bhargava 350533cc32 Modify SI 13 field to support 11 bit RACH
System Information 13 field EGPRS PACKET CHANNEL REQUEST is
modified to support 11 bit RACH. Further VTY configuration is added
to enable/disable 11 bit RACH support in EGPRS. By default 11 bit
RACH support is disabled.

Neels Hofmeyr e3dc498e01 debug log: fix line endings for abis_rsl_rx_rll logging
This function outputs a debug log without line ending, which should be
completed by a subsequent DEBUGPC(), so complete the started log line where
missing in three of the switch cases.

The three cases do print another log message, but since these don't start on a
new line when RLL is in debug level, the log output for these is hard(er) to
read without this patch.

Neels Hofmeyr 745857277c code dup: join [rsl_]lchan_lookup() from libbsc and osmo-bts
lchan_lookup in abis_rsl.c and rsl_lchan_lookup() from osmo-bts rsl.c are the
same code, except for the log context, which is only set in abis_rsl.c.
Factor out the common code to rsl_lchan_lookup() in gsm_data_shared.c.

Openbsc and osmo-bts each define their own DRSL log constant, so add an int *rc
return code argument and keep the logging part in abis_rsl.c's thin lchan_lookup()
wrapper. Incidentally, this also removes code dup for logging.

To avoid duplicate symbols, the rsl_lchan_lookup() implementation needs to be
removed from osmo-bts, so older osmo-bts git revisions will not build with
this.

Neels Hofmeyr a3d93ed2f9 jenkins.sh: remove code dup
Have a bash function to build each dependency with the same commands.  There is
a tradeoff: having each dependency build with the same function means you can't
easily tweak one of the dependencies. OTOH having a unified function means a)
more readable script, b) that we're sure not to forget some steps and c) no
need to do the same edit n times.

Set the PKG_CONFIG_PATH globally. Also a tradeoff: if a future addition
wouldn't need the same PKG_CONFIG_PATH, this would make things ugly. But that
is actually quite unlikely, and the readability improvement is substantial.

Use env variables to remember local paths. That means we always are sure to cd
to the same absolute base path, which a 'cd ..' can't guarantee; also, we avoid
possible typos for e.g. "$deps/install".

Neels Hofmeyr 832afa3f4b dyn PDCH: set lchan->state after PDCH DEACT / before PDCH ACT
Do the PDCH DE/ACT before we set the lchan->state to De-/Activation Requested.
It makes more sense semantically to change PDCH mode while the lchan is still
in NONE status. Thus slightly move some invocations:

PDCH ACT: Free the lchan before PDCH activation. Hence remove the lchan_free()
call from the rsl_rx_pdch_act_ack() code path; it used to do the PDCH
activation first and call lchan_free() in the callback.

PDCH DEACT: Set the (TCH) Activation Requested state only within
rsl_chan_activate_lchan(), after the PDCH deact is complete.

Channel allocator: don't pick channels that have a PDCH PENDING flag set, to
avoid using channels that are still in PDCH switchover (despite their state
being NONE).

The lchan_may_change_pdch() sanity checks are becoming a lot simpler.
