Konstantin Belousov 5dc7e31a09 Control implicit PROT_MAX() using procctl(2) and the FreeBSD note 
feature bit.

In particular, allocate the bit to opt-out the image from implicit
PROTMAX enablement.  Provide procctl(2) verbs to set and query
implicit PROTMAX handling.  The knobs mimic the same per-image flag
and per-process controls for ASLR.
