typefind: Export AAC level in caps

I'm attaching a patch to export the AAC 'level' in caps. This could be used
while linking (for example, a hardware decoder might support AAC LC upto level
2), and is useful metadata for certain applications (the DLNA spec requires
that the level of a stream be known).

I've made the level a string to account for codecs that have non-numeric levels
(for example, H.264 has a level '1.b').

The level calculation code will initially be duplicated across modules (for
qtdemux and matroskademux) because it's a rather smaller bit of code.
Eventually, as the amount of shared AAC-related code increases, we can move
this to -base as a library.

I'll post the code for level guessing in qtdemux after this patch is reviewed
to avoid causing bug-spam.
