Add "CAP chghost" support. Internal recode of userhost changes.

Browse Source 
Fix force-rejoin not working if doing SVSMODE -x/+x (Koragg, #5015).

Note to module coders:
Please use the following procedure in case of an user/host change:
* userhost_save_current(acptr);
* << change username or hostname here (or both) >>
* userhost_changed(acptr);
This function will take care of notifying other clients about
the userhost change, such as doing PART+JOIN+MODE if force-rejoin
is enabled, and sending :xx CHGHOST user host messages to
"CAP chghost" capable clients.

Also, small note to everyone:
If force-rejoin is enabled we will not send the PART+JOIN+MODE to
"CAP chghost" capable clients. Doing so is just a hack to notify
people of a userhost change. "CAP chghost" users can thus benefit
from the reduced noise in this respect.
