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.

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.

retrofit Safe Mode loader menu item actions

The menu item is now made completely independent with the ACPI item - most
modern systems seem to require ACPI and become even more "unsafe"
without it.
Safe Mode no longer disables APIC for the same reason.
kbdmux is not disabled as this feature has proven itself stable.

New actions:
- SMP is disabled in the Safe Mode now
- eventtimers are forced to periodic mode (some real and virtual systems
seem to have problems otherwise)
- geom extra vigorous integrity checking is disabled, this is to
facilitate migration from previous versions

Possible short term to do:
- make SMP switch a separate menu item
- restore APIC switch as a separate menu item

Longer term to do:
- turn various tweaks into separate menu items in a Safe Mode sub-menu

Please consider adding a safety tweak to Safe Mode when introducing
new major features or changes that may cause instabilities.
