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.

Introduce support for HW watchpoints and single stepping for ARMv6/v7
Allows for using hardware watchpoints for 1, 2, 4, 8 byte long addresses.
The default configuration of watchpoint is RW but code allows to select
RO or WO and X.
Since debugging registers are per-CPU (CP14) the watchpoint is set on
the CPU that was lucky (or not) to enter DDB.
HW breakpoints are used to perform single step in KDB.
When HW breakpoint is enabled all watchpoints are temporary disabled
to avoid recursive abort on both watchpoint and breakpoint.
In case of branch, the breakpoint is set to both - next instruction
and possible branch address. This requires at least 2 breakpoints
supported in the CPU however this is a must for ARMv6/v7 CPUs.

Fix cp15 PAR definition and function. While here, add cp15 ATS1CPW
function which checks an address for privileged (PL1) write access.
The function is inlined so it does not bring any cost, but makes
function set for checking privileged access complete.

access functions in the generic timer driver.

Add accessors for the ARM CP15 performance monitor registers. Also ensure
that some #ifdef SMP code is also conditional on __ARM_ARCH >= 7; we don't
support SMP on armv6, but some drivers and modules are compiled with it
forced on via the compiler command line.

Add machine/sysreg.h to simplify accessing the system control coprocessor
registers and use it in the ARMv7 CPU functions.
The sysreg.h file has been checked by hand, however it may contain errors
with the comments on when a register was first introduced. The ARMv7 cpu
functions have been checked by compiling both the previous and this version
and comparing the md5 of the object files.
