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.

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.

Incorrect regular expression used by default to authorize all

It is particularly interesting to see whether a given lchan type is allocated
on a dynamic timeslot.

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.

We keep some random snippets of documentation here, but manuals are now
generally kept in osmo-gsm-manuals.git. Particularly the GSUP, OAP and
control interface are documented more extensively there.
To avoid having two sets of (diverging) documentation, let's remove it
from the openbsc.git repository.

Skip PDCH activation if the GPRS mode is 'none' at:
* TCH/F_PDCH init after OML Enable (dyn_pdch_init())
* after TCH/F_PDCH is released, in TCH/F mode
* in the T3111 error timer callback after a TCH/F_PDCH was released in error
state
Assert the GPRS mode in rsl_ipacc_pdch_activate() to make sure all callers
check the GPRS mode.

The A&C reference number specified in 3GPP TS 24.008 § 10.5.5.19
identifies particular request sent by network with the related response
sent by MS. The value transparently copied from request to response by
MS: the spec do not specify what exactly should be in there so we use
rand() to decrease chance for collisions.
Note: variable named 'rand' clashes with standard function rand() so it
was renamed.

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".

Without this commit it is possible that osmux is disabled again on links with
high jitter. This happens when an MGCP response without X-Osmux header is
received before the NAT receives an Osmux dummy frame from the other side.

Previously if subscriber was automatically created it got assigned
random MSISDN number. Make it optional (defaulting to previous behavior)
by adding following:
* new optional no-extension argument for subscriber-create-on-demand vty
command
* db unit tests
* vty test
Note: using the db made with new code might result in subscribers with
empty extension. Such subscribers cannot be deleted using old
code. Make sure not to mix db versions or manually fix it by editing
sqlite with external program.

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.

Set and clear pending flags on the TS according to PDCH de-/activation.
This will allow changing the time we set the channel state to after PDCH
DEACT and before PDCH ACT, in a subsequent commit.
Also add a sanity check on whether we're sending conflicting or superfluous
PDCH de-/activations on the same TS.
