Change in osmocom-bb[master]: trxcon: rework trxcon_fsm, move into a separate file

by fixeria

Attention is currently required from: osmith, laforge, pespin. Hello osmith, Jenkins Builder, laforge, pespin, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/osmocom-bb/+/28809 to look at the new patch set (#4). Change subject: trxcon: rework trxcon_fsm, move into a separate file ...................................................................... trxcon: rework trxcon_fsm, move into a separate file The original trxcon_fsm I wrote back in 2017 [1] was more like a boolean flag, as there were only two states: IDLE and MANAGED. Not surprising, given that until recently handling of multiple L1CTL connections was not supported. Now that we have this implemented, lifetime of a trxcon_fsm instance is limited by lifetime of a L1CTL connection, what renders the FSM useless. This change removes the old 'boolean' trxcon_fsm and introduces the new one, which will allows us to abstract the L1CTL interface from the TRXC/TRXD interfaces, as well as the scheduler. The new FSM will also simplify development of the RLC/MAC layer for GPRS.
