host/trxcon/scheduler: implement management functions

This change introduces some new functions to configure
TDMA scheduler. They can be grouped as follows:

  - Scheduler management functions
    - sched_trx_init()
    - sched_trx_reset()
    - sched_trx_shutdown()

  - Timeslot management functions
    - sched_trx_add_ts()
    - sched_trx_find_ts()
    - sched_trx_del_ts()
    - sched_trx_reset_ts()
    - sched_trx_configure_ts()

  - Logical channel management functions
    - sched_trx_activate_lchan()
    - sched_trx_deactivate_lchan()
    - sched_trx_find_lchan()
