Rather than overloading the meanings of the Mach statuses, introduce a
new set for use internally in the fault code. This makes the control
flow easier to follow and provides some extra error checking when a
fault status variable is used in a switch statement.
vm_fault_lookup() and vm_fault_relookup() continue to use Mach statuses
for now, as there isn't much benefit to converting them and they
effectively pass through a status from vm_map_lookup().

ACPI implementation of device_get_property would return "-1" when
property was found, but it's type wasn't supported.
This causes device_has_property to return false in that scenario, which
arguably could be considered as incorrect.
Fix that by returning "0" in that case.

This allows it to work with unmapped mbufs. In particular,
in_cksum_skip() calls no longer need to be preceded by calls to
mb_unmapped_to_ext() to avoid a page fault.

in_cksum() and related routines are implemented separately for each
platform, but only i386 and arm have optimized versions. Other
platforms' copies of in_cksum.c are identical except for style
differences and support for big-endian CPUs.
Deduplicate the implementations for the rest of the platforms. This
will make it easier to implement in_cksum() for unmapped mbufs. On arm
and i386, define HAVE_MD_IN_CKSUM to mean that the MI implementation is
not to be compiled.
No functional change intended.

The alq interfaces are 100% in-kernel, so make this whole file #ifdef
_KERNEL. There's no users of this in the tree outside of the kernel, nor
does it define anything that could be useful at peeking into the state

There's no harm in including sys/types.h here and acct.h needs it. This
file isn't defined by any standard, so what we do here wrt namespaces
likely doesn't matter. If it does, it will be easy enough to add the
necessary __BSD_VISIBLE guards in the future.

Variables must be quoted if they contain non-alphanumeric characters.
Warner noted in the review that the lack of quoting causing problems
here is rather an edge case. I believe that it's worth adding the quotes
here anyway because this is what the specification says and there is no
good reason not to follow it.

bsddialog is an attempt to write in permissive license a replacement for
libdialog.
While it is still in early stage it is good enough to already be used in
many areas, it is imported as private lib until it matures enough to be
considered as having a stable ABI
It breaks intree partial builds for every library depending on ncurses
because ncursesw.a (built without PIC) will be the first the library
path for the linker to resolve -lncursesw
Although not part of the standard, this file is sometimes included with
-D_POSIX_C_SOURCE=<value> or -D_XOPEN_SOURCE=<value>. Limit those
sturctures that use types hidden by __BSD_VISIBLE to when they are
visible.
