David Brownell 7556a93aed XSVF: use svf_add_statemove()
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.)

David Brownell 6907ef9d50 SVF: better spec conformance for STATE switch
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.

Redirect 'Slash' NIL fb61f52731 MinGW: always use "-D__USE_MINGW_ANSI_STDIO"
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.

Redirect 'Slash' NIL 0388a9c0e5 MinGW: use WinSock2
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.

Redirect 'Slash' NIL 113679ff59 corrective fix for MinGW GNU C99 printf compliance
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.

Redirect 'Slash' NIL 73349dc5ac More MinGW C99 printf compliance
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".

Redirect \"Slash\" NIL c9fbfbd95c jim-eventloop for MinGW-w64
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,.

David Brownell cb7965da15 xscale: better fix for debug_handler.bin
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.)

David Brownell bc792857a5 doc updates to match "help" better
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.
