Get rid of needless and undesirable code duplication for
all the DAP commands (resolving a FIXME) ... there's no
need for coreas to have private copies of that stuff.
Stick a pointer to the DAP in "struct arm", letting common
code get to it.
Also rename the "swjdp_info" symbol; just call it "dap".
This is an overall code shrink.

Move semihosting cmd to the arm cmd group.
Targets that support semihosting will setup the
setup_semihosting callback function.

Keep a handle to the PC in "struct arm", and use it.
This register is used a fair amount, so this is a net
minor code shrink (other than some line length fixes),
but mostly it's to make things more readable.
For XScale, fix a dodgy sequence while stepping. It
was initializing a variable to a non-NULL value, then
updating it to handle the step-over-active-breakpoint
case, and then later testing for non-NULL to see if
it should reverse that step-over-active logic. It
should have done like ARM7/ARM9 does: init to NULL.

This sets up a few of the core "struct arm" data structures so they
can be used with ARMv7-M cores. Specifically, it:
- defines new ARM core_modes to match the microcontroller modes
(e.g. HANDLER not IRQ, and two types of thread mode);
- Establishes a new microcontroller "core_type", which can be
used to make sure v7-M (and v6-M) cores are handled right;
- adds "struct arm" to "struct armv7m" and arranges for the
target_to_armv7m() converter to use it;
- sets up the arm.core_cache and arm.cpsr values
- makes the Cortex-M3 code maintain arm.map and arm.core_mode.
This is currently set up as a parallel data structure, primarily to
minimize special cases for the semihosting support with microcontroller
profile cores.
Later patches can rip out the duplicative ARMv7-M support and start
reusing core ARM code.

Make these ".h" files adopt the same policy the ".c" files already
follow: don't use <subsystem/...h> syntax for private interfaces.
If we ever get reviewed/supported "public" interfaces they should
come exclusively from some include/... directory; that'll be the
time to switch to <...> syntax for any subsystem's own interfaces.

The exception being declarations for drivers. Those should
be split out in some clean way -- like driver add/remove calls
made by initialization code -- but that's for another day.

Move most declarations in <target/armv4_5.h> to <target/arm.h>
and update users.
What's left in the older file is stuff that I think should be
removed ... the old register cache access stuff, which makes it
awkward to support microcontroller profile (Cortex-M) cores.
The armv4_5_run_algorithm() declaration was moved too, even
though it's not yet as generic as it probably ought to be.
