cbf6047c83 avcodec/frame_thread_encoder: Remove redundant memcpy 
In case the underlying AVCodec has no private class, the private data
of both the main as well as each worker AVCodecContext is just zeroed
(the codec's init function has not been called on any of them and
without a private class there is no way to legitimately set anything
before the aforementioned init function).

3f6e715336 avcodec/frame_thread_encoder: Avoid dictionaries 
avcodec_open2() allows to provide options via an AVDictionary;
but it is also allowed to set options by simply setting the value
of the AVCodecContext or via the AVOptions API if the codec has
a private class. Any options provided via an AVDictionary have already
been applied before ff_frame_thread_init(), so in order to copy
all the options from the main AVCodecContext and its private context,
it is enough to av_opt_copy() these options.

The current code does this, but it does more: It also copies the
user-provided AVDictionary and uses it for the initialization of
each of the worker-AVCodecContexts. This is completely unnecessary,
because said options have already been copied from the main context.

Furthermore, these options were also examined to decide if frame
threading should be used for huffman encoding in case this would incur
nondeterminism. This is wrong, because options not set via
an AVDictionary are ignored. Instead inspect the values stored in the
contexts directly. (In order to maintain the current behaviour, the
default value of the "non_deterministic" option has been changed to false,
because the absence of an entry with said key in the AVDictionary
had the consequence of disallowing nondeterminism.)

Finally, the AVDictionary has been removed from the signature of
ff_frame_thread_encoder_init().

de1b20a82b avcodec/frame_thread_encoder: Avoid allocations of AVFrames 
Up until now, when using frame threaded encoding, an AVFrame would be
allocated for every frame to be encoded. These AVFrames would reach the
worker threads via a FIFO of tasks, a structure which contained the
AVFrame as well as an index into an array which gives the place where
the worker thread shall put the returned packet; in addition to that,
said structure also contained several unused fields.

This commit changes this: The AVFrames are now allocated during init in
the array that is up until now only used to return the packets. The
contents to be encoded are put into the AVFrame in the same array
element that is also used to return the packets.

fbf242a51d avcodec/frame_thread_encoder: Avoid allocations of AVPackets, fix deadlock 
Up until now, when doing frame thread encoding, each worker thread
tried to allocate an AVPacket for every AVFrame to be encoded; said
packets would then be handed back to the main thread, where the content
of said packet is copied into the packet actually destined for output;
the temporary AVPacket is then freed.

Besides being wasteful this also has another problem: There is a risk of
deadlock, namely if no AVPacket can be allocated at all. The user
doesn't get an error at all in this case and the worker threads will
simply try to allocate a packet again and again. If the user has
supplied enough frames, the user's thread will block until a task has
been completed, which just doesn't happen if no packet can ever be
allocated.

This patch instead modifies the code to allocate the packets during
init; they are then reused again and again.

Fixes a segfault from av_fifo_size(NULL) that happens in
ff_frame_thread_encoder_free if the fifo couldn't be allocted;
furthermore the mutexes and conditions that are destroyed in
ff_frame_thread_encoder_free are not even initialized at this point,
so don't call said function.
