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 way out of date; hopeless to keep that current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.

Load the XScale debug handler from the read-only data section
instead of from a separate file that can get lost or garbaged.
This eliminates installation and versioning issues, and also
speeds up reset handling a bit.
Plus some minor bits of cleanup related to loading that handler:
comments about just what this handler does, and check fault codes
while writing it into the mini-icache.
The only behavioral changes should be cleaner failure modes after
errors during handler loading, and being a bit faster.
NOTE: presumes GNU assembly syntax, with ".incbin"; and ELF,
because of the syntax of the ".size" directive.

Streamline/shrink some needless JTAG stuff:
- Use #defines for the JTAG instructions; they can't ever change
- Remove an unused (!) shadow of tap->ir_length
- Stop using a copy of target->tap
- Don't bother saving the variant after sanity checking ir_length
Also, make target_create() work as on other targets: build the
register cache later, making init_target() no longer be a NOP.
Handle malloc failure; remove a comment that was obsoleted by the
not-so-new target syntax.

Just fill out the rest of the cache line with NOPs; don't change
the record of how much data we consumed. Otherwise the count of
how much data is left can roll over from positive to negative
("VERY positive") and skip the loop termination of zero.

Make most data static, and the tables readonly.

We added two overridable procedures; document them, and the
two jtag arp_* operations they necessarily expose.
Update the comment about the jtag_init_reset() routine; it's
been obsolete for as long as it's had SRST support.

Startup now mostly works, except that the initial target state
is "unknown" ... previously, it refused to even start.
Getting that far required fixing the ircapture value (which
can never have been correct!) and the default JTAG clock rate,
then providing custom reset script.
The "reset" command is still iffy. DCSR updates, and loading
the debug handler, report numerous DR/IR capture failures.
But once that's done, "poll" reports that the CPU is halted
(which it shouldn't be, this was "reset run"!), due to the
rather curious reason "target-not-halted".
Summary: you still can't debug these parts, but it's closer.
