Harald Welte 3e04ed6083 gsmtap: Add GSMTAP_GPRS_CS() / GSMTAP_GPRS_MCS()
As requested by Mike Morrin <Mike.Morrin@ipaccess.com>, we introduce
GSMTAP sub-types for all the different GPRS and EGPRS coding schemes.

This is neccessary due to the fact that the RLC PDU doesn't contain any
explicit indication of the coding scheme used on the radio layer.

Andreas Eversberg c1a91a896f gsm/sms: Rewrite of SMR process, extracted from OpenBSC
The SMR process is used to transfer SMS TPDUs. It is now extracted from
OpenBSC. It includes a real state machine now for easier debugging.

Also it implements the TR1M and TR2M timers. The memory notification
procedure is missing, but not required for network side.

Sylvain Munaut 2179f402e0 core/rbtree: add const qualifier to some functions
See kernel commit f4b477c47332367d35686bd2b808c2156b96d7c7

----
The 'rb_first()', 'rb_last()', 'rb_next()' and 'rb_prev()' calls
take a pointer to an RB node or RB root. They do not change the
pointed objects, so add a 'const' qualifier in order to make life
of the users of these functions easier.

Indeed, if I have my own constant pointer &const struct my_type *p,
and I call 'rb_next(&p->rb)', I get a GCC warning:

warning: passing argument 1 of ?~@~Xrb_next?~@~Y discards qualifiers from pointer target type

Pablo Neira Ayuso 066c912fd3 timer: add scalable RB-tree based timer infrastructure
This patch adds RB-tree based timers which scales better than the
previous list-based implementation.

It does not require any API changes. It breaks ABI because the
osmo_timer_list structure has changed though (to avoid this in
the future, we can put internal data in some private structure).

The following table summarizes the worst-case computational complexity
of this new implementation versus the previous one:

                                rb-tree         list-based
                                -------         ----------
calculate next timer to expire  O(1)            O(n)
insertion of new timer          O(log n)        O(n)
deletion of timer               O(log n)        O(1)
timer-fired scheduler           O(log n)        O(3n)

The most repeated cases are:

* the calculation of the next timer to expire, that happens in every
  loop of our select function.

* the timer-fired scheduler execution.

This new implementation only loses in the deletion of timer scenario,
this happens because we may need to rebalance the tree after the
removal.

So I think there is some real gain if we have some situation in which
we have to handle lots of timers.

Pablo Neira Ayuso f74db0b33d add rb-tree implementation to libosmocore
This patch adds red black trees implementation to libosmocore.
This data structure is very useful to search for elements in
ordered sets in O(log n) instead of O(n) that lists provide.

The first client of this code will be one follow up patch that
implements rbtree-based timer scheduler.

root af48bed556 Split of LAPDm into a core part and a GSM specific part
Instead of mixing together the GSM layer 1 interface and RSL interface
with the implementation of LAPD, the core function of LAPD is now
extracted from LAPDm. The core implementation is now in lapd_core.c
and lapd_core.h respectively.

The lapd_core.c implements exactly one datalink instance for one SAP.
The surrounding implementation "lapdm.c" codes/decodes the layer 2
headers and handles multiplexing and datalink instances, as well as
translates primitives from/to RSL layer.

lapd_core.c can now be used for other LAPD implementations. (ISDN/ABIS)
