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.)

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.

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.
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.
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,.
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.)

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.

The LE check is obviously buggy (as easily triggered during some
testing), but I didn't audit the rest of the cases.

Cleanup comments and layout/whitespace in the TMS tables.
Table contents stayed the same (ignoring whitespace).

Resolve a "FIX" comment; yes that was superfluous given that the
JTAG core does that check by default. It was also buggy since it
wrote to a stack frame that went away before the write happened!!
Other fixes: remove pointless malloc(); zero-init scan_field_t
values wherever they appear; whitespace scrub; spelling fix.
