This update added new revisions after undoing existing revisions.  That is
to say, the old revision is not a strict subset of the new revision.  This
situation occurs when you --force push a change and generate a repository
containing something like this:
* -- * -- B -- O -- O -- O (b6ac607ca4c27654d7296f51c5ce91667a27b7c7)
            \
             N -- N -- N (5be478b7574fc9152a4df2eb066abde001769b0b)
When this happens we assume that you've already had alert emails for all
of the O revisions, and so we here report only the revisions in the N
branch from the common base, B.
Those revisions listed above that are new to this repository have
not appeared on any other notification email; so we list those
revisions in full, below.

dyn TS: split dyn_pdch_init() for new dyn type and rename
Init both TCH/F_PDCH and TCH/F_TCH/H_PDCH via dyn_ts_init(), which
    refactors dyn_pdch_init().
Make dyn_ts_switchover_start from abis_rsl.c public in abis_rsl.h, so we can
    start the initial switchover to PDCH from dyn_ts_init(); in abis_rsl.h include
    gsm_utils.h for enum gsm_phys_chan_config.

dyn TS: implement pchan switchover logic
In struct gsm_lchan, add dyn.rqd_ref and dyn.rqd_ta. These save the Channel
    Requested details across the PDCH deactivation dance.
abis_rsl.c: add static functions:
* dyn_ts_switchover*() for the various stages of switchover between pchans.
* pchan_for_lchant() to derive the desired pchan from the lchan type that was
      set during lchan_alloc().
* rsl_chan_activate_lchan_as_pdch() to compose the simpler RSL CHAN ACT message
      without introducing numerous special cases to the normal RSL CHAN ACT code.
In rsl_chan_activate_lchan(), detect and initiate required pchan switchovers if
    requested pchan on a dyn TS differs.
In rsl_rx_rf_chan_rel_ack(), initiate or continue pchan switchovers after a
    channel was released.
In rsl_rx_chan_act_ack(), notice that a switchover is complete.

dyn TS: add ts_subslots()
abis_rsl.c will need to know the number of subslots per pchan, to verify that
    all lchans are free before dyn TS switchover.
The subslots_per_pchan[] array is static to lchan_alloc.c, and since we need a
    check for dyn TS anyway, add public ts_subslots() to lchan_alloc.c, which also
    checks the current dyn pchan type.

dyn TS: enhance channel allocator for dynamic TS
Change _lc_find_bts() to _lc_dyn_find_bts() with added dyn_as_pchan arg to
    pass exactly as which pchan we'd like to allocate on a dynamic TS. Add
    _lc_find_bts() as wrapper so non-dynamic-TS callers remain unchanged.
Also add dyn_as_pchan arg to _lc_find_trx() (not renaming to dyn and wrapping
    because there is only one caller).
Implement dynamic allocator logic in _lc_find_trx() and lchan_alloc().
A returned dynamic channel still needs to be switched to the proper mode, which
    will follow in another commit.
Replace a fixme comment with a normal comment in subslots_per_pchan[], because
    handling of dynamic TS is now defined.

dyn TS: rsl *2chan_nr(): handle TCH/F_TCH/H_PDCH
In gsm_lchan2chan_nr() use the current pchan type.
In gsm_lchan_as_pchan2chan_nr(), add the special case of non-standard cbits for
    activating PDCH on a TCH/F_TCH/H_PDCH dyn TS. This way, gsm_pchan2chan_nr()
    conforms to the standard and does not need access to a ts struct.

dyn TS: gsm_lchan2chan_nr(): decouple from ts->pchan
For upcoming dynamic TS, the pchan choice for RSL De-/Activation is not
    trivial. So in order to pass the desired pchan to generate the RSL chan_nr,
    introduce gsm_lchan_as_pchan2chan_nr().
To avoid code dup, this requires decoupling the gsm_ts2chan_nr() pchan from the
    actual ts struct, so refactor gsm_ts2chan_nr() to gsm_pchan2chan_nr() with
    explicit pchan, ts_nr and lchan_nr arguments.
