boot: Move boot source code /usr/src/stand.

sys/boot becomes stand/boot and lib/libstand becomes stand/lib.

My main reason is to have boot out of the way when for example grepping
in sys/. It also makes more sense since it's not really userland or
kernel code.

Other BSDs have moved their boot/standalone code around too, but maybe
with different directory layouts.

kernel: Remove ndis(4) and associated tools and stuff.

ndis(4) was a wrapper to allow running binary Windows network
drivers that conformed to the Network Driver Interface Specification,
i.e. NDIS.

It only ever supported drivers from the days of Windows XP and
Windows Server 2003 (i.e. NDIS 5.1). And even if one was actually
able to extract the .sys and .inf files from the driver package and
successfully convert them to a building module, which both were
adventures in itself, it could be any result when trying to run it,
depending on the card and driver, from resonably working to not
working, even crashing. But it did work for some cards, so it had
some limited merit in its time.

NetBSD removed it in 2018, FreeBSD in January 2021, so let's follow
suit now.

This commit puts the kernel build part under the same variable as well
so that the legacy kernel modules are not overwriten by the new ones.

Major kernel build infrastructure changes, part 1/2 (sys).

These changes are primarily designed to create a 2-layer machine and cpu
build hierarchy in order to support virtual kernel builds in the near term
and future porting efforts in the long term.

* Split arch/ into a set of platform architectures under machine/ and a
set of cpu architectures under cpu/. All platform and cpu header files
will be accessible via <machine/*.h>. Platform header files may override
cpu header files (the platform header file then typically #include's the
cpu header file).

* Any cpu header files that are not overridden will be copied directly
into /usr/include/machine/, allowing the platform to omit those header
files (not have to create degenerate forwarding header files).

* All source files access platform and cpu architecture files via the
<machine/*.h> path. The <cpu/*.h> path should only be used by
platform header files when including the lower level cpu header files.

* Require both the 'machine' and the 'machine_arch' directives in the
kernel config file.

* When building modules in the presence of a kernel config, use the IF
files, use*.h files, and opt*.h files provided by the kernel config
and do not generate them in each module's object directory. This
streamlines the module build considerably.

Reorganize the way machine architectures are handled. Consolidate the
kernel configurations into a single generic directory. Move machine-specific
Makefile's and loader scripts into the appropriate architecture directory.

Kernel and module builds also generally add sys/arch to the include path so
source files that include architecture-specific headers do not have to
be adjusted.

sys/<ARCH> -> sys/arch/<ARCH>
sys/conf/*.<ARCH> -> sys/arch/<ARCH>/conf/*.<ARCH>
sys/<ARCH>/conf/<KERNEL> -> sys/config/<KERNEL>

Make modules work again part 2 (final): Link the module build back into the
kernel build. It should now be possible to build and install the modules
using the 'mobj', 'modules' and 'minstall' targets in /usr/src/sys/Makefile,
though the preferred way is to simply build a kernel using the config or
the buildkernel and installkernel mechanisms.

This commit also fixes a few minor #include path problems that came up during
testing.

Tested with: config/make/install, direct make/install, and with
buildkernel/installkernel.

The following modules are not yet being built by the new system (and were
built with the old system): vesa.ko, fpu.ko, gnufpu.ko, ibcs2_coff.ko,
usb.ko, ng_mppc.ko, libiconv.ko.

kernel tree reorganization stage 1: Major cvs repository work (not logged as
commits) plus a major reworking of the #include's to accomodate the
relocations.

* CVS repository files manually moved. Old directories left intact
and empty (temporary).

* Reorganize all filesystems into vfs/, most devices into dev/,
sub-divide devices by function.

* Begin to move device-specific architecture files to the device
subdirs rather then throwing them all into, e.g. i386/include

* Reorganize files related to system busses, placing the related code
in a new bus/ directory. Also move cam to bus/cam though this may
not have been the best idea in retrospect.

* Reorganize emulation code and place it in a new emulation/ directory.

* Remove the -I- compiler option in order to allow #include file
localization, rename all config generated X.h files to use_X.h to
clean up the conflicts.

* Remove /usr/src/include (or /usr/include) dependancies during the
kernel build, beyond what is normally needed to compile helper
programs.

* Make config create 'machine' softlinks for architecture specific
directories outside of the standard <arch>/include.

* Bump the config rev.
