loader: fix EFI ACPI detection

lua was previously unable to determine ACPI presence because this
probing was postponed until the final loading and execution of the

This patch resolves that by detecting ACPI early (similar to
the order of operations in the legacy i386 loader).

Given that hints set this way don't work when a static kenv is compiled

such, we no longer hints.*, so remove them.

amd64 UEFI loader: stop copying staging area to 2M physical

On amd64, add a possibility to activate kernel with staging area in place.
Add 'copy_staging' command to control this. For now, by default the
old mode of copying kernel to 2M phys is retained. It is going to be
changed in several weeks.

On amd64, add some slop to the staging area to satisfy both requirements
of the kernel startup allocator, and to have space for minor staging data
increase after the final size is calculated. Add a new command
'staging_slop' to control its size.

Improve staging area resizing, in particular, reallocate it anew if
we cannot grow it neither down nor up.

stand/multiboot2: add support for booting a Xen dom0 in UEFI mode

Add some basic multiboot2 infrastructure to the EFI loader in order to
be capable of booting a FreeBSD/Xen dom0 when booted from UEFI.

Only a very limited subset of the multiboot2 protocol is implemented
in order to support enough to boot into Xen, the implementation
doesn't intend to be a full multiboot2 capable implementation.

Such multiboot2 functionality is hooked up into the amd64 EFI loader,
which is the only architecture that supports Xen dom0 on FreeBSD.

The options to boot a FreeBSD/Xen dom0 system are exactly the same as
on BIOS, and requires setting the xen_kernel and xen_cmdline options
in loader.conf.

stand/efi: allow not exiting boot services

Xen requires that UEFI BootServices are enabled in order to boot, so
introduce a new parameter to bi_load in order to select whether BS
should be exited.

stand/efi: allow not exiting boot services

Xen requires that UEFI BootServices are enabled in order to boot, so
introduce a new parameter to bi_load in order to select whether BS
should be exited.

No functional change introduced in this patch, as all current users of
bi_load request BS to be exited. Further changes will make use of this
functionality.

Note the memory map is still appended to the kernel metadata, even
when it could be modified by further calls to the Boot Services, as it
will be used to detect if the kernel has been booted from UEFI.
