Change the MSC transaction code to operate on a GSM Subscriber Connection
instead of the lchan. This will help us to separate the two commands properly.

This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC

Since the MNCC API can now send and receive frames to/from the MNCC
application, we can also implement a proxy this way. Not at the RTP/UDP packet
level, but at the 'TCH speech frame' level.
Especially for handover, we need this mode as the receiver in the BTS needs a
persistent SSRC and monotonic frame numbers / timestamps.
|
|
This is just the minimal support to receive and send EFR codec
RTP frames.
We are missing the code to convert TRAU frames in EFR format!

This introduces a new LOGP() macro together with LOGL_* definition to
support multiple log levels (severities) throughout the codebase.
Please note that the actual logging system does not use them yet,
in this patch we simply introduce the new macros at the caller site.
|
|
As we currently really only deal with voice/speech calls and don't
support FAX and DATA (CSD) calls, we now gracefully reject them.
|
|
the various constructors get called in a non-obvious, linker determined
order, which makes certain objects disappear from the talloc report.
This change moves the talloc context creation into a new talloc_ctx.c file
|
|
This is much more optimal than checking if the context exists every
time we allocate the respective object.

Introduce a gsm48_cc_cause enum and use it from gsm_04_08 and MNCC,
also make sure we use gsm48_cause_loc rather than plain numbers.

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
