THIS WILL BREAK THE BUILD.
The z files have socketpair code in them that was
written by hand; breaking the build with this is the first
step in getting rid of that hand-written code.

In this change I'd like to combine the common code that is
present in syscall_darwin.go and syscall_freebsd.go. I
have three reasons for wanting to do this now:
1. reducing code duplication is nearly always good :-)
2. the duplication will get worse if I duplicate this code
a third time for the NetBSD port I'm working on, which
I need to do almost immediately
3. by making this change all in one lump and ignoring any
commonality with the syscall_linux*.go files the diff
is long but, I think, readable
In future it may be possible to cherry pick functions that
also apply to Linux and put them in (say) syscall_unix.go,
and of course some functions may diverge in future and have
to move out to OS or architecture specific files, but today
I want just the low hanging fruit.
Tested and passed on:
Darwin (Snow Leopard, 10.6): amd64 and 386
FreeBSD (8.0-RELEASE): 386 only(*)
(*) All my virtualisation software has stopped playing nice
with FreeBSD for the moment, so I don't have facilities to
test the amd64 port. As the OS X port is OK and the diff
looks all right to my eyes I shall keep my fingers crossed.
If someone with a FreeBSD/amd64 system cares to test and
report I would be appreciative.
2010-03-27 update: I have replaced my virtualisation software, and have working FreeBSD/i386 and FreeBSD/amd64 virtual machines again.
As I hoped (and expected -- programmers are optimists :-) the code built and passed all but the two currently known to fail tests on FreeBSD/amd64. I rechecked FreeBSD/i386 too: same results.
