According to 3GPP TS 44.060, section 12.24, GPRS Cell Options IE
contains two parameters related to 11 bit Access Burst support:
- ACCESS_BURST_TYPE - whether the 8 or 11 bit format shall be
used in the PACKET CHANNEL REQUEST message, the PTCCH/U block,
PACKET CONTROL ACKNOWLEDGMENT and the PS HANDOVER ACCESS
messages on the PRACH (if present).
- EGPRS_PACKET_CHANNEL_REQUEST - whether EGPRS capable MSs shall
use EGPRS PACKET CHANNEL REQUEST message for Uplink TBF
establishment on the RACH or on the PRACH (if present).
The VTY option 'gprs 11bit_rach_support_for_egprs' actually controls
the second parameter - EGPRS_PACKET_CHANNEL_REQUEST, though it may
be hard to understand this from its name and description.
This patch is actually a group of tightly related changes:
- deprecate 'gprs 11bit_rach_support_for_egprs (0|1)':
- update its description to avoid any possible confusion,
- print a warning if it's used in non-EGPRS mode,
- print a warning if it's still used;
- introduce '[no] gprs egprs-packet-channel-request':
- ensure that it can only set / printed in the EGPRS mode;
- take a chance to clean-up / rename the related struct members:
- 'supports_egprs_11bit_rach' -> bool 'egprs_pkt_chan_request',
- remove 'supports_egprs_11bit_rach' from 'gprs_cell_options'
because we already have 'ext_info.use_egprs_p_ch_req' there.

As pointed out at https://github.com/libexpat/libexpat/issues/312
libtool does not play nice with clang sanitizer builds at all.
For those builds LD shoud be set to clang too (and LDFLAGS needs the
sanitizer flags as well), because the clang compiler driver knows how
linking to the sanitizer libs works, but then at a later stage libtool
fails to actually produce the shared libraries and the build fails. This
is fixed by this patch.
Addtionally LD_LIBRARY_PATH has no effect on conftest runs during
configure time, so the rpath needs to be set to the asan library path to
ensure the configure run does not fail due to a missing asan library,
i.e.:
SANS='-fsanitize=memory -fsanitize-recover=all -shared-libsan'
export CC=clang-10
ASANPATH=$(dirname `$CC -print-file-name=libclang_rt.asan-x86_64.so`)
export LDFLAGS="-Wl,-rpath,$ASANPATH $SANS $LDFLAGS"

This logging category has been removed in [1], what caused test
case execution failures on our Jenkins (since build #930). The
problem is that configuration files may still contain this
category in 'logging' section (see [2], [3], [4]), and
osmo-bsc would refuse to start because of that.

If, as before this patch we call initCDKScreen() before
attempting to bind the socket, then the socket bind fails,
we exit and the terminal needs a reset.
Attempt to open the socket before initCDKScreen()
so we don't end up with a messed up terminal if the socket
call fails.

The measurement tools use libosmocore socket functions that will
use logging if the socket cannot be opened, but the tools did
not initialise logging, resulting in
Assert failed osmo_log_info logging.c:235

Initialise logging so that we get a nicer and more informative
message, such as:

Separate raw input parsing from handling the failure report. A follow-up
patch will use the new parsing function to print saved failure reports
to the VTY.
While at it, put struct tlv_parsed inside struct nm_fail_rep_signal_data
instead of a pointer, so we don't need an additional alloc. Also add
error handling to the abis_nm_tlv_parse() call.

OM2000 is not only used for the venerable RBS2000 family, but also
for the more modern RBS6000 family, specifically the DUG 20 GSM
baseband unit.
In RBS6000, there are some protocol extensions which are not yet fully
understood. However, we are understanding some bits around the MCTR
(multi carrier transceiver?), a new MO that appears to be present for
every physical RUS (Radio Unit) attached to the DUG 20.
Let's add what we have learned so far.
Thanks to Sylvain Munaut for his help with this.

Calling osmo_tdef_vty_write() twice: with and without the 'timer '
prefix definitely looks like a bug. After setting any timer to a
custom (non-default) value, config_write_net() would generate an
incorrect configuration file:
$ osmo-bsc -c /tmp/osmo-bsc.cfg
There is no such command.

Replace python 2 code using pychart to draw a graph in
osmux-reference.adoc with the generated svg file. The upstream of
pychart is dead, there is no python 3 version, and python 2 is EOL at
the end of 2019.
This is the only time we ever made use of pychart in osmo-gsm-manuals,
so with this change, we can just drop the dependency.
I've generated the chart by saving the python code in chart.py, then:
$ ./chart.py --format=svg --font-size=3 > chart.svg

After sending of NM_MT_IPACC_RSL_CONNECT message, we start a timer,
and stop it on receipt of NM_MT_IPACC_RSL_CONNECT_{ACK,NACK}. When
running a multi-trx setup, one can see the following warnings:
DRSL NOTICE abis_nm.c:2852 (bts=0,trx=1) RSL connection request timed out
DRSL NOTICE abis_nm.c:2852 (bts=0,trx=2) RSL connection request timed out
even despite NM_MT_IPACC_RSL_CONNECT is actually being acknowledged.
The problem is in abis_nm_rx_ipacc(): we cannot just use sign_link->trx,
because the message itself was received over the OML link, so this
pointer always gives us C0/TRX0. Instead, we must find a TRX by its
number from the FOH header using gsm_bts_trx_by_nr().

Lots of times, the MS power class is unknown until after the first
channel has been activated, at which point the MS power class is
received in messages such as LU update or CM Service Requet.
Since the MS Power level is sent upon CHAN ACT, the only way to
communicate the change of maximum MS Power (based on MS power class)
after CHAN ACT is to send a MS Power Control msg. Let's do that.
