libosmocore[master]: fsm: Add a function to change the FSM instance ID later

[daniel]

Patch Set 1:

(2 comments)

Patch Set 2 has also restored the ability for an fsm instance to have NULL passed as an id. I'm not sure if that was used before, but this way the behaviour is unchanged.

https://gerrit.osmocom.org/#/c/6316/1/include/osmocom/core/fsm.h
File include/osmocom/core/fsm.h:

Line 90: 	char *id;
> hm. We cannot change a "const char *" pointer?  I always thought it states 
The issue here is the talloc_free() parameter being non-const.

fsm.c:214:16: warning: passing argument 1 of ‘_talloc_free’ discards ‘const’ qualifier from pointer target type [-Wdiscarded-qualifiers]
    talloc_free(fi->id);

I'll cast the argument to a void* in that call.

Line 205: bool osmo_fsm_inst_update_id(struct osmo_fsm_inst *fi, const char *id)
> in general we return 0 on success and negative on error.  Only predicate-ty
Done
