value should now be one of EX_*:
EX_DENY : disallowed, except for oper override
EX_ALLOW : allowed
EX_ALWAYS_DENY : disallowed, even in case of operoverride (eg for
operlevel modes like +A).
Note that it's backward compatible since TRUE/EX_ALLOW=1 and FALSE/EX_DENY=0.
- Fixed a few bugs with oper override & extended chanmodes, for example
chanmode +T could not be set by a globop w/can_override and non-+hoaq.
- Changed some useless stuff.
- Enabled EXTCMODE by default, I presume it's stable but can't promise anything.
- Module coders: changed 'allowed' callback function for umodes&snomasks,
from 'aClient *sptr' to 'aClient *sptr, int what'.
'what' will be MODE_ADD if trying to add and MODE_DEL if trying to remove.
