MFC r257650:

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.

Update legacy static assignments in old code to support dynamic framing,
plotting, and alignment coinciding with enhancements in SVN r242667.

Since the introduction of SVN r244048 and [follow-up] r244089, it is now
safe to build upon ``boot_serial?'' functionality to make safer UI choices.

+ This patch does not change user experience or functionality
+ 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)

Add ontop of my existing boot loader Forth code, including support for
submenus. See menusets.4th(8) for additional details including examples.

Discussed on arch and recommended for inclusion at the devsummit.

This change does not alter the appearance or user experience, only enhances
possibilities.

Since the introduction of the new advanced boot menu (r222417), options like
"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.

Unset the environment variables associated with individual menu items
before invoking the kernel.

Quoting submitter:

The issue is with the new boot loader menu. It adds many loader variables
including ones that contain ANSI color escapes.

Obviously, these ANSI codes don't play well with serial consoles when
kenv(1) is executed without arguments (reports vary as to what happens,
but it's never pretty).

The net-effect is that kenv(1) no longer reports menu-related variables.

In essence, kenv(1) output should now appear the same as on RELENG_8
(which lacks the new boot loader and didn't use any such variables).
Thus, restoring serial console glory.

Restore behavior of the autoboot_delay="-1" boot menu setting to the
