protocol/inspircd: Send CHGHOST via ENCAP when setting the host of unregistered users logged in via SASL
protocol/inspircd: Skip sending CHGHOST if the host is not meant to be changed

If the host equals "*" then no change is necessary
protocol/inspircd: Remove dead code from inspircd_svslogin_sts()

InspIRCd is always using uids so the check is always false
chanserv/op: allow people with CA_AUTOOP to op themselves

This follows commit 30fe519c6dec7fc6 which did the same with CA_AUTOVOICE.
alis: automatically surround topic matches with wildcards

Searching by exact match is literally _never_ useful for topics. Prefer
usability over compatibility with a decades-old IRCnet service.
alis: remove forgotten debug message
alis: auto-add wildcards to the channel name, too

But exempt searches for an exact channel name, e.g. "LIST #foo".
alis: retab
alis: move query.mask parsing to parse_alis()
alis: fix a memory leak I introduced
nickserv/list: always pass a pointer to the arg

(though Atilla is saying the handlers ignore it anyway)
Merge pull request #351 from attilamolnar/master+inspircd-sasl-chghost

protocol/inspircd: Set vhost properly for users logging in via SASL
saslserv/main: accept grouped nicknames

Due to popular request, finish what was started by ff19f558a24d.
Can't say I like this, but it was easy to do, and I guess I should
continue with the "usability" line anyway.
saslserv/main: _actually_ accept grouped nicknames

I forgot to actually test with NICK/USER/CAP END, so never noticed the
"account ?? dropped" error. Sigh.
saslserv/main: fix some things I broke with the authzid stuff

I've no idea why I added it. Nothing needs it and all it does is break
things. I should just revert it for 7.2 I guess.
core: time_ago(): skip seconds for >1w durations

Make the output shorter. Once it reaches months or even years,
one-second precision isn't that useful anymore.
chanserv/flags: clean up do_list()
chanserv/flags: show absolute timestamp as well
core: time_ago(): make output much shorter (1d 2h 3m 4s)
