For some reasons, OsmoTRX sends 158-byte long sequences on DATA
interface, where the latest two bytes aren't used.

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.

This is the second side of the 'OsmocomBB <-> SDR' bridge.
Most of source code taken from the OsmoBTS project.
