Use the proper type that can handle the entire range of MSC numbers we
allow on the VTY, we have:
#define MSC_NR_RANGE "<0-1000>"
Before this patch, MSC pool round robin would glitch around for any
'msc' numbers 'msc 256' thru 'msc 1000'.

In abis_rsl_rx_rll(), we do the following header length check -- quick
challenge, can you spot the two bugs hidden here?
struct abis_rsl_rll_hdr *rllh;
if (msgb_l2len(msg) >
sizeof(struct abis_rsl_common_hdr) + sizeof(*rllh))
msg->l3h = &rllh->data[3];
Fix these bugs:
- struct abis_rsl_common_hdr is already included as the first member of
abis_rsl_rll_hdr, no need to add that.
- We are going to be accessing rrlh->data[3], so we must check for at
least sizeof(*rllh) + 4.

If power saving is enabled for a BTS, it should remain enabled even
if the BTS is restarted for whatever reason. This persistence can be
achieved by re-sending the configured power reduction value whenever
the BTS NM FSM enters the ENABLED state again (i.e. reconnects).
Separate gsm_bts_send_c0_power_red() from gsm_bts_set_c0_power_red()
and call the former from st_op_enabled_on_enter(). All we need to do
is to send the value that was configured before, per-timeslot power
reduction limits remain and need not to be updated.
Take a chance to move logging from BTS specific to the generic code.

EUTRAN neighbors can be deleted using the following command:
$ osmo_ctrl.py \
-d 127.0.0.1 -p 4249 \
-s "bts.0.si2quater-neighbor-list.del.earfcn" EARFCN
UTRAN neighbors can be deleted using the following command:

This commit implements only deletion, implementing the add command
would require slightly more effort (lots of manual string parsing),
so it's left as a TODO for later.

NSVC local port 0 is actually a valid value, which tells the PCU to
pick a random port for bind()ing. It was supported before 315af2f9e,
but now osmo-bsc would simply ignore NSVCs with 'local udp port 0'
and leave the respective MOs unconfigured in the BTS.

* osmo-bsc currently does not support adding multile EARFCNs
with different thresh/prio/qrxlv parameter values;
* adding an EARFCN which already exists creates a duplicate;
* adding an UARFCN which already exists fails;
* adding UARFCN=0 fails.

Running OsmoBSC, Configure primary Links that enables users to get an
idea where exactly the BSC co-located PCU has its place in the RAN
infrastructure and which links it is connected with. Also give a short
example how to setup the unix domain socket path.
A more detailed description, especially about the timeslot configuration

The situation apparently is conn->lchan == NULL (primary lchan is gone),
but Assignment has just concluded. Apparently an unexpected / orthogonal
event has interrupted operations.
During assignment_success(), do not assume that conn->lchan is still
present. This should normally be true, but if not, fail the assignment
procedure instead of crashing osmo-bsc.
