INHERIT_ZERO is an OpenBSD feature.
When a page is marked as such, it would be zeroed
upon fork().
This would be used in new arc4random(3) functions.

Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

Stop calling system calls "function calls".
Use "The .Fn system call" a-la "The .Nm utility".
When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.
referal from mmap to minherit for MAP_INHERIT. Fully document the
minherit.2 manual page (because frankly, my dear, however you think it
currently works is almost certainly wrong!). I may soon re-implement
MAP_COPY because I believe we can support it properly now, but I will have
to call it something else and that is for a later time.
mlock, mmap, mprotect, msync, munlock, and munmap are defined by
POSIX as taking void *. The const modifier has been added to
mlock, munlock, and mprotect as the standard dictates.
minherit comes from OpenBSD and has been updated to conform with
their recent change to void *.
madvise and mincore are not defined by POSIX, but their arguments
have been modified to be consistent with the POSIX-defined functions.
mincore takes a const pointer, but madvise does not due to the
MADV_FREE case.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
