Move the requirement checks within the respective plugin cmakefile.
Use REQUIRED instead of the manual FOUND check and error handling.
Note: the tcl check was only moved, since using REQUIRED explodes in
CI.

At the moment, building WeeChat triggers several thousand -Wstrict-prototypes
diagnostics. This is due to its source code using an empty argument list for
functions and function pointers that take no arguments, instead of explicitly
declaring that they take no arguments by using a void list.
This commit replaces all empty argument lists with a void list.
Note that Ruby's headers also suffer the same problem, which WeeChat can't
do anything to fix. Thus, building WeeChat with the Ruby plugin enabled
will still issue approximately 30 such diagnostics.
This should definitely fix the crash with Python 3.12, even when scripts are
auto-loaded (the previous fix was working only when the scripts are loaded
manually).
This fixes an issue with IRC URL given on command line when it starts with
`ircs://` or `irc6://`: the server is not created at all (only `irc://` works
fine).
The callback_read and callback_create_option functions in the scripting
APIs always get the value as a string, never as null. This means that if
the value is null, there is no way for the script to distinguish this
from an empty string for string options. This makes it impossible to
properly make options with fallback values, like the irc server and
server_default options, as far as I can see.
All the scripting languages except Tcl use that language's equivalent
for null. For JavaScript which has both null and undefined, null is
used. For Tcl, the magic null string defined in commit 197a7a01e is used
and the documentation is updated to describe that.
I tested this with these scripts:
https://gist.github.com/trygveaa/2d49c609addf9773d2ed16e15d1e3447
You can load all of those scripts and see the result with this command
(assuming you have the scripts in the current directory):
weechat -t -r "/filter add script * * script; /script load $(echo script_config.*)"
This was preventing the PHP plugin from working if PHP was compiled
with `--enable-debug`. With this patch, `--enable-debug` builds of
PHP should work.
