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.

- new heuristic: if both the opening { and closing } braces are on the
  same line, and the function body doesn't contain comments or is other-
  wise too long (e.g. signature too long), it is formatted as a one-line
  function

- related cleanups along the way

- gofmt -w src misc led to no additional changes as expected

No functional change, but when these files are regenerated
they change, leading to noisy diffs when working in the
syscall package.
