[GRASS5] G_socks_* unix socket wrapper functions...

I agree with Eric.  It looks like you have IPC on Mac OS X.  Do you want to go
out on the high wire and test it? A net is optional.

Actually, you can test IPC with some test programs from the Linux Documentation
Project or from the Cygwin Utils work.  These are fairly portable.  I used both
while debugging the Cygwin IPC code so I can probably help you with that.  These
test programs require that you have some knowledge of IPC message queues to
verify the results.

Another way to test is to compile the IPC version of grass and see if the XDRIVER
works for you.  This method doesn't require any knowledge of IPC messaging.

To test it you can do a 'make distclean', then remake everything - use
'./configure --with-ipc' to enable the IPC code, or just run "./README.ipc new"
which should set up and recompile the necessary routines.

On some systems IPC has resulted in faster graphics so there may be added bonus
for you.
