Fix a bunch of typos.
Most are in code comments, so nothing should break. UNKOWN_COMMAND and
CMD_UNKOWN are not used elsewhere, so correcting the spelling should
also not break anything.

min_time was effectively ignored, I needed it to program a Lattice MachXO
which uses a RUNTEST to wait for an erase operation, amongst other things.
With this patch pauses happen and I can program the device with an SVF
generated in LSC ispVM (with "Rev D Standard" checked to suppress
nonstandard LOOP statements)

them all to a common.mk.

Globally rename "jtag_khz" as "adapter_khz", and move it out of the "jtag"
command group ... it needs to be used with non-JTAG transports
Includes a migration aid (in jtag/startup.tcl) so that old user scripts
won't break. That aid should Sunset in about a year. (We may want to
update it to include a nag message too.)

These fn's now clearly just clock out/in bits. No mystical

jtag_add_dr/ir_scan() now takes the tap as the first
argument, rather than for each of the fields passed
in.
The code never exercised the path where there was
more than one tap being scanned, who knows if it even
worked.
This simplifies the implementation and reduces clutter
in the calling code.
use jtag_add_ir/dr_plain_scan() for more fancy situations.

isspace() parameter must be an integer, else a 'char' gets
used as an array index (sigh).

More SVF fixes:
* Treat all content between parentheses as part of the same
parameter; don't (wrongly) treat whitespace as a delimiter.
* Use isspace() to catch that whitespace; it's not all single
spaces, newlines etc are also valid.
* When parsing bitstrings, strip leading whitespace too.
So for example, these are equivalent and should (now) be OK:
"TDI( 1234 )"
"TDI( 1 2 3 4 )"
"TDI(00 12 34 )"
"TDI(
00 12
34)"

See http://forum.sparkfun.com/viewtopic.php?p=90983#90983 for discussion;
basically, the SVF parser wrongly expects "TDI (123)" but the space is
optional and it should accept "TDI(123)" too.
In the same way, "TDI(123)TDO(456)" should work too.
Rather than update the command parsing, this just makes sure the expected
spaces are present.

Usage messages should use the same EBNF as the User's Guide;
no angle brackets. Be more complete too ... some params were
missing.
Don't use "&function"; its name is its address.

It's less accepting of signed char ... insisting that e.g. tolower()
not receive one as a parameter.
It's probably good to phase out such usage, given the number of bugs
that lurk in the vicinity (assumptions that char is unsigned), so fix
these even though such usage is actually legal.

Changes from the flat namespace to heirarchical one. Instead of writing:
#include "jtag.h"
the following form should be used.
#include <jtag/jtag.h>
The exception is from .c files in the same directory.

- Use the name mappings all the other code uses:
+ name-to-state ... needed to add one special case
+ state-to-name
- Improve various diagnostics:
+ don't complain about a "valid" state when the issue
is actually that it must be "stable"
+ say which command was affected
- Misc:
+ make more private data and code be static
+ use public DIM() not private dimof()
+ shorten the affected lines
Re the mappings, this means we're more generous in inputs we
accept, since case won't matter. Also our output diagnostics
will be a smidgeon more informative, saying "RUN/IDLE" not
just "IDLE" (emphasizing that there can be side effects).

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.
