This setup will add the trusted certificates from the Mozilla NSS bundle
to base.
This commit includes:
- CAROOT option to opt out of installation of certs
- mtree amendments for final destinations
- infrastructure to fetch/update certs, along with instructions
A follow-up commit will add a certctl(8) utility to give the user control
over trust specifics. Another follow-up commit will actually commit the
initial result of updatecerts.
This work was done primarily by allanjude@, with minor contributions by
myself.

picobsd/tinyware has had this compact HTTPD server for a long time, and some
people do use it. Move it out into usr.sbin well in advance of any action
being taken on picobsd.
This has been gated behind an HTTPD option defaulted to *off*, primarily for
two reasons:
1.) This code likely needs a good audit, as it's been living off in picobsd
land for a long time, and
2.) We don't currently ship an httpd and this may not be a welcome surprise.

Parts of the fusefs tests trigger a bug in current versions of llvm: IR
representation of some routine for the MIPS targets is a function with a
large number of arguments. This then leads the compiler on an hour+ long
goose chase, which is OK if you build the current tree but less-so if you're
trying external toolchain or doing a universe build involving mips when it
eventually gets switched over to LLVM.
Better, accurate details can be found in LLVM PR43263.

to the traditional tree(3) RB trees, but using an array (preallocated,
linear chunk of memory) to store the tree.
This avoids allocation overhead, improves memory locality,
and makes it trivially easy to share/transfer/copy the entire tree
without the need for marshalling. The downside is that the size
is fixed at initialization time; there is no mechanism to resize
it.

There are several mechanisms by which a vm_page reference is held,
preventing the page from being freed back to the page allocator. In
particular, holding the page's object lock is sufficient to prevent the
page from being freed; holding the busy lock or a wiring is sufficent as
well. These references are protected by the page lock, which must
therefore be acquired for many per-page operations. This results in
false sharing since the page locks are external to the vm_page
structures themselves and each lock protects multiple structures.
Transition to using an atomically updated per-page reference counter.
The object's reference is counted using a flag bit in the counter. A
second flag bit is used to atomically block new references via
pmap_extract_and_hold() while removing managed mappings of a page.
Thus, the reference count of a page is guaranteed not to increase if the
page is unbusied, unmapped, and the object's write lock is held. As
a consequence of this, the page lock no longer protects a page's
identity; operations which move pages between objects are now
synchronized solely by the objects' locks.
The vm_page_wire() and vm_page_unwire() KPIs are changed. The former
requires that either the object lock or the busy lock is held. The
latter no longer has a return value and may free the page if it releases
the last reference to that page. vm_page_unwire_noq() behaves the same
as before; the caller is responsible for checking its return value and
freeing or enqueuing the page as appropriate. vm_page_wire_mapped() is
introduced for use in pmap_extract_and_hold(). It fails if the page is
concurrently being unmapped, typically triggering a fallback to the
fault handler. vm_page_wire() no longer requires the page lock and
vm_page_unwire() now internally acquires the page lock when releasing
the last wiring of a page (since the page lock still protects a page's
queue state). In particular, synchronization details are no longer
leaked into the caller.
The change excises the page lock from several frequently executed code
paths. In particular, vm_object_terminate() no longer bounces between
page locks as it releases an object's pages, and direct I/O and
sendfile(SF_NOCACHE) completions no longer require the page lock. In
these latter cases we now get linear scalability in the common scenario
where different threads are operating on different files.
__FreeBSD_version is bumped. The DRM ports have been updated to
accomodate the KPI changes.

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

The page daemon periodically invokes uma_reclaim() to reclaim cached
items from each zone when the system is under memory pressure. This
is important since the size of these caches is unbounded by default.
However it also results in bursts of high latency when allocating from
heavily used zones as threads miss in the per-CPU caches and must
access the keg in order to allocate new items.
With r340405 we maintain an estimate of each zone's usage of its
(per-NUMA domain) cache of full buckets. Start making use of this
estimate to avoid reclaiming the entire cache when under memory
pressure. In particular, introduce TRIM, DRAIN and DRAIN_CPU
verbs for uma_reclaim() and uma_zone_reclaim(). When trimming, only
items in excess of the estimate are reclaimed. Draining a zone
reclaims all of the cached full buckets (the previous behaviour of
uma_reclaim()), and may further drain the per-CPU caches in extreme
cases.
Now, when under memory pressure, the page daemon will trim zones
rather than draining them. As a result, heavily used zones do not incur
bursts of bucket cache misses following reclamation, but large, unused
caches will be reclaimed as before.
