The mmap system call varies across BSDs. Move mmap and munmap into
the operating system dependent files. This will be needed to add
syscall support for OpenBSD.

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.

The change adds specialized type algorithms
for slices and types of size 8/16/32/64/128.
It significantly accelerates chan and map operations
for most builtin types as well as user structs.

Some tests are significantly faster (50%), a few are slower (up to 30%).
Fannkuch is confusing: parallel code is a little slower for gc, non-parallel and all gccgo runs are faster.
