host/trxcon: initial release of transceiver interface This is the second side of the 'OsmocomBB <-> SDR' bridge. Most of source code taken from the OsmoBTS project. Change-Id: I96fa3ada05d010f31af419a4950fd8ae2b62ef34

host/trxcon: integrate osmo-fsm framework This change introduces the following state machines: - trxcon_app_fsm - main application state machine. This state machine handles different events, raised from program modules (such as trx_if.c or l1ctl.c). - l1ctl_link_fsm - L1CTL server state machine. - trx_interface_fsm - TRX interface state machine. The program modules (such as trx_if.c or l1ctl.c) should be as much independent from each other as possible. In other words, one module should not call methods from another, e.g. L1CTL handlers are not able to send any command to transceiver directly. Instead of that, they should use shared event set to notify the main state machine about something. Depending on current state and received event, main state machine 'decides' what to do. This approach would allow to easily reuse the source code almost 'as is' anywhere outside the project. Change-Id: I7ee6fc891abe5f775f5b7ebbf093181a97950dea

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() Change-Id: I6d0f437a68f0eb4e22bf635bf899b08673571085
