runtime: openbsd amd64 runtime support 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.

runtime: change amd64 startup convention Now the default startup is that the program begins at _rt0_amd64_$GOOS, which sets DI = argc, SI = argv and jumps to _rt0_amd64. This makes the _rt0_amd64 entry match the expected semantics for the standard C "main" function, which we can now provide for use when linking against a standard C library.
