This is Harald's reworked MNCC base, slowly heading towards integration
into master. The key changes are:
* provide much more structure to the data in gsm_mncc
* encode_* and decode_* functions now take a structure rather than tons
of individual arguments (whose order nobody can remember)
* make sure we don't have copies of the same code everywhere by introducing
mncc_set_cause() and mncc_release_ind()
* save horizontal screen space if possible
* make sure we break lines > 80 characters
Implement subscr_get_channel and subscr_put_channel to
a degree that SMS Submit and phone call scheduled at the
same time will deliver both (one after the other).
Reuqests for a subscriber a stored within the gsm_subscriber
datastructure and it will keep track how many channels are
allocated for this user and of which type to decide on policy...
e.g. attempt to submit SMS during a phone call and not doing
paging but a simple (immediate) assignment of the channel...
When trying to operate a nanoBTS900 on channels for 1800
or the other way around the "SET BTS ATTRIBUTES" message
will be nacked. Dispatch all nacked messages from abis_nm
via signals. Handle this in bsc_hack.c, print a small hint
and exit the application as this is considered a fatal
unrecoverable error (the exit is in the app, so a library
can be more robust).
this patch implements the encoding/decoding of 04.08 call control information
elements. It adds new functions to be used for the application interface
patch, and is basis for the application patch (currently patch 36).
Please ignore warnings about unused static functions for now.
