Correct the too short padding I introduced in the commit
a55b166c6c. The result needs to
be 121 and not 120. Add static asserts to make sure it does
not happen again.

Back in January in commit 634c3e4648 we
changed the executable name from 'sysmobts' to 'osmo-bts-sysmo', which
is a change that has not been propagated to the contributed screenrc and
systemd init files.

time

The function would currently only be called in cases where one of the if
branches catches on, but for safety's and clarity's sake, don't ts_connect
using as_pchan if no reconnect is pending.

Implement bts_model_ts_disconnect() by sending an MphDisconnect message to L1.
Pass a disconnect callback to invoke dyn_pdch_ts_disconnected() in

For upcoming dyn PDCH switching, I want to be able to set the pchan dynamically
upon ts_connect() and not continue with OPSTART ACK, but with the dyn PDCH.
Thus recoin ts_connect(ts) to ts_connect_as(ts, pchan, cb) and leave
ts_connect() as a thin wrapper to leave init code unchanged.

Place a layer 3 handle into GSM L1 messages to better match up confirmations to
respective requests. This handle is a uint32_t transparently returned in the
confirmation messages, so a match-up is easy to add.
So far, a GSM L1 confirmation message received for a preceding L1 Request was
matched only by the prim_id. That meant that only one instance of the same
primitive could be waiting for a confirmation at any given time, or the
responses would get mixed up: the struct wait_l1_conf instances entered into
the fl1h->wlc_list queue would be returned to a possibly mismatching
confirmation handler. (Seen during testing of dyn pdch switching.)
Send the hLayer3 handle out via prim_init(), using new static functions to
produce handles on different scopes:
* l1p_handle_for_trx()
* l1p_handle_for_ts()
* l1p_handle_for_lchan()
(These could possibly move to a more general .h/.c file later.)
Remember the hLayer3 handle in
* struct wait_l1_conf.
Match the incoming confirmations' and stored hLayer3 handles up in, and remove
a now obsolete comment from:
* is_prim_compat()
Since the hLayer3 members are at different byte offsets in
GsmL1_Prim_t.u.*, use large switch statements to set/get the value:
* In prim_init(), extend existing switch statement to set in GsmL1_Prim_t.
* Add l1p_get_hLayer3() to retrieve from GsmL1_Prim_t (could possibly move to a
more general .h/.c file later).
Note that some messages are already using the hLayer3 handle, and will
overwrite it after calling prim_init(), so those are not affected.

When switching to the gsm_chan_t_names string list from libosmogsm,
libosmogsm actually became a dependency of the local libbts.a.
The breaking change is in openbsc.git 29048b2a80b5865ffc41fa4401113c5826227e23
and came in here because gsm_data_shared.h is included from openbsc.

React on IPAC PDCH ACT and DEACT messages and invoke the PCU and bts_model_ts_*
APIs to effect switchover. The dyn PDCH interaction is described in the comment
to rsl_rx_dyn_pdch(), the main entry point for PDCH switchover.
In case the bts_model_ts_* are not implemented (or return other errors),
reply with an IPAC PDCH ACT/DEACT NACK.
Add callbacks that mark steps in the PDCH switchover process,
dyn_pdch_ts_disconnected(), dyn_pdch_ts_connected() and dyn_pdch_complete().
Add hooks in l1sap.c on channel activation and release confirmation, to call
dyn PDCH callbacks.
BTS dyn PDCH implementations should invoke dyn_pdch_ts_disconnected() and
dyn_pdch_ts_connected() when bts_model_ts_disconnect() or
bts_model_ts_connect() are called, respectively. (upcoming for sysmoBTS)

Introduce a static function to encapsulate the decision whether a TS is
used for PDCH. Depending on the ts->flags, handle a TCH/F_PDCH TS exactly like
a standard PDCH TS.

Enhance bts_model_ API in preparation of dyn PDCH switching. These will be used
to re-connect a TCH/F_PDCH TS in a different mode: either as TCH/F or as PDCH.
All implementations so far return -ENOTSUP, and thus will cause a IPAC PDCH ACT
or DEACT *NACK* to be sent to the BSC as soon as these messages are handled.
Also add stubs in tests.

It is cosmetic since the 'default:' case already caught TCH_F_PDCH, but it's

Before, only standard ABIS RSL message names were logged, add ip.access
specific ones.
The IPAC_PDCH_ACT and _DEACT msgs are received with an ABIS_RSL_MDISC_DED_CHAN
discriminator, and not with _MDISC_IPACCESS like the others. Thus rsl_rx_dchan()
should be able to log ip.access message types properly.
