retire obsolete mXY_phys commands. Handled by generic memory read/modify commands and target read/write physical memory callbacks.

Added target_read/write_phys_memory() fn's. mdX/mwX commands updated to support phys flag to specify bypassing of MMU.

Retire obsolete and superfluous implementations of virt2phys in each target. This is done in a polymorphic implementation in target.c

XSVF improvements:

 - Layer parts of XSVF directly over SVF, calling svf_add_statemove()
   instead of expecting jtag_add_statemove() to conform to the SVF/XSVF
   requirements (which it doesn't).

   This should improve XSTATE handling a lot; it removes most users of
   jtag_add_statemove(), and the comments about how it should really do
   what svf_add_statemove() does.

 - Update XSTATE logic to be a closer match to the XSVF spec.  The main
   open issue here is (still) that this implementation doesn't know how
   to build and submit paths from single-state transitions ... but now
   it will report that error case.

 - Update the User's Guide to mention the two utility scripts for
   working with XSVF, and to mention the five extension opcodes.

Handling of state transition paths is, overall, still a mess.  I think
they should all be specified as paths not unlike SVF uses, and compiled
to the bitstrings later ... so that we can actually make sense of the
paths.  (And see the extra clocks, detours through RUN, etc.)

Removed unused interface_jtag_set_end_state and wrote down some notes on TCP/IP client/server scheme.

Don't add extra TCK in current state; exit from RESET had four extras.
Only IDLE --> IDLE needs such an extra clock.  (At least one TCK must
be issued.)

Allow entry to RESET; SVF allows it, so must we (despite those entries
being commented out of the statemove table).

When entering RESET, always use TLR ... we might end up with extra clocks
in reset that way, which is harmless, but we'll never end up in any other
state than RESET, which is useful paranoia.

Lightly tested on dm365.

As decided a while back, this isn't a transition we want to chance.
Whenever someone wants to got to RESET, force it.

SVF: comment the predefined/default paths; make them static const

SVF, XSVF: whitespace fixes, mostly so copyrights display sanely

This is unfortunately needed to make stdio work like OpenOCD expects -- matching
the ANSI-C standard, instead of MS-Windows.

I tested it in both MinGW-W64 on Vista 64 and MinGW-W32 on XP, and I don't
see any adverse effects to enabling it for all MinGW versions.

After reading a bit further, it appears that ws2_32 (Windows Sockets 2)
is included in all versions of Windows and backwards compatible with
wsock32, at least according to

 http://msdn.microsoft.com/en-us/library/ms740673%28VS.85%29.aspx.

Only Win95 seems to require a manual installation; is not a big deal.

So I think we can drop this whole business of detecting 64 bit MinGW and
just use -lws2_32 for all MinGW platforms.

Same requirement as like init_reset, and for the same reason:
we need to start with a known and working state.

Without this fix, the following code cannot be single stepped:

	add	ip, pc, #1
	bx	ip
	[thumb code here]

Compilation on cygwin, using gcc v3 with option -mno-cygwin,
currently produces a large number of the following warnings:

   warning: `gnu_printf' is an unrecognized format function type

These have been introduced with the recent MinGW GNU C99 printf
compliance patch, as gnu_printf was only introduced with gcc v4.4
and is not recognized with earlier versions.

The attached fix adds gcc version detection to the previous patch
to avoid the problem.

Assign to "intptr_t", which on some versions of MS-Windows
will widen the variable; then cast to HANDLE.

On Windows the name is "bin2char.exe".
All operating systems now have "xscale_handler.h".

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".

Use JIM_WIDE_MODIFIER for the sscanf format, and apply it for MINGW32 as
well as other Windows environments.  (Microsoft doesn't conform to the
C99 standard, and uses "%I64d" not "%lld" for "long long".)

NB: __MINGW32__ should work on both w32 and w64,.

Work better when building outside the source tree.

Generate a C struct with the data, and use that, instead of an
assembly language file.  The assembly language causes issues on
Darwin and MS-Windows, which don't necessarily use GNU AS; or
if they do, don't necessarily use its ELF syntax.

It's also better in two other ways:  fewer global symbols; and
the init-time size check gets optimized away at compile time.
(Unless it fails, in which case bigger chunks of the file vanish.)

Just use "%p" instead of consing up some integral type for pointer printf.

Based on some patches from <redirect.slash.nil@gmail.com>
for preliminary Win64 compilation.  More such updates are
needed, but they need work.  Compile tested on 64 and 32 bit
Linuxes, and Cygwin.

This makes the documentation a closer match to "help" output:

 - "pathmove" somehow was not documented in the User's Guide

 - "jtag_nsrst_assert_width" and "jtag_ntrst_assert_width"
   are new; both needed descriptions.

 - Removed two undocumented and fairly useless script mechanisms:
    * production/production_info/production_test ... using it,
      requires replacing everything; so having it adds no value.
    * cpu ... way out of date; hopeless to keep that current

Note that anyone using that "production" stuff already defines
their own procedures, and can keep using them with no change.
