- Move busdma_lock_mutex to subr_bus_dma.c.
- Move _busdma_lock_dflt to subr_bus_dma.c. This function was named a
couple of different things previously. It is not a public API but
an internal helper used in place of a NULL pointer. The prototype
is in <sys/bus_dma.h> as not all backends include
<sys/bus_dma_internal.h>.

Move mostly duplicated code in various MD bus_dma backends to support
bounce pages into sys/kern/subr_busdma_bounce.c. This file is
currently #include'd into the backends rather than compiled standalone
since it requires access to internal members of opaque bus_dma
structures such as bus_dmamap_t and bus_dma_tag_t.

It is one of the few remaining Giant-locked callouts. It would be
good to remove it, not mentioning that polling itself is not good.
If this cause keyboard/mouse freezes on some hardware, please set
loader tunable hw.atkbd.hz=1 as workaround and report the issue.

In my understanding this is only needed to workaround lost interrupts.
I was thinking to remove it completely, but the comment about edge-
triggered interrupt may be true and needs deeper investigation. ~1Hz
should be often enough to handle the supposedly rare loss cases, but
rare enough to not appear in top. Add sysctl hw.atkbd.hz to tune it.

We need to include bsd.endian.mk from bsd.compiler.mk to enable
compressed symbols only on FreeBSD little endian targets.
However, since we include bsd.compiler.mk from Makefile.inc1 and from
the build tools makefiles, it has to work on Linux and osx. Make the
error condition only when we're building natively (so that we are
forced to add a new architecture to the list).
Otherwise, define bogus, poisoned values and leave TARGET_ENDIANNESS
undefined. Since we don't actually use TARGET_ENDIANNESS for anything
in the cross building phase, these values are a failsafe agianst their
use. The one place in the build phase that detects endian is
appropriately protected.

Previously the driver duplicated code from cryptosoft.c to handle
certain edge case AES-CCM and AES-GCM requests. However, this
approach has a few downsides:
1) It only uses "plain" software and not accelerated software since it
uses enc_xform directly.
2) It performs the operation synchronously even though the caller
believes it is invoking an async driver. This was fine for the
original use case of requests with only AAD and no payload that
execute quickly, but is a bit more disingenuous for large requests
which fall back due to exceeding the size of a firmware work
request (e.g. due to large scatter/gather lists).
3) It has required several updates since ccr(4) was added to the tree.
Instead, allocate a software session for AES-CCM and AES-GCM sessions
and dispatch a cloned request asynchronusly to the software session.

This function clones an existing crypto request, but associates the
new request with a specified session. The intended use case is for
drivers to be able to fall back to software by cloning a request and
dispatch it to an internally allocated software session.

It turns out that we still need xlocal.h protection for when we're
cross building on Linux. Linux doesn't have this file, but os/x
does. Before, we'd assume we didn't have it, like old FreeBSD, when
cross compiling. After the latest update, all that code was removed so
cross compiling needs to be handled separaetly. Do so by defining
HAVE_XLOCALE_H only when we're not building on linux. This allows us
to build the mkmagic build tool needed to build file(1).

The original logic was to check if there's no filter and the address is
misaligned relative to the requirements. The refactoring in
c606ab59e7 missed this, and instead caused
it to return failure if the address *is* properly aligned.
Make neta use frequency obtained from clock, instead of
hardcoded one. Use default frequency in case of clock
device failure. Remove unnecessary function calls
to obtain frequency and use cached one instead.

The majority of this work was done in 2018 saved as git stashes within
a git-svn tree and migrated to the git tree. The regression occurred
when the various stashes were sequentially merged to create individual
