This commit refactors the UMA small alloc code and
removes most UMA machine-dependent code.
The existing machine-dependent uma_small_alloc code is almost identical
across all architectures, except for powerpc where using the direct
map addresses involved extra steps in some cases.
The MI/MD split was replaced by a default uma_small_alloc
implementation that can be overridden by architecture-specific code by
defining the UMA_MD_SMALL_ALLOC symbol. Furthermore, UMA_USE_DMAP was
introduced to replace most UMA_MD_SMALL_ALLOC uses.

We previously defaulted to using sc(4) with a special case to prefer
vt(4) when booted via UEFI. As vt(4) is now always the default we can
simplify this.

There are two improvements to the TCP blackhole support:
(1) If net.inet.tcp.blackhole is set to 2, also sent no RST whenever
a segment is received on an existing closed socket or if there is
a port mismatch when using UDP encapsulation.
(2) If net.inet.tcp.blackhole is set to 3, no RST segment is sent in
response to incoming segments on closed sockets or in response to
unexpected segments on listening sockets.
Thanks to gallatin@ for suggesting such an improvement.

Previously, it was necessary to set WITHOUT_INET_SUPPORT when building
the kernel without INET, and WITHOUT_INET6_SUPPORT when building the
kernel without INET6, or else the modules build would fail. The
LINT-NOINET and LINT-NOINET6 configs did this using makeoptions.
After recent changes, this is no longer required, so remove these
makeoptions. This avoids masking potential future build issues when
these aren't set.

syscons is not compatible with UEFI boot. This is noted in syscons(4),
but not mentioned in vt(4) where the kern.vty tunable (used to select vt
or sc) is documented. Add a note so that if someone reads vt(4) but not
sc(4) they are not surprised by having no usable console.

In vm_pageout_scan_inactive, release the object lock when we go to
refill the scan batch queue so that someone else has a chance to acquire
it. This improves access latency to the object when the pagedaemon is
processing many consecutive pages from a single object, and also in any
case avoids a hiccup during refill for the last touched object.

When biofinish calls g_io_deliver with an error of ENOMEM, that kicks
off the slowdown protocol, forcing I/O to go through g_down rather than
be directly dispatch. One of the side effects is that the I/O is
resubmitted, so the start routines get called recursively, leading to a
recursive lock panic. Rather than make the periph lock recursive, drop
and reacquire the lock around such calls to biofinish.
For nda, this happens only when we can't allocate space to construct a
TRIM. For ada and da, this is only for certain ZONE operations.

Update to eliminate bogus min to ensure 0 was never passed to
pause. Instead, requrest 1ms with an 'infinite' precision, which
defaults to whatever the underlying time counter can do. This should
ensure we run fairly quickly to start processing done events, while
still giving a small pause for the system to catch its breath. This rate
limiter still is less than ideal, and this commit doesn't change
that. It should really have no functional change: it just uses a better
interface to express the desired sleep.

Rather than using a package per driver add fine(r) grained flavors

arp(8) usually disallows adding a static ARP entry for an IP address
which is not configured on a local interface.
Change this to allow such ARP entries to be added if '-i' is provided to
specify the interface the ARP entry relates to.
Due to limitations in the kernel lltable, this still requires that a
host route exists for the target address, but allows static ARP entries
to be configured to proxy ARP for, e.g., local jails which use an IPv4
address with a /32 route.
