Add support for the go runtime on openbsd/amd64. This is based on
the existing freebsd runtime.
Threads are implemented using OpenBSD's rthreads, which are currently
disabled by default, however can be enabled via the kern.rthreads
sysctl.
For now, cgo is disabled.

All but two packages depend on net:
debug/proc
os/signal
With this change, we can produce
a working build with GOOS=plan9.

Correct a few error messages (libcgo -> runtime/cgo)
and delete old nacl_386.c file too.
Fixes#1657.

In this specific package crosscall2 is already defined in a .S
file anyhow. This avoids a warning about mismatched
alignment.

A cursory reading of the cgo code suggests this
should be necessary, though I don't have access
to a FreeBSD machine for testing.

#pragma dynexport is no longer needed for
this use of cgo, since the gcc and gc code are
now linked together into the same binary.
It may still be necessary later.
On the Mac, you cannot use the GOT to resolve
symbols that exist in the current binary, so 6l and 8l
translate the GOT-loading mov instructions into lea
instructions.
On ELF systems, we could use the GOT for those
symbols, but for consistency 6l and 8l apply the
same translation.
The translation is sketchy in the extreme
(depending on the relocation being in a mov
instruction) but it verifies that the instruction
is a mov before rewriting it to lea.
Also makes typedefs global across files.
Fixes#1335.
Fixes#1345.
