This CL fixes code that incorrectly assumes that int is 32 bits wide.
Specifically, the socketpair system call expects a pointer to a pair
of int32s, not a pair of ints. Fix this inside the wrappers without
changing the APIs.
Update #2188.

Since NUL usually terminates strings in underlying syscalls, allowing
it when converting string arguments is a security risk, especially
when dealing with filenames. For example, a program might reason that
filename like "/root/..\x00/" is a subdirectory or "/root/" and allow
access to it, while underlying syscall will treat "\x00" as an end of
that string and the actual filename will be "/root/..", which might
be unexpected. Returning EINVAL when string arguments have NUL in
them makes sure this attack vector is unusable.

This syscall was inadvertently exported when fixing
Getrlimit/Setrlimit on 32-bit platforms.

- syscall (not os) now defines the Errno type.
- the low-level assembly functions Syscall, Syscall6, and so on
return Errno, not uintptr
- syscall wrappers all return error, not uintptr.

* 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.

Regenerate zsyscall_linux_*.go files with recent changes to
mksyscall.sh.
Add socketpair to syscall_linux_amd64.go; for some reason it
was in the generated file but not in the source file.

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.

For 386 we use the [f]statfs64 system call, which takes three
parameters: the filename, the size of the statfs64 structure,
and a pointer to the structure itself.

- applied gofmt -w $GOROOT/src

* 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.
