- Add "fdt addr" subcommand that lets you specify preloaded blob address
- Do not pre-initialize blob for "fdt addr"
- Do not try to load dtb every time fdt subcommand is issued,
do it only once
- Change the way DTB is passed to kernel. With introduction of "fdt addr"
actual blob address can be not virtual but physical or reside in
area higher then 64Mb. ubldr should create copy of it in kernel area
and pass pointer to this newly allocated buffer which is guaranteed to work
in kernel after switching on MMU.
- Convert memreserv FDT info to "memreserv" property of root node
FDT uses /memreserve/ data to notify OS about reserved memory areas.
Technically it's not real property, it's just data blob, sequence
of <start, size> pairs where both start and size are 64-bit integers.
It doesn't fit nicely with OF API we use in kernel, so in order to unify
thing ubldr converts this data to "memreserve" property using the same
format for addresses and sizes as /memory node.
Make the following interface changes to my beastie boot menu:
+ Move boot options to a submenu
+ Add a new "Boot Single" menu item
+ Make "Boot" item and new "Boot Single" item reverse when boot_single is set
+ Add new "Load Defaults" item (in new "Boot Options" submenu) for overridding
loader.conf(5) provided values with system defaults.

Rasperry Pi firmware has a set of hardcoded pathes it uses to fill
FDT with system-specific information like display resolution, memory
size, UART and SDHCI clocks, ethernet MAC address. Handle two of them:
- Add placeholder for ethernet MAC address
- Move display node out of "axi" node
+ Cleanup syntax, slim-down code, and make things more readable
+ Introduce new +c! operator and ilk to reduce heap usage/allocations
+ Add safemode_enabled? safemode_enable and safemode_disable functions
+ Add singleuser_enabled? singleuser_enable singleuser_disable functions
+ Add verbose_enabled? verbose_enable and verbose_disable functions
+ Centralize strings (also to reduce heap usage)

The sole purpose of this change is to make sure that sizeof produces
"canonical" sizes for these structures. This is to avoid triggering
bugs in the BIOSes that properly handle only the canonical values of
input length provided to INT 13h AH=48h.
The canonical sizes are: 30 for v2, 66 for v3, etc.
Buggy BIOS code probably looks like:
if (input_length > 30) { /* > v2 */
assume that input length is 66 /* assume v3 or later */
}
This should fix boot problems at least on Supermicro X8DT6 and possibly
on P410i Smart Array Controller (as found in e.g. HP DL360 G7).

- Make sys/boot/pc98/boot2 always build with gcc for now, until we can
figure out a way to shrink it enough when building with clang.
- Since sys/boot/p98/cdboot uses .code16 directives, which are not yet
supported by clang's integrated assembler, use -no-integrated-as,

GIANT from VFS. This code is particulary broken and fragile and other
in-kernel implementations around, found in other operating systems,
don't really seem clean and solid enough to be imported at all.
If someone wants to reconsider in-kernel NTFS implementation for
inclusion again, a fair effort for completely fixing and cleaning it
up is expected.
In the while NTFS regular users can use FUSE interface and ntfs-3g
port to work with their NTFS partitions.
This is not targeted for MFC.
"boot verbose", "single user mode", "ACPI" and more are now stateful boolean
menuitems rather than direct action-items.
A short-coming in this new menu system is that when a user sets a non-default
value in loader.conf(5), this non-default state is not reflected in the menu
-- leading to confusion as to whether the option was taking effect or not.
This patch adds dynamic menuitem constructors _and_ the necessary Forth
callbacks to initialize these stateful menuitems -- causing the aforementioned
menuitems to adhere to loader.conf(5) settings.

executed to better differentiate between loader-specific errors and kernel-
specific errors (if ever any of either).
This type of functionality hasn't been required before the introduction of the
advanced menu system (r222417). Adding this functionality will help different-
iate errors at the loader-level such as a BTX halt caused by heap exhaustion
and errors that may be involved with executing the kernel (wrong architecture
for example). A user can learn that messages before "Booting..." are related to
the loader(8) environment and it's Forth-ilk, while those after are not
related to loader(8) -- the point that loader(8) has ``left the building''.
This patch also includes a man-page update to color.4th(8) as the color logic
moves to a lower-level (from being included by beastie.4th to being included
by loader.4th).
After noticing a delay between execution of the overloaded "boot" FICL word and
the display of text on-screen, gcooper confirmed that the introduction of a
builtin memory test (disabled by adding hw.memtest.tests="0" to loader.conf(5))
was the cause of the delay.
This patch adds an echo to produce "Booting..." when the overloaded "boot" word
is executed (this includes from the interactive command-prompt on all arches,
from the menu system on arches that run the beastie menu, and even those arches
that run the menu but disable it by setting beastie_disable="YES" in
loader.conf(5)). When loader_color="YES" in loader.conf(5), the same message is
produced but in white text on a blue background (only the letters produced have
this background -- opposed to perhaps the entire line).
