    dyn PDCH: lc15: complete for litecell15-bts: implement bts_model_ts_*()
    
    Analogous to 63b296bdd9a25134ee61ce6f269750e796a8bfca on osmo-bts-sysmo.
    
    Implement bts_model_ts_disconnect() by sending an MphDisconnect message to L1.
    Pass a disconnect callback to invoke dyn_pdch_ts_disconnected() in
    common/rsl.c.
    
    Implement bts_model_ts_connect() by calling ts_connect_as(). Pass a connect cb
    to invoke dyn_pdch_connected() in common/rsl.c.

    dyn PDCH: lc15: add ts_connect_as(), absorbing ts_connect() guts
    
    Analogous to 294fbe104b9fb12f06f7cebe68a4b7a6ed28d5ef on osmo-bts-sysmo.
    
    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.

    dyn PDCH: lc15: chan_nr_by_sapi(): handle TCH/F_PDCH according to ts->flags
    
    Analogous to 0d10f0e482cdd50acc916e75a8b3ba1beb94227c on osmo-bts-sysmo.
    
    According to the PDCH Active flag, handle a TS as TCH/F or PDCH.

    lc15: add L3 handle to l1prim messages
    
    Analogous to 7158c2ed082eaca6063a501e490e8d3c3b181560 in osmo-bts-sysmo.
    
    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.

commit 7d210770a9ef5d2e30641319dc9b304b79e80f72

    fix lc15 build: put src/common/libbts.a left of -losmogsm
    
    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.
