Fix EUC ESDB and JIS CS-mapper.  This also fixes an identity transformation
by "cat foo.euc-jp | iconv -f euc-jp -t utf-8 | iconv -f utf-8 -t euc-jp".
Rework the aicasm build machinery so that it gets built along with toolchain
components instead of with the kernel and/or modules.  This ensures that it
gets built with the host compiler, not the compiler in obj/... used to build
the target components (which may be a cross-compiler outputting code for a
different architecture and using header files with types and options set up
for the wrong architecture).

Remove the duplicated implementations of some bus_space functions and use
the essentially identical generic implementations instead.  The generic
implementations differ only in the spelling of a couple variable names
and some formatting differences.
When building the textproc/docproj port, the ports-mgmt/pkg port

Quiesce warning around gcc_assert() for an inline macro that uses
a static variable.  This code has been moved around in gcc, but is still in
use in the latest trunk version of the compiler.

This explanation is supposed to be simpler and better.  In particular
"comparing it to the snprintf API provides lots of value, since it raises the
bar on understanding, so that programmers/auditors will a better job calling
all 3 of these functions."

Begin reducing code duplication in arm pmap.c and pmap-v6.c by factoring
out common code related to mapping device memory into a new devmap.c file.

Remove the growing duplication of code that used pmap_devmap_find_pa() and
then did some math with the returned results to generate a virtual address,
and likewise in reverse to get a physical address.  Now there are a pair
of functions, arm_devmap_vtop() and arm_devmap_ptov(), to do that.  The
bus_space_map() implementations are rewritten in terms of these.
This files should have been included in r257648.
Defer loading of kernel and modules if the beastie menu is enabled. Add a
kernel selection menu to the beastie menu. List of kernels is taken from
`kernels' in loader.conf(5) as a space (or comma) separated list of names
to display (up to 9). If not set, default value is "kernel kernel.old".
Does not validate that kernels exist because the next enhancement will be
to allow selection of the root device.

For C++ programs, don't emit any explicit dependency to libstdc++.a or
libc++.a during the early build stages (bootstrap-tools, build-tools,
cross-tools), since it is not possible to know in advance which C++
library is available on the host system.

Instead, just use the bootstrap compiler's built-in default.  This
should eventually make it possible to build stable/9 on head, or on
stable/10, which ship without libstdc++ by default.

Move remaining code and data related to static device mapping into the
new devmap.[ch] files.  Emphasize the MD nature of these things by using
the prefix arm_devmap_ on the function and type names (already a few of
these things found their way into MI code, hopefully it will be harder to
do by accident in the future).
Remove the 'vdev' abstraction that was meant to sit on top of device models
in the kernel. This abstraction was redundant because the only device emulated
inside vmm.ko is the local apic and it is always at a fixed guest physical
address.
