r31386 changed how the size of the VM page array was calculated to be
less wasteful. For most systems, the amount of memory is divided by
the overhead required by each page (a page of data plus a struct vm_page)
to determine the maximum number of available pages. However, if the
remainder for the first non-available page was at least a page of data
(so that the only memory missing was a struct vm_page), this last page
was left in phys_avail[] but was not allocated an entry in the VM page
array. Handle this case by explicitly excluding the page from
phys_avail[].

subtree is already zero, then setting the "largest contiguous free block"
hint for that subtree to anything other than zero makes no sense. To be
clear, assigning a value to the hint that is too large is not a correctness
problem, only a pessimization.
Dragonfly BSD has applied the same change to blst_meta_alloc() but not
blst_meta_fill().

Currently the PCI domain is initialized with the instance GUID in
vmbus_pcib_attach(). It turns out the GUID can change across VM reboot,
while some users want a persistent value for PCI domain. The solution is
that we can change to use the device serial number, which starts with 1
and is unique within a VM.

This happens when closing a socket with upcall, and trace is: soclose()->
... protocol ... -> soisdisconnected() -> socantrcvmore_locked() ->
sowakeup() -> soisconnected().
Right now this case is innocent for two reasons. First, soisconnected()
doesn't clear SS_ISDISCONNECTED flag. Second, the mutex to lock the
socket is the socket receive buffer mutex, and sodisconnected() first
disables the receive buffer. But in future code, the mutex to lock
socket is different to buffer mutex, and we would get undesired mutex
recursion.
The fix is to check SS_ISDISCONNECTED flag before calling upcall.
Before this test just checked scenario of setting and removing the accept
filter at different states of the socket. Now it also checks that accept
filter works: we connect to the server, and then check that we can't accept,
then we send 1 byte of data and check again.
The cmd argument passed to extattrctl() is not decoded as a string constant
but is just printed in hex. The value is filesystem-specific but in
practice is only used with UFS1 filesystems.

All manpages in base are now compatible with mandoc(1), all roff documentation
will be relocated in the doc tree. man(1) can now use groff from the ports tree
if it needs.
Also remove checknr(1) and colcrt(1) which are only useful with groff.

The futimens() and utimensat() compat stubs allowed using these functions on
kernels that did not have the system calls yet (10.2, old 11-current).
Also remove the documentation of the [ENOTSUP] error that could occur with
an old kernel.
A -DNO_CLEAN build may fail because the depend files refer to the deleted
files.

This is being done to make the documentation for atf-check(1) easier to find/more
intuitive for new users, because atf_check is the atf-run(1) shell version of the
standalone atf-check(1) command, which is used in atf-sh(3) test programs.

arm, mips, and powerpc all implement pmap_mapdev_attr() and pmap_unmapdev(),
so add those archs to the checks. powerpc also includes the atomic_swap_*()
functions, so add that to the supported list as well. Not tested except by
compiling powerpc.

Starting the fc -e editor can execute arbitrary script, and executing
arbitrary script with INTOFF in effect may cause unexpected results.
This change (together with other changes) serves mainly to allow asserting
that INTOFF is not in effect when starting the evaluation of a node.
