    sysmo: add L3 handle to l1prim messages
    
    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).
