodec_thread_free() is deprecated, and will be removed from avcodec.h at the
next MAJOR libavcodec bump.

Rename the functions to ff_thread_init/free, since they are now internal.
Wrappers are provided to maintain API compatibility.

Due to being pants-on-head retarded, libavcodec defaults this to zero, which
results in broken output.  This didn't affect ffmpeg.c, which sets it itself,
but caused problems for other calling apps using VBV.

Fix emu_edge_v_extend_15 to be <128 bytes on Win64, by being more strict

where multiple are available. This fixes segfaults in emulated_edge()

Currently (since the data_offset fix) the ogg demuxer assumes that
after the first non-header packets in any stream no more header packets
will follow.
This is not guaranteed, so change the code back again to wait until it
has finished the headers for all streams before returning from ogg_get_headers.

This fixes issue 2428.
