ddb: Remove useless includes

systm.h was included for boothowto here, but it's not used here, so drop
this include. Also sys/cdefs.h isn't needed, drop it too.

arm: pmap_extract() returns a PA not a boolean value

Assume a PA of 0 indicates an invalid virtual address.

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

Remove /^[\s*]*__FBSDID\("\$FreeBSD\$"\);?\s*\n/

arm: Use C89 function declaration for db_read_bytes.

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.

arm: clean up empty lines in .c and .h files

Use our nitems() macro when param.h is available.

Replacements specific to arm, mips, pc98, powerpc and sparc64.

Use kernel_pmap directly instead of pmap_kernel(). The kernel_pmap is
already used for __ARM_ARCH >= 6 and so even for __ARM_ARCH < 6 on some
common places.

Add support for branch instruction on armv7 with ptrace single step

Previous code supported only "continuous" code without any kind of
branch instructions. To change that, new function was implemented
which parses current instruction and returns an addres where
the jump might happen (alternative addr).
mdthread structure was extended to support two breakpoints
(one directly below current instruction and the second placed
at the alternative location).
One of them must trigger regardless the instruction has or has not been
executed due to condition field.
Upon cleanup, both software breakpoints are removed.

This implementation parses only the most common instructions
that are present in the code (like 99.99% of all), but there
is a chance there are some left, not covered by the parsing routine.
Parsing is done only for 32-bit instruction, no Thumb nor Thumb-2
support is provided.
