An empty module_path to start with isn't ideal, but if all modules are
contained within a kernel directory (which is what we just tested) then it
isn't strictly an error. Don't assume that module_path has a value already.
When we fail to load the kernel, printing the result (which is guaranteed to
be nil) is not intended; print the name of the kernel.
autoboot_delay=NO is documented to wait for input and *not* autoboot, which
is the exact opposite of the current behavior.
Additionally, autoboot_delay=-1 is documented to disallow the user from
interrupting the boot (i.e. autoboot immediately), which was not previously
honored.
This also fixes the case insensitive comparison to be truly case
insensitive. This is kind of nit-picky, but the previous version would only
accept "no" and "NO".
Don't move this into config.reload because we may want to force reloads if
/boot changes out from under us later.
As a caution: changing kernels in lualoader at the moment might not be
loading all of your modules (in my testing, at least) from loader.conf(5).
This is a known problem.
Decimals screw up the escape sequence and the cursor will not get set. Right
now this only affects setting the cursor for drawing "Welcome to FreeBSD" --
the resulting number after our (x+(w/2)-9) calculation gets output as
"14.0."
This should be fixed at the interpreter level, rather than here, but this is
not a widespread problem at the moment so we'll fix it up in further work.

This is a pre-cursor to boot environment support in lualoader. Create a new
menu item type, "carousel_entry", that generally provides a callback to get
the list of items, a carousel_id for storing the current value, and the
standard name/func functions that an entry has.
The difference between this and a normal menu item, functionally, is that
selecting a carousel item will automatically rotate through available items
and wrap back at the beginning when the list is exhausted.
The 'name' function takes the choice index, current choice, and the list of
choices as parameters so that the menu item can decorate the name freely as
desired.
The 'func' function takes the current choice as a parameter, so it can act
accordingly.
The kernel menu item has been rewritten to use the carousel_entry type as
both an example and initial test of its functionality before it is used for
boot environment options.
Noting that we're in lualoader is nice, but it's not a difference we raelly
need to expose to Fred. Re-word it to match the 4th wording and reduce
differences.
This removes a redundant alias that has since been converted into a global
alias. It was converted to a global alias before to ensure that we always
have a way to go up one level in the menu.
Set it based on hint.acpi.0.rsdp. Initially, hint.acpi.0.disabled will be
respected. "Using System Defaults" will override whether it's explicitly
disabled by hint and re-load it based on whether it's present on the system.
Unlike the 4th version, this is not restricted to x86. I have no strong
reasoning for this, so this is definitely open to change.
This submenu is likely going to go away in favor of kernel selection as it
is done in forth at the moment, but for the time being don't descend into it
if we have no kernels available for listing.
