Don't expose the WDTR register through the register cache any
more. If anyone wants Tcl scripts to be able to use DCC based
communication with app code in the target, this wouldn't do it.
Bugfix: don't trust the Tcl-accessible version of DSCR to
flag whether WDTR needs to be restored when resuming.

This finishes the basic switchover to the new register code,
for everything except the debug registers. (And maybe we
shouldn't have a cache for *those* which works this way...)
The context save/restore code now uses the new code, but
it's in a slightly different sequence. That should be fine
since the R0/PC/CPSR stuff is all that really matters (and
if we can update those, we can update the rest).
Now there's no longer a way any code can be confused about
which copy of "r1" (etc) to use.

This was a private mechanism to snapshot registers before leaving
debug state, and then on reentry to optionally display what changed.
It was coupled to the private register cache, which won't be sticking
around in that form for much longer. Remove (instead of teaching
it how to handle *all* the registers).
(The idea is interesting, but we ought to be able to implement
this in a generic way. Ideally through Tcl scripts that can
automatically be invoked following debug entry...)

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...

Make this code look more like the rest of the OpenOCD code.
- Use calloc() directly, not NEW() ... and fix some potential
memory leaks while we're at it.
- Remove FNC_INFO ... it's a NOP that just clutters things,
and it's trivial for developers to add tracing as needed.
- Replace FNC_INFO_NOTIMPLEMENTED with LOG_WARNING calls;
ditto. And stop having those call sites wrongly succeed!
- Waste less space with the CHECK_RETVAL() macro.

We don't need to use size_t in these places; so it's easy
to be rid of the need for this #ifdef and its MS-derived
portability problems.

Minor cleanup of ARM11 register handling: remove disabled
register hooks. This should all be handled by shared code,
and this stuff is just clutter.

The ARRAY_SIZE macro was defined in several target files, so move it
to types.h.
This patch also removes two other identical macros: DIM (from jtag.h)
and asizeof (from arm11.h).
Three changes: remove ARM11_HANDLER() in favor of normal structure
initialization syntax; fix goofy indentation in that structure; and
don't needlessly export arm11_register_commands(), it's only called
through that method table.

These aren't desirable, given "standard" ETM support.
Also remove the now-unused arm11_find_target().

This will enable reusing many common ARM utilities, in
particular the ETM and ETB support. The ARM11 support
can still be much simplified after this patch, though.
Note: none of those common utilities kick in yet...

First cut of these commands. Øyvind tinkered a bit with
the number parsing to bring it up to speed + rebased it.
Ready for testing.

Reduces confusion about location of associated routines and
reduces clutter in the arm11 header.
Removes extra whitespace around the lines touched by these changes.
The quit entry point was not being invoked. Just a source
of confusion at this point. XScale ran 100x reset upon
quit, but that code made no sense, wasn't commented
and never invoke.

Passing "--std=gun99" is unfortunately not sufficient to make current
MinGW compilers conform with respect to checking printf format strings.
(The C runtime seems not to have problems.)
Fix by using a "gnu_printf" format specifier not "printf".
into the target implementation.
Also target_process_reset() is now simpler and has error handling,
e.g. if assert reset fails, then target_process_reset() will propagate
that error.
cmd_ctx was passed in to examine(), which is wrong - removed that.
