Revert "stddef.h: add unreachable() for C23 compliance"

Seems like a number of ports are *really* unhappy with this new
macro. These ports will have to be fixed and the patch reworked
to perhaps not affect C++ (see D54041). A general discussion on
how we expose new language features may also need to take place.

packages: Install development manpages in the -dev package

Add a new per-group SUBPACKAGE option to bsd.man.mk. When MANSPLITPKG
is enabled, this is forced to "-man", otherwise it defaults to empty
but can be overridden by the caller.

Use this in bsd.lib.mk to install library manpages in the -dev package
instead of the base package. This is nearly always preferable, since
library manpages are usually in section 2 or 3 and are only relevant
to people with development packages installed.

For manpages which should be installed in the base package even for
libraries, add a new MANNODEV group in bsd.lib.mk. Update existing
Makefiles to use this where appropriate.

share/man: Move many manpages to more correct packages

At the moment, all the manpages in share/man are in the utilities-man
package. Move some of them to the package they should actually be in,
using the new MANGROUPS feature.

Move all of section 3 to clibs-man. Although some of these are from
/usr/include/sys rather than libc, you can't practically use them
without libc, and clibs-man is where the libc manpages live already.

Move all of sections 4 and 9 to a new kernel-man package, except for
atf-test-case.4 which goes to tests-man. atf-test-case.4 is in the
wrong section, but this needs to be fixed upstream.

kernel-man requires special handling in generate-ucl.lua since it's
got a -man suffix but doesn't want the ' (manual pages)' automatic
suffix. For now, fix this by adding a list of packages that don't
get automatic suffixes.

rb_tree: augmentation shortcut

RB-tree augmentation maintains data in each node of the tree that
represents the product of some associative operator applied to all the
nodes of the subtree rooted at that node. If a node in the tree
changes, augmentation data for the node is updated for that node and
all nodes on the path from that node to the tree root. However,
sometimes, augmenting a node changes no data in that node,
particularly if the associated operation is something involving 'max'
or 'min'. If augmentation changes nothing in a node, then the work of
walking to the tree root from that point is pointless, because
augmentation will change nothing in those nodes either. This change
makes it possible to avoid that wasted work.

Define RB_AUGMENT_CHECK as a macro much like RB_AUGMENT, but which
returns a value 'true' when augmentation changes the augmentation data
of a node, and false otherwise. Change code that unconditionally walks
and augments to the top of tree to code that stops once an
augmentation has no effect. In the case of rebalancing the tree after
insertion or deletion, where previously a node rotated into the path
was inevitably augmented on the march to the tree root, now check to
see if it needs augmentation because the march to the tree root
stopped before reaching it.

Change the augmentation function in iommu_gas.c so that it returns
true/false to indicate whether the augmentation had any effect.
