autoconf check for socklen_t

Here's a configure check to see if socklen_t is defined.  Even though my
man pages on linux say accept(2) takes (int *) as it's 3rd arg, the
sys/socket.h files begs to differ.

If not defined (which is doesn't seem to be on AIX 4.2.1), it can be
explicitly typedef'ed to (unsigned int).  Now do mainstream code changes
get submitted back to the openbsd group, or would it be better to submit to
this list?

After defining all those variables to socklen_t, this should clean up the
spurious errors spewed forth from AIX's native compiler, about the uncast
connect, accept and bind calls.
