The current PCU implementation has never been tested with multiple BTS
attached to it. This is due to the fact that it has been used
exclusively in an BTS co-located setup where naturally only one BTS is
present. The PCU sock protocol supports multiple BTSs in theory and we
should handle this correctly.

In osmo-bsc, there's currently 0..1 Lb links and 0..N A links, where N
is the number of MSC, but links can be shared in the underlaying stack
(struct osmo_sccp_instance), hence range 0..N of different
osmo_sccp_instance (identified by PC).
Even more, the Lb and A link can share the same underlaying stack, so
osmo-bsc can end up with only 1 struct osmo_sccp_instance shared by all
the above mentioned links in case all are configured under the same PC.
Total range A+Lb is 0..(1+N).
A struct gsm_subscriber_conn stores 2 struct sccp_instance*, one for
Lb (conn->lcs.lb.*)and one for A (conn->sccp.*).
They can actually point to the same sccp_instance or to different ones,
as explained above, depending on the configured setup. In any case, a
gsm_subscriber_conn needs 2 rb_nodes since it can hold
any of the 2 conn_ids independently (A or Lb).
The previous patch forgot to add that 2nd rb_node as well as some
initialization and release code for the Lb conn. This patch addresses
that.
When the 2nd rb_node, a problem when iterating the rbtree appears: how to
find out the "conn" pointer from the rb_node pointer, since the rb_node pointer
can be any of the 2 rb_nodes inside the struct at a different offsets.
In order to solve that problem, a new struct bscp_sccp_conn_node is
added, which holds all the relevant information used by the rbtree lookup code
in a generic way (rb_node and conn_id), plus a backpointer to the struct
bsc_gsm_subcriber it relates too.

This allows keeping the bsc_subscriber storage internals outside of main
gsm_network code, while easily allowing making the internal
implementation more complex (in order to optimize it in a follow-up
commit).
It is also nice since we get rid of uncommon procedures being used in
this code, like allocating an llist directly as a talloc context, etc.

Use the full gsm0808_chan_indicator value throughout the lchan related
structs (assignment_fsm_data, gsm_lchan, lchan_activate_info,
lchan_modify_info) instead of reducing it to the boolean
requires_voice_stream.
This is needed so we don't lose the information whether an lchan was
requested for data or speech (both need an rtp stream).
Add a new bsc_chan_ind_requires_rtp_stream function and use it in
conditionals like the previous requires_voice_stream.

Initial requests: paging requests which haven't been yet transmitted
Retrans requests: paging requests which have already been transmitted at
least once.
Until now one queue was used (llist) to store both. The initial requests
were stored at the start of the queue in FIFO order. After the last
initial requests, the retrans requests followed also in FIFO.
This ordering was used in order to prioritze scheduling of initial
paging requests over retransmit paging requests.
In the end, having both types in the same list only make code handling
the list more complex.
Hence, this patch splits the shared llist into 2 llists.

This change implements an additional channel allocation mode, which
can be employed during a TCH channel allocation for assignment.
Selection between ascending and descending order is performed
depending on pre-configured parameters:
* Uplink RxLev threshold and number of samples for averaging,
* C0 (BCCH carrier) channel load threshold.
This is useful in setups where Tx power of the RF carriers cannot be
adjusted +dynamically at run-time and thus BS Power Control cannot
be performed. In such setups the BCCH carrier is transmitting at
relatively higher power than the other RF carriers. The key idea
is to allocate channels in a smarter way, so that UEs with poor signal
would get channels on carriers with high Tx power, while UEs with good
signal could use carriers with lower Tx power.

A follow-up patch implements a special channel allocation mode, which is
only working for assignment (basically TCH selection for a voice call).
This mode cannot be employed for initial CHANNEL REQUEST or handover due
to the absence of an already established lchan.
Adding this mode to the existing VTY command syntax would be confusing:
channel allocator (ascending|desscending|dynamic)
^^^^^^^
so this patch extends the VTY syntax in a way that it becomes possible
to configure different channel allocator modes for different cases:
OsmoBSC(config-net-bts)# channel allocator mode ?
set-all Set a single mode for all variants
chan-req Channel allocation for CHANNEL REQUEST (RACH)
assignment Channel allocation for assignment
handover Channel allocation for handover
The old command syntax, which is basically 'set-all', is kept for
backwards compatibility, but marked as deprecated.

From the nature of the lchan_activate_info.tsc_set and .tsc, it is easy
to forget to set tsc_set,tsc = -1 to use default TSC Set and TSC values.
Handover code is one such instance that forgets to set -1.
Change the semantics of tsc_set and tsc so that this kind of error can
not happen again as easily: use a separate bool to flag whether to use
the default config or explicit values.

Allow resetting the BSSMAP link from VTY, for BSC_Tests.ttcn.
In the field, detecting that an MSC is lost is done by getting three
connection failures in a row. For the BSC_Tests, it is easier to just
provide a VTY command to reset an MSC's link status.
I want to add tests that verify the stat items reflecting the MSC
connection status. To be able to run a test expecting fewer connected
MSC after a test that launched more MSCs requires the links to be reset.
