[PATCH v3 13/20] bsd-user: Implement sysctl kern.proc, except kern.proc.full_path

[Warner Losh <imp@bsdimp.com>]

From: Stacey Son <sson@FreeBSD.org>

Use the recently committed conversion routines to implement all the
kern.proc flavors, except for the full path (the prereqs of which aren't
yet in qemu-project's master branch).
