just like client->user is set if the client is a user.
Rename client->srvptr to client->uplink: this is the uplink that the client
is connected to. If the client is a user then it is set to the server that
the client is connected to, if the client is a server then it is set to the
server that the server is connected to (the.. tadah.. uplink).
For local clients it is always set to &me.
This broke SASL services autodetection and also sasl=x,y,z in CAP.

Of course the easiest solution would be just to set .remote_write=1
for this, which is what I've just done for the 5.2.1.1 release.
But there seems to be a pattern here. When a server wants to write
its own object (irc1.example.net writing to the MD object of
irc1.example.net) we have the problem that that object is both
"our client" and from the other server POV it is "themselves".
On one hand you may want to allow that (eg for 'saslmechlist'), on
the other hand a server writing its own 'certfp' sounds like a bad
idea in principle.
So we now add a new option for the 'self' case and make some MD
objects use it. In fact, in the core we now have zero MD objects
using remote_write. We keep the option available though, for example
for k4be's geoip modules and possibly future features.
Module API change:
* .self_write added which allows a server to write to its own object
(irc1.example.net writing to the MD object of irc1.example.net)
* .remote_write still exists too if you want to allow remote servers
to write to your own objects
* Note that in all cases, servers can always write to their own
(child) client objects.
Changes:
* The link-security MD changed from .remote_write=1 to .self_write=1
* The salmechslist MD now has .self_write=1, this fixes the actual bug
This so I - and others - don't constantly have to wonder whether the client
is called sptr, cptr or acptr in a simple routine.

Couldn't just mass-replace of course since there are places where there
are multiple clients involved. So had to check each function.
Also renamed some 'acptr' to 'target' and such.
I will write a page with new style rules later.. but in short if there is
only 1 client involved it will now be called 'client'.
code changes in UnrealIRCd itself:
1) Clients are no longer freed directly by exit_client. Most fields
are freed, but 'sptr' itself is not, so you can use IsDead() on it.
2) exit_client now returns void rather than int
3) ALL command functions return void rather than int.
Of course this also affects do_cmd, command overrides, etc.
This is a direct consequence of the removal of 'cptr' earlier, as that
was used to signal certain things that are now no longer possible
(and it raises the question if things were always correctly signaled
in the first place, so may fix some bugs).
It also makes the code more resillient against cases where you forgot
to check if the client was freed. Still, you are encouraged to do an
IsDead(sptr) if you are calling functions that may kill clients,
such as command functions or things that may use spamfilter.
More changes will follow, such as the removal of FLUSH_BUFFER.
which specifies the time in milliseconds rather than seconds. This
allows for additional precision, or at least multiple calls per second.
The minimum allowed every_msec value is 100 at this time.
The prototype is now: EventAdd(Module *module, char *name,
vFP event, void *data, long every_msec, int count);
MOD_UNLOAD. And MOD_HEADER(xyz) is now MOD_HEADER even without ()
since this isn't a function, really.
To make things understandable I added the following to the
developer section of the release notes:
* The module header is now as follows:
ModuleHeader MOD_HEADER
= {
"nameofmodule",
"5.0",
"Some description",
"Name of Author",
"unrealircd-5",
};
There's a new author field, the version must start with a digit,
and also the name of the module must match the loadmodule name.
So for example third/funmod must also be named third/funmod.
* The MOD_TEST, MOD_INIT, MOD_LOAD and MOD_UNLOAD functions no longer
take a name argument. So: MOD_INIT(mymod) is now MOD_INIT()
aChannel to Channel, and some more. Third party module coders will
love this. But.. it makes things more logical and the doxygen output
will look more clean and logical as well.
(More changes will follow)
and remove old dependency field (never used, was always NULL,
broken since 3.2.x)
I'll add some constraints later on things like names and versions.
IOTW: more changes to follow, don't mass update your own mods yet.
For example, msgid / message-ids is not a CAP, while server-time is.
There mere fact of something being in CAP or not shouldn't cause
something to be in different directories ;).
