acpica: Quiet a -Wdangling-pointer warning in AcpiUtInitStackPtrTrace.

This function intentionally saves a pointer to an on-stack variable in
a global as a dubious way of reading the stack pointer.

acpica: Merge ACPICA 20221020

Remove tests for obsolete compilers in the build system

Assume gcc is at least 6.4, the oldest xtoolchain in the ports tree.
Assume clang is at least 6, which was in 11.2-RELEASE. Drop conditions
for older compilers.

Add explanatory comment for r327622: clang 6.0.0 and higher warn about
the ACPI_ROOT_OBJECT and ACPI_TO_POINTER macros from acpica's actypes.h
header, that they use arithmetic on a null pointer treated as a cast
from integer to pointer, which is a GNU extension. We turn off the
warning, because this is in contributed code.

Requested by: rakuco

Revert r327338, undoing the changes to the ACPI_ADD_PTR and ACPI_SUB_PTR
macros. Instead, turn off clang 6.0.0 warnings about null pointer
arithmetic in usr.sbin/acpi/acpidb instead.

Convert usr.sbin to LIBADD
Reduce overlinking

Fix declarations to slightly increase WARNS level.

Remove unused ACPICA sources from userland makefiles.

Allow ACPI module build on amd64. Although we strongly recommend building

- Allow users to enable dumping Debug objects without ACPI debugger.
Setting the new sysctl MIB "debug.acpi.enable_debug_objects" to a non-zero
value enables us to print Debug object when something is written to it.
- Allow users to disable interpreter slack mode. Setting the new tunable
"debug.acpi.interpreter_slack" to zero disables some workarounds for common
BIOS mistakes and enables strict ACPI implementations by the specification.

MFC: r204920
Since the interpreter slack mode is a tunable now, enable a local hack only
when it is set. Note the default behaviour does not change by this change.

Merge ACPICA 20100331 (and four additional upstream patches).

Create the altix project branch. The altix project will add support
for the SGI Altix 350 to FreeBSD/ia64. The hardware used for porting
is a two-module system, consisting of a base compute module and a
CPU expansion module. SGI's NUMAFlex architecture can be an excellent
platform to test CPU affinity and NUMA-aware features in FreeBSD.

- Import the HEAD csup code which is the basis for the cvsmode work.

These are the things that the tinderbox has problems with because it
doesn't use the default CFLAGS which contain -fno-strict-aliasing.

Until the code is cleaned up, just add -fno-strict-aliasing to the
CFLAGS of these for the tinderboxes' sake, allowing the rest of the
tree to have -Werror enabled again.

Add suspend/resume support to the debugger.

Remove the band-aid to make these compile on amd64/ia64.

Apparently I limited my testing of the ductape and bubblegum solution
to acpidb. The same problem exists in iasl. Add JIT patching there
too.
Add a comment to both makefiles to increase the chance that both
kludges are removed when a real solution is committed.

Perform first-aid: unbreak the build for amd64 and ia64 by patching
osunixxf.c on the fly. This avoids having to pull it from the vendor
branch or otherwise pollute the repository with new short-lived files.

This should hold until the real fix arrives.

Add the acpidb and iasl utilities. This is not yet hooked up to the build.
