Move opername and privset storage to struct User, so it can exist for
remote opers.
On /oper and when bursting opers, send:
:foo OPER opername privset
which sets foo's opername and privset. The contents of the privset on
remote servers come from the remote server's config, so the potential
for confusion exists if these do not match.
If an oper's privset does not exist on a server that sees it, it will
complain, but create a placeholder privset. If the privset is created by
a rehash, this will be reflected properly.
/privs is udpated to take an optional argument, the server to query, and
is now local by default:
/privs [[nick_or_server] nick]
Purge a lot of really old and obsolete documents, and merge some together
where possible. Lots of efnet docs and the old ircd-ratbox manpage (lol)
was purged.
Reorganise everything nice and neatly as possible. Things describing
features can be found in features/, and some more technical documents
were moved to techinical/.
Old credits file was consolidated into credits-past.txt, and a reference
was added to it in the credits.
The code to send each channel mode only to servers supporting it was
broken a while ago and was not very useful anyway. Therefore, require
all connecting servers to support all standard channel modes.
