Also set MACHINE and MACHINE_ARCH when reading config options from
src.opts.mk. This ensures any machine-dependent options are reported
correctly.

arm64: Check DMAP address is valid in PHYS_IN_DMAP
When checking if a physical address is in the DMAP region we assume
all physical addresses between DMAP_MIN_PHYSADDR and DMAP_MAX_PHYSADDR
are able to be accesses through the DMAP. It may be the case that
there is device memory in this range that shouldn't be accessed through
the DMAP mappings.
Add a check to PHYS_IN_DMAP that the translated virtual address is a
valid kernel address. To support code that already checks the address
is valid add PHYS_IN_DMAP_RANGE.

arm64/vmm: Ensure the tlbi has completed
Ensure the TLB is invalidated before enabling the EL2 MMU. Without
this the TLB may be in an inconsistant state leading to a possible
exception when enabling the MMU.

Cirrus-CI: bump Clang versions to 16 and 17
Clang/LLVM 17 is currently the in-tree default compiler, so use it as
the default Cirrus-CI toolchain. Clang/LLVM 18 is coming soon and needs
to be added here, but I ran into trouble with llvm18-lite package
availability so will look at that later.

acpi_battery: avoid divide-by-zero when no devices have capacity info
On laptops with builtin batteries, disconnecting the battery may show up
as a battery without any capacity information. (The theory is that one
is disconnecting the cells but the electronics identifying the battery
are still connected.) As a result, the loop over all batteries in
acpi_battery_get_battinfo results in total_lfcap == 0.
So, just check that total_lfcap is non-zero to avoid a division by zero
(triggerable by sysctl hw.acpi.battery).

bhyve.8: Remove mention of the -A flag
It is a no-op on amd64 now and is not implemented on arm64, so let's
remove mention of it altogether so as to reduce confusion for arm64
users.

udf: uma_zcreate() does not fail
While here remove an old comment regarding preallocation; it appears to
refer to an optimization that is almost certainly irrelevant at this
point.
No functional change intended.
