swap_pager: avoid meta_transfer race
Function swp_pager_meta_transfer expects that after dropping and
reacquiring an object lock, the swap block it's processing still
exists, and has not been removed from the trie and freed. Rewrite to
avoid depending on that, by scrubbing, removing and freeing it before
releasing the lock.

man4: Add a comment about Hardware Notes
The Hardware Notes for each release are generated automatically from a

lib/libc/tests/string: improve memccpy "bounds" unit test
The purpose of the "bounds" test is to check that the function does not
overread the array bounds. The old unit test, copied from the strlcpy()
one, always ensured that we see the character c memccpy() is looking for
in the source array before the array ends. While this is correct for
strlcpy(), memccpy()'s specification does not guarantee that c is
present within the given size limit.
The updated test handles this case better, ensuring that the source
array ends early if c is not supposed to be present.

pf tests: Do not handle ipfw presence
Initially, it was added to cover a conflicting case of ipfw and pf used
together. But there are more drawbacks than benefits:
- A half of these tests are always skipped. That leads to
misunderstanding, while the test suite strives to avoid ambiguous
situations.
- Handling enabled ipfw on the test level is tedious, error-prone, and
less maintainable.
- CI and similar parties already know how to deal with ipfw for the test
suite, like making it open by default. Extra complexity is not needed.
In addition, ipfw+pf use cases are not officially supported.

kassert: Remove KASAN marking from DEBUG_POISON_POINTER
While this approach works for trapping reads of an uninitialized
pointer, it means that any attempt to store to the variable triggers a
KASAN report, which is not what we want. Simply remove the kasan_mark()
call. KMSAN will catch these kinds of bugs automatically anyway.

pctrie: create iterator
Define a pctrie iterator type. A pctrie iterator is a wrapper around a
pctrie that remembers a position in the trie where the last search
left off, and where a new search can resume. When the next search is
for an item very near in the trie to where the last search left off,
iter-based search is faster because instead of starting from the root,
the search usually only has to back up one or two steps up the
root-to-last-search path to find the branch that leads to the new
search target.
Every kind of lookup (plain, lookup_ge, lookup_le) that can begin with
the trie root can begin with an iterator instead. An iterator can also
do a relative search ("look for the item 4 greater than the last item
I found") because it remembers where that last search ended. It can
also search within limits ("look for the item bigger than this one,
but it has to be less than 100"), which can save time when the next
item beyond the limits and that is known before we actually know what
that item it is. An iterator can also be used to remove an item that
