Add a simple libproc for use by libdtrace. This is based on
ptrace, kevent and kvm instead of procfs like the one in Solaris.
Does it actually depend on kvm (/dev/kmem) or just on libkvm interfaces?
We've been trying to eliminate dependence on /dev/kmem for tools that
otherwise don't require privilege over the last few years, in the interests of
eliminating setgid kmem. Generally, we've done this by adding sysctls that
explicitly export the required information, and in some cases, those sysctls
have been wrapped by existing libkvm interfaces. I guess this is most easily
answered by knowing if things using libdtrace->libproc require setgid to
