silc-client: Add variant for irssi plugin

[arthur@…]

silc-client can be complied as a plugin for irssi. To enable this I altered the port file to add to the configure options:

                        --disable-asm \
+                        --with-silc-plugin=${prefix}/lib/irssi \
+                        --without-silc-includes

Ideally this would be a varient and have a dependancy on irssi.

I then needed to bodge the files in /opt/local/lib/irssi/modules to make the module loading work

 sudo ln -s libsilc_core.dylib libsilc_core.so
 sudo ln -s libfe_common_silc.dylib libfe_common_slic.so

I'm sure all of this could be done better, but the functionality is very useful.

Hmm, so irssi won't load them unless they are named with .so? On the Mac either dylibs or so's can be dlopen()ed so obviously the symlink will work, but maybe we could update irssi to open either file type?

It certainly seems that it insists on .so. To test it you need to have a file called 'startup' in your .irssi dir containing

swelter:~/.irssi 504: cat startup                                                              9:39:08
LOAD silc

I can get it to install & irssi successfully loads with '/load silc' but if I try '/silc list-ciphers' it crashes:

Not sure where to go with it from here. Note it crashes with both irssi (irssi @0.8.12_1+perl) and irssi-devel (irssi-devel @5034_0).

Attaching my update to the silc-client port (also updates it to current version) in case someone has other ideas.
