The RF lock excluded BTS was not paged at all. Now forward the
paging message to the handler and call a function that will check
if this LAC can be paged right now. Introduce a new paging method
that allows to page on a dedicated bts, refactor the code to use
this method for paging.
The code to create the struct gsm_bts is in libcommon right now
and we can not call paging_init from there. Right now it appears
to be the easiest of doing the init internally.
libosmogsm is a new library that is distributed in the libosmocore.
Now, openbsc depends on it. This patch gets openbsc with this
change.
This patch also rewrites all include path to the new
osmocom/[gsm|core]

The reason for this is quite simple: We want to make sure anyone
running a customized version of OpenBSC to operate a network will
have to release all custom modifiations to the source code.
Start counting the attempts of each paging request and call
the callback with the PAGING_BUSY type when the paging request
timed out but the subscriber was not paged at all. This can
only happen with a huge paging backlog.
In case the system has so many pending paging
Do not use the lchan for the paging but operate on the
subscriber_connection, change the signals too to not carry
the lchan but the subscriber connection... the silent call
and vty code still assume there is a lchan inside the
subscriber connection.
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
this enables the caller to detect if the paging request was rejected
by the paging layer, especially in case it is already paging this very
subscriber.
In the case of SMS / 04.11, we used to have a memory leak of struct gsm_sms's,
since we would only free them from the paging succeeded/expired callbacks.
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...
