sys: Remove $FreeBSD$: one-line .c comment pattern

Remove /^/[*/]\s*\$FreeBSD\$.*\n/

Remove the pre-ARMv6 and pre-INTRNG code.
ARM has required ARMV6+ and INTRNg for some time now, so remove
always false #ifdefs and unconditionally do always true #ifdefs.

De-pollute arm's sysarch.h.

Instead of including stdint.h for uintptr_t, include sys/_types.h and use
__types for everything that isn't a native C keyword type.

Remove the #include of cdefs.h. It appears after the include of armreg.h
which has a precondition of cdefs.h being included before it, so everyone
including sysarch.h is already including cdefs.h. (When armv5 support
goes away, there will be no need include armreg.h here either.)

Unfortunately, the unprefixed struct member names "addr" and "len" cannot
be changed, because 3rd-party software is relying on them (libcompiler_rt
is one known consumer).

sys/arm: further adoption of SPDX licensing ID tags.

sys/arm: further adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Include machine/acle-compat.h in cdefs.h on arm if the compiler doesn't
have ACLE support built in. The ACLE (ARM C Language Extensions) defines
a set of standardized symbols which indicate the architecture version and
features available. ACLE support is built in to modern compilers (both
clang and gcc), but absent from gcc prior to 4.4.

ARM (the company) provides the acle-compat.h header file to define the
right symbols for older versions of gcc. Basically, acle-compat.h does
for arm about the same thing cdefs.h does for freebsd: defines
standardized macros that work no matter which compiler you use. If ARM
hadn't provided this file we would have ended up with a big #ifdef __arm__
section in cdefs.h with our own compatibility shims.

Remove #include <machine/acle-compat.h> from the zillion other places (an
ever-growing list) that it appears. Since style(9) requires sys/types.h
or sys/param.h early in the include list, and both of those lead to
including cdefs.h, only a couple special cases still need to include
acle-compat.h directly.

Merge ^head r294090 through r294168.

Use __ARM_ARCH to decide when ARM_TP_ADDRESS needs to be set. This fixes
an issue with clang 3.8.0 where none of the __ARM_ARCH_*__ macros were
defined on some ARMv6 kernel configs.
