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]

bsc_init.c was a big mess even only for two supported BTS models,
so before adding more BTS types, this needs a cleanup.
All the BTS specific code from bsc_init.c has now moved into
bts_{siemens_bs11,ipaccess_nanobts}.c
This has required that input_event() and nm_state_event() get both
converted to proper libosmocore signals instead of referencing external
symbols.
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.
Instead of sending many messages we will queue the OML
messages and wait for the ACK/NACK before sending the
next message from the queue. We tag the msgb to remember
if we need to wait for an ack or not.
We keep the order of all messages, on ACKs and similiar
occassions we will drown the queue until we reach a message
that needs to be acked and then wait for that ack again.
Possible breakage can appear when we send an OML (e.g.
BS11 specific message) msg which does not need to be acked
through the abis_nm_sendmsg call. The fix will be to use
the _direct version of this method.
Re-Enable as it might have fixed something... who knows.

Also, we now re-start the network listen test after it has finished,
so if you run a test from ipaccess-find, the test will get re-started
and re-started all the time.
For the multi TRX setup we will need to specify the right trx->nr
to be able to flash the BTS. For the BS11 case we are ignoring the
additional argument.
Send the IPA Restart to a given BTS/TRX, change the signal callbacks
to carry the trx instead of the BTS so we have an easy access to the
right TRX and change the ipaccess-config to use that TRX. This is
fixing the restart with a multi TRX setup.
Even if we have the msg->trx, use the gsm_bts_trx_by_nr and get
the TRX from the fom header. This is because the OpenBSC and the
BTS numbering might not match for the multi TRX case.
This new gprs-conf branch is intended to contain everything needed
to configure GPRS in the nanoBTS, but without implementing the SGSN/GGSN
functionality.
The SGSN/GGSN development will happen in a branch based on this branch
called "gprs-sgsn"
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
Some NM attributes are defined differently depending on
the BTS type. Having one big nm_att_tlvdef[] table for
all BTS types is no longer sufficient. This patch
* introduces 'struct gsm_bts_model' to describe a BTS model
* adds definitions of gsm_bts_model for BS-11 and nanoBTS
* changes the abis_nm_tlv_parse() function: include a bts pointer
Whether this function changes the set or the work value depends on your
type of login. In FACTORY login it changes the set value, in FIELD login
it changes the work value (which is what is used by the BS11 to tune the
frequency).
This returns true if the gsm_nm_state can be considered 'running'.
Note that we also accept availability==0xff (which is a code for
no value) because according to 12.21 it is perfectly valid.

Since TS 12.21 implements only SET ATTRIBUTE for some object classes,
ip.access had to extend it to be able to set attributes on arbitrary
objects. We now introduce a function implementing that message.
Partially apply 9ba65525eaa06a1768aaf35bdee98afcf8026e0a to get
rid of a compile problem. The other part of the mentioned commit
is still in the gprs branch.

This helps us to detect the frequency error of BS-11 if it is located
next to the nanoBTS 900.
If 'ipaccess-config -l' is called, it will produce a report like
<0020> ipaccess-config.c:85 TEST REPORT: test_no=0x42 test_res=0
<0020> ipaccess-config.c:108 ==> ARFCN 220, Frequency Error 22
<0020> ipaccess-config.c:108 ==> ARFCN 1, Frequency Error -37
<0020> ipaccess-config.c:108 ==> ARFCN 10, Frequency Error 0
<0020> ipaccess-config.c:108 ==> ARFCN 20, Frequency Error 11
<0020> ipaccess-config.c:108 ==> ARFCN 53, Frequency Error 5
<0020> ipaccess-config.c:108 ==> ARFCN 63, Frequency Error -4
<0020> ipaccess-config.c:108 ==> ARFCN 84, Frequency Error 11
<0020> ipaccess-config.c:108 ==> ARFCN 101, Frequency Error 0
<0020> ipaccess-config.c:108 ==> ARFCN 123, Frequency Error -52
where in this case the ARFCN 123 is the BS-11 with a frequency error
larger than all the other (regular) BTS in the vicinity.
