When checking to see if a video output's _ADR matches an entry in the
parent adapter's _DOD list, only check the low 16 bits of both _ADR and
_DOD. The language in the ACPI spec seems to indicate that the _ADR values
should exactly match the entries in _DOD. However, I assume that the
masking added to _DOD values was added to work around some known busted
machines (the commit history doesn't indicate either way), and the ACPI
spec does require that the low 16 bits are unique for all video outputs,
so only check the low 16 bits should be fine.
This fixes recognition of video outputs that use the new standardized
device ID scheme in ACPI 3.0 that set bit 31 such as certain Dell laptops.

This is an import of code, mostly from Giuseppe Lettieri,
that revises the netmap memory allocator so that the
various parameters (number and size of buffers, rings, descriptors)
can be modified at runtime through sysctl variables.
The changes become effective when no netmap clients are active.
The API is mostly unchanged, although the NIOCUNREGIF ioctl now
does not bring the interface back to normal mode: and you
need to close the file descriptor for that.
This change was necessary to track who is using the mapped region,
and since it is a simplification of the API there was no
incentive in trying to preserve NIOCUNREGIF.
We will remove the ioctl from the kernel next time we need
a real API change (and version bump).
Among other things, buffer allocation when opening devices is
now much faster: it used to take O(N^2) time, now it is linear.

improve upon the system by giving the user a "Help" button instead of requiring
the user to press F1.
NOTE: In FreeBSD-9 and higher, dialog(1) does not support the F1 hook, so the
mechanism for providing help to the user had to be changed to a button.
This now means we can resurrect *.hlp files from usr.sbin/sysinstall/help/ as-
is and reusing them as-needed in bsdconfig (holding to the goal of losing as
little functionality from sysinstall as possible).

It turns out that as documented, PCF8563_R_SECOND_VL (i.e. battery low)

to be set, i.e. pcf8563_settime(), and not just PCF8563_R_SECOND in order
for PCF8563_R_SECOND_VL to stick. Thus, we just issue a warning during
