jtag_add_dr/ir_scan() now takes the tap as the first
argument, rather than for each of the fields passed
in.
The code never exercised the path where there was
more than one tap being scanned, who knows if it even
worked.
This simplifies the implementation and reduces clutter
in the calling code.
use jtag_add_ir/dr_plain_scan() for more fancy situations.

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.

For some routines that only returned ERROR_OK and where the
caller never checked ... don't bother. Remove some noise,
and bugfix some comments.

Use the DPM watchpoint support; remove old incomplete stubs.

No point in both ARM11 and Cortex-A8 having private copies
of the logic sorting out e.g. DBG_REASON_WATCHPOINT.
Add and use a shared routine for this ... there's actually
a bunch more debug entry logic that could be shared, this
is just a start on that. Note that this routine fixes a
bug observed in the ARM11 code, where some abort mode quirks
were displayed as being an unknown debug reason; and also
silences needless ARM11 chatter.
Likewise with private copies of DSCR ... add one to the DPM
struct. Save it as part of setting DBG_REASON_* so later
patches can switch over to using that copy.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "arm11.h"
the following form should be used.
#include <target/arm11.h>
The exception is from .c files in the same directory.

Just store a clean copy of DSCR in the per-CPU struct, so we
trivially pass a pointer to a recent copy. This replaces the
previous "last_dscr" and cleans up most of the related calling
conventions ... but it doesn't remove the other DSCR copy.

Move the initial breakpoint/watchpoint disable calls to
arm_dpm_initialize(), and start using that routine. This
split helps with arm11 support.

This is a very thin layer over some of the current ARM11
debug TAP utilities. The layer isn't yet hooked up.

For now there's no point in saving this stuff after examine()
checks it out as OK. Ditto exporting symbols that aren't
used outside of the module which defines them. In fact, those
two things needlessly complicate the code...
