a247ac640d avcodec: Constify AVCodecs 
Given that the AVCodec.next pointer has now been removed, most of the
AVCodecs are not modified at all any more and can therefore be made
const (as this patch does); the only exceptions are the very few codecs
for external libraries that have a init_static_data callback.

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.

16bb8247b4 avcodec/mpegaudiodsp: Make initializing synth windows thread-safe 
These arrays are used by the Musepack decoders, the MPEG audio decoders
as well as qdm2 and up until now, these arrays might be initialized more
than once, leading to potential data races as well as unnecessary
initializations. Therefore this commit ensures that each array will only
be initialized once.

70d80ed40f qdm2: Allow hard-coding VLC tables. 
Also adds a lot of infrastructure necessary for it.
Some of it is a bit ugly though.
Increases binary size for hardcoded tables by about 12 kB,
which is about 15 kB from qdm2_table minus data and code
saved that was only used for creating it.
