Change subject: Replace ul_ass_state with osmocom FSM

Patch Set 4:

File src/tbf.cpp: 
PS4, Line 767: s X2000,
> why was this removed? (maybe it makes sense to do this in a separate commit and explain it there?)
Timer X2000 is moved inside the new FSM, so it's not handled by this pcu-specific mechansim anymore, but using usual osmocom FSM timer callback. 
PS4, Line 967: 	osmo_fsm_inst_update_id(tbf->, buf);
> Why give two separate FSMs the same ID, wouldn't it be better to add some kind of suffix that differ […]
No need for that, the name of the FSM (which is different for the 2 types) always show up next to the id, so it's totally fine. Having same ID actually helps in quickly relating different FSMs to same TBF. 
File src/tbf_ul_ass_fsm.h: 
PS4, Line 32: 	TBF_UL_ASS_EV_CREATE_RLCMAC_MSG, /* Scheduler wants to gen+Tx the Ass (rej): data=tbf_ul_ass_ev_create_rlcmac_msg_ctx */
> (line length)
I prefer keeping comment in one line even if it's a few chars too long. 
PS4, Line 52: fi
> (Same for "replace dl_ass_state with osmocom FSM" patch)
no, the comment is fine. "the_pcu" is actually a global variable which always exists :) 
File src/tbf_ul_ass_fsm.c: 
PS4, Line 306: bool tbf_ul_ass_rts(const struct gprs_rlcmac_tbf* tbf)
> assuming rts means.... ready to send? would be good to add it as comment […]
It's common in different osmocom projects like osmo-bts. I'm already using same sort of naming for other FSMs such as the NACC one. These functions are basically used from the scheduler to know whether a related message is waiting to be preparted and sent.
