bsd.own.mk: rename GCC_NO_* to CC_WNO_*

Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.

GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

Add HAVE_ACPI and HAVE_UEFI flags to bsd.own.mk and use them to
conditionally include ACPI and UEFI bits instead of relying on adhoc
MACHINE_ARCH tests.

Build acpi tools and iasl on aarch64eb, and fix set lists for MKDEBUG.

introduce some common variables for use in GCC warning disables:

GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)

use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.


we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

Add acpidump, amldb, and iasl to aarch64 build.

branches: 1.4.14; 1.4.16;
Define _KERNTYPES for things that need it.

Convert more MACHINE tests to MACHINE_ARCH

branches: 1.2.20;
only build on i386 and amd64.

Add acpitools

fix multiplei repetitive typos in comments, messages and documentation. mainly because copy paste code big amount of files are affected.

Remove workaround for ancient HTML generation code.

Merge riastradh-drm2 to HEAD.

Use Mt for email addresses.

branches: 1.4.6; 1.4.12; 1.4.16;
Escape literal backslashes.

branches: 1.3.8; 1.3.14;
Convert a simple tbl(1) table (which wasn't being formatted)
into a .Bl -tag.

branches: 1.2.4; 1.2.8;
New sentence, new line.
Sort sections.
Fix a typo.
Comment out xref to acpiconf(8), which we don't have.
Use HTML macros.

Add acpitools

mmap MAP_FAILED audit.

getopt returns int, not char

branches: 1.3.40; 1.3.42;
Use __dead.

Now compiles on amd64, mostly due to %llx -> %PRIx64, but also changing some
internal structures around. (yay for assuming that pointers can be held in
an int. bah.)

Not sure if it actually _works_ on amd64, but as the output on my i386
doesn't change pre/post-patching, that seems good enough for now.
