Anton Khirnov e15371061d lavu/mem: move the DECLARE_ALIGNED macro family to mem_internal on next+1 bump 
They are not properly namespaced and not intended for public use.

Hendrik Leppkes 494f868e93 avcodec: set AV_CODEC_CAP_CHANNEL_CONF on decoders which set their own channels 
The decoders in this set either have a fixed channel count, or read it
from the bitstream, and thus do not require the channel count as
external information.

Fixes various regressions since
81503ac58a, which requires a valid channel
count for decoders which do not set this capability.

Anton Khirnov 1f4cf92cfb pthread_frame: merge the functionality for normal decoder init and init_thread_copy 
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).

When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.
