vm_phys: improve robustness of fictitious ranges

With the current implementation of managed fictitious ranges when
also using VM_PHYSSEG_DENSE, a user could try to register a
fictitious range that starts inside of vm_page_array, but then
overrruns it (because the end of the fictitious range is greater than
vm_page_array_size + first_page). This would result in PHYS_TO_VM_PAGE
returning unallocated pages from past the end of vm_page_array. The
same could happen if a user tried to register a segment that starts
outside of vm_page_array but ends inside of it.

In order to fix this, allow vm_phys_fictitious_{reg/unreg}_range to
use a set of pages from vm_page_array, and allocate the rest.

Revert the logic change from r269540.  If the opt_inet6.h file is empty
we set MK_INET6_SUPPORT to no, not if we do define INET6.
This way we do not try to build IPv6 parts in if the kernel doesn't support
them.

This unbreaks several kernel configurations building modules but no INET6.
don't OR integer error values together as this does not make sense.
Instead bail on the first failed command.
Provide -o vers= support for mount_nfs.

Our mount_nfs does use -o nfsv<2|3|4> or -2 or -3 to specify the version.
OSX (these days), Solaris, and Linux use -o vers=<2,3,4>.

With the upcoming autofs support we can make a lot of (entrerprisy) setups
getting mount options from LDAP just work by providing -o vers= compatibility.
