It was not removing parts properly if an if didn't match,
leading to a use-after-free bug on-boot (or on rehash).
In the process I renamed config_entry_free to config_entry_free_all
since that is what it does. And I created a new config_entry_free(ce)
to free only 'ce' stuff... which is what we want from the
preprocessor.
for the user. Otherwise with post-connect SASL authentication you will
have different login information on server X compared to server Y
(the server with the user on it was always correct, though).
Also, add a function called user_account_login() which is used by both
SVSMODE/SVS2MODE and SVSLOGIN to send ACCOUNT messages to the channel.
This too was missing for SVSLOGIN (post-authentication SASL).
For this fix to be 100% effective, you need 100% UnrealIRCd 5.

logical order (1->2->3->4) rather than various helper functions first
and some random order.
session after a 15 seconds timeout. The exact timeout value can be
changed by adjusting set::sasl-timeout, which should be (quite a bit)
less than set::handshake-timeout by the way. 15<30 now, so fine.
than scattered checks - which are sometimes different - everywhere in
the source code.
Also extban handler "is_ok" was being called with EXBTYPE_EXCEPT
rather than EXBTYPE_INVEX for +I. (Not reported by anyone)
deal with servers with different set::allowed-channelchars settings:
* We reject the link if set::allowed-channelchars settings differ between
UnrealIRCd 5 servers.
* For the case where you have a mixed network consisting of UnrealIRCd 4.x
and UnrealIRCd 5.x servers we try not to desync, BUT will not allow
anyone to join the invalid channels locally. For IRCOps a message is
printed with additional information on such a failed JOIN attempt.
See https://www.unrealircd.org/docs/Set_block#set::allowed-channelchars
for the different settings, which are best and U4<->U5 advice.
