Instead of generating the default codecs list for a RAN for each call,
place a pre-composed list in ran_infra.c.
(1) The main aim is to allow configuring this list -- subsequent commit
Ib5655214ce48c66d095e8f1b7b7106ac3ee43ec0 will add the VTY commands to
modify the predefined lists.
(2) As a free side effect, this also allows configuring the order of
preference for specific codecs.
(3) It may also save us some iterations of the codec_map[], which may
grow a lot more variants; for example, we could add one entry for each
possible AMR mode-set...

When we get the codec filter result logged, it is most interesting to
know the caller. So wrap a file-line macro around trans_cc_filter_run().

Bearer capability 3k1_AUDIO and FAX_G3 are only important
for the interworking function, the MSC should handle
these calls the same as CSD calls with unrestricted digital
bearer capability.

Move remote out of codecs, as it will be used by CSD code as well.
Otherwise we would need to store it twice (in cc.codecs.remote and
cc.csd.remote).

In all the places where codec_filter_ functions get called, for CSD we
will need to filter the bearer services. Add a new
transaction_cc.c file for functions that either combine the
codec_filter_ function with logic for CSD and voice calls or just call
the existing codec_filter function and a new csd_filter function.
Start with moving codec_filter_set_ms_from_bc to this new file, it will
be extended with a case for CSD in a future patch.
