The add_usage_text command uses the same C handler, which was updated
to support its new polymorphic role. This patch updates the two script
commands that needed this support: 'find' and 'script'.
Rewrite means for scripts to register help text for commands. These
cause the new commands to be stored in the command heirarchy, with
built-in commands; however, they will never be invoked there because
they do not receive a command handler. The same trick is used for
the Jim commands.
Remove the old helpers that were used to register commands.
Rewrites 'help' command in C, using new 'cmd_help' for display. Adds the
built-in 'help' COMMAND_HANDLER to provide better output than the
TCL-based script command (e.g. heirarchical listing of commands).
The help string is stored in the command structure, though it conitnues
to be pushed into the Jim environment. The current idiomatic usage
suggests the addition of a usage field as well, to provide two levels
of detail for users to consume (i.e. terse usage list, or verbose help).
Creates a helper function, cmd_help, which displays the help string
for a single command. Presently, it is called from the loop in help.
The routine has been extended to allow indentation of command groups,
so an improved help command can improve the display of information.
Moves definitions for each layer into their own file, eliminating
layering violations in the built-in TCL code. Updates src/Makefile.am
rules to include all files in the final startup.tcl input file, and
others Makefile.am rules to distribute the new files in our packages.
Rename the "armv4_5" command prefix to straight "arm" so it makes
more sense for newer cores. Add a simple compatibility script.
Make sure all the commands give the same "not an ARM" diagnostic
message (and fail properly) when called against non-ARM targets.

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 way out of date; hopeless to keep that current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.

This abstracts the "jtag arp_init-reset" call into a method
called from OpenOCD startup and reset processing.
Platforms which have different requirements for how such hard
resets must be performed can now override "init_reset" instead
of needing to rebuild custom hacked versions of the server.

make sure that when there are two or more targets, their
various pre/post event reports are correctly ordered.
Previously, only the first target always saw its "pre"
method before SRST was asserted or deasserted.

Let disabled targets be ignored during normal operation:
- In target_examine(), ignore disabled TAPs
- Reset handling must not poke at them either:
* fail $target_name arp_* operations on disabled TAPs
* in startup.tcl, don't even issue the arp_* wait ops
ZW: removed superfluous braces from the patch to target.c.

messages a bit. The file and line # of the syntax error
in a reset script is now printed.

from pre/post_reset event scripts. Adding the second parameter was
a mistake seen in retrospect. this gives precise control in post_reset
for *when* the post reset speed is set. The pre_reset event was
added *after* the second parameter to jtag_khz/speed
- the target implementations no longer gets involved in the reset mode
scheme. Either they reset a target into a halted mode or not.
target_process_reset()
detects if the reset halt failed or not.
- tcl target event names are now target_N_name. Mainly internal
at this early stage, but best to get the naming right now.
- added hardcoded reset modes from gdb_server.c. I don't know precisely what
these defaults should be or if it should be made configurable. Perhaps some
hardcoded defaults will do for now and it can be made configurable later.
- bugfix in cortex_m3.c for reset_run_and_xxx?
- issue syntax error upon obsolete argument in target command instead of
printing message that will surely drown in the log
