Don't lock the channel output configuration based on the first value seen for
...
non extradata formats. Instead lock it only after the successful decoding of a
frame. This fixes issue 999.

Ignore subsequent channel configurations after the first in an AAC file. The

current code doesn't handle them properly, and they are a dubious construction
at best.

Globally rename the header inclusion guard names.

Consistently apply this rule: the guard name is obtained from the
filename by stripping the leading "lib", converting '/' and '.' to
'_' and uppercasing the resulting name. Guard names in the root
directory have to be prefixed by "FFMPEG_".
