Add new sysctls, KERN_PROC_ENV and KERN_PROC_AUXV, to return

environment strings and ELF auxiliary vectors from a process stack.

Make sysctl_kern_proc_args to read not cached arguments from the
process stack.

Export proc_getargv() and proc_getenvv() so they can be reused by
procfs and linprocfs.
