This also fixes a bug with log::maxsize on Windows (cannot overwrite
existing file with .old).
It simplifies the logging code a little and makes it a tad more readable.
And it adds an unreal_strftime() function to make things easy.
notices to IRCOps and in ircd.log.
See the release notes for more details.
Module coders:
You can use HOOKTYPE_CONNECT_EXTINFO to add your own additional
information as well. See get_connect_extinfo() for inspiration.
Use nvplist_add() or nvplist_add_fmt() to easily add your info
to the list.
Module coders II:
Small note: this moves the sending of the far connect notice
to /under/ HOOKTYPE_REMOTE_CONNECT instead of /above/.
When booting no log files are open yet as we have not parsed any log { }
entries yet. On *NIX we log to stderr during that stage.
On Windows it varies: when running in GUI mode we save the log to a
buffer and display it after booting in a dialog.
When running as a service on Windows we previously wrote SOME entries
to service.log, but other entries were not logged or shown anywhere.
This makes both GUI and Service-mode on windows log all ircd_log()
calls with LOG_ERROR, instead of only config_status(), config_warn()
and config_error() messages.
This also removes config_progress() which isn't used by anything.
Oh, and it also fixes a memory leak in the Windows boot code, a leak
that nobody would have noticed anyway, but still.
* There are two security groups by default: known-users and unknown-users.
See https://www.unrealircd.org/docs/Security-group_block
* New extended ban ~G:securitygroupname, with the typical usage being
MODE #chan +b ~G:unknown-users, which will ban all users from the
channel that are not identified to services and have a reputation
score below 25.
to the specified number of lines. This defaults to 1000.
This will prevent IRCOps from being flooded off ("Max SendQ exceeded")
if they list all *LINES and there are thousands.
In the newly introduced error message, after too many matches,
we also kindly point out to use filters like '/STATS gline +m *.nl'
This is the work from May 3rd.. need to commit it so i can merge the
flood protection that is related to this...
The final implementation will still need tweaking before pushed.

When connecting, use slightly different wording (and use it consistently):
"Trying to activate link with server xyz"
When the connection is lost before synced:
"Unable to link with server xyz"
When the connection is lost after fully synced (eg: minutes later):
"Lost server link to xyz"
Important small changes (other than text):
* Log ERRORs from remote servers to the log (previously only shown to ircops)
* Some link errors could have been previously suppressed due to
old code assuming other parts of the code would send or log the error
(this would be the case for an error when calling SSL/TLS write functions)
* More?
form an insecure connection. There we explain a bit on the why and how to
configure some random IRC clients.
This also silently adds support for multi-line messages in
set::plaintext-policy::user-message (for warn) and
set::plaintext-policy::oper-message (for warn and deny).
so they can fetch more history than the standard on-join history.
In the future we are also likely to implement IRCv3 CHATHISTORY
once that becomes an official specification. However, until it is
specified and until most major clients support it, several years
are likely to pass. It would be a shame to withhold channel
history to many end-users in the meantime when it takes so little
effort from us to provide an easy command.

HISTORY and CHATHISTORY.

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.

Also extban handler "is_ok" was being called with EXBTYPE_EXCEPT

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.
