pthread_frame: merge the functionality for normal decoder init and init_thread_copy

Browse Source 
The current design, where
- proper init is called for the first per-thread context
- first thread's private data is copied into private data for all the
  other threads
- a "fixup" function is called for all the other threads to e.g.
  allocate dynamically allocated data
is very fragile and hard to follow, so it is abandoned. Instead, the
same init function is used to init each per-thread context. Where
necessary, AVCodecInternal.is_copy can be used to differentiate between
the first thread and the other ones (e.g. for decoding the extradata
just once).

@ -51,9 +51,6 @@ the decode process starts. Call ff_thread_finish_setup() afterwards. If
some code can't be moved, have update_thread_context() run it in the next
thread.
If the codec allocates writable tables in its init(), add an init_thread_copy()
which re-allocates them for other threads.
Add AV_CODEC_CAP_FRAME_THREADS to the codec capabilities. There will be very little
speed gain at this point but it should work.
