contrib/fsm-to-dot: less false positives on event parsing
Do some more mad hacking to only detect event triggers if event names actually
appear in if() or case: statements. Also combine events in consecutive 'case'
statements.
When will this madness stop?

contrib/fsm-to-dot: mark arrows that feed events
Most arrows draw state transitions, but some want to show that an event is
delivered to a state. Mark those with a "halfopen" arrow head.

contrib/fsm-to-dot: add default edge label '-'
When some edges have no label, it is sometimes hard to interpret which label
belongs to which edge. Adding a '-' default label clarifies the edge
labeling.

contrib/fsm-to-dot: warn and draw unallowed state transitions
Hacked as it is, fsm-to-dot is capable of detecting action functions
transitioning to states that are not allowed according to the FSM definition
struct.
Draw those in red and output a warning.
Found these osmo-bsc gscon errors with this patch:
ERROR: gscon_fsm_active() triggers a transition to ST_WAIT_HO_COMPL, but this is not
allowed by the FSM definition
ERROR: gscon_fsm_wait_ho_compl() triggers a transition to ST_WAIT_MDCX_BTS_HO, but
this is not allowed by the FSM definition

contrib/fsm-to-dot: don't match on event names in comments
Strip comments from function bodies before matching on event names.
In osmo-bsc's gscon FSM, there often are event names in comments. The naive
parsing of fsm-to-dot.py mistakes these as events causing state transitions,
but the comments are just explaining how states interact.
Makes me reconsider parsing the C with clang instead, but I got away with a
dirty hack once more.

contrib/fsm-to-dot: allow transition from and to the same state
In osmo-bsc's new gscon FSM, there is an osmo_fsm_inst_state_chg() from
ST_ACTIVE to ST_ACTIVE. Avoid an exception triggering on this simple fact.
