* tweak mksyscall*.pl to be more gofmt-compatible.
* add mkall.sh -syscalls option.
* add sys/mman.h constants on OS X

Permit system calls to be designated as non-blocking, meaning
that we simply call them without involving the scheduler.
This change by itself is mostly performance neutral. In
combination with a following change to the net package there
is a performance advantage.

Besides being more correct, it protects against people accidentally
exchanging the permission and open mode arguments to Open.

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.

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

parsing and printing to new syntax.
Use -oldparser to parse the old syntax,
use -oldprinter to print the old syntax.
2) Change default gofmt formatting settings
to use tabs for indentation only and to use
spaces for alignment. This will make the code
alignment insensitive to an editor's tabwidth.
Use -spaces=false to use tabs for alignment.
3) Manually changed src/exp/parser/parser_test.go
so that it doesn't try to parse the parser's
source files using the old syntax (they have
new syntax now).
4) gofmt -w src misc test/bench
4th set of files.

* rename PORT.sh -> mkall.sh (hopefully more obvious),
change behavior: run commands by default.
* pull more constants out of #defines automatically,
instead of editing large lists by hand.
* add Recvfrom, Sendto
add os.O_EXCL.

* use 64-bit file system calls (Linux, Darwin)
* use 32-bit [sic] uid/gid calls (Linux)
* fix sockets on Linux
Darwin/386 works again.
Linux/386 is better but must never have worked;
there are still bugs surrounding the creation of new
threads in the runtime package.
