Add missing COMMAND_REGISTRATION_DONE.
For now the command syntax for zy1000 needs to be compatible
across 0.3/0.4, the world outside OpenOCD interfaces to
zy1000 using the old syntax. Post 0.4 release(0.4.1 even)
I'll switch to subcommand scheme.
Switch to subcommands post 0.3 lifecycle.

Splits bulk of the jtag_tap_configure into jtag_tap_configure_event,
removing three or four levels of indentation in the process.
The resulting code was stylistically improved in other ways, but it
should be functionally identical.
Moves the tertiary jim handlers and required static helpers to the top
of tcl.c, defining them in a new registration array that is chained in
both the top-level context and under the jtag command. The top-level
commands can be removed at some point in the future to reduce clutter.
Explodes the 'jtag' into separate command handlers, which are easier
to understand and extend. Makes the code much easier to understand,
though further simplifications are possible. This patch tries to
minimize the noise when viewed with 'git diff -w'.
Gives these commands improved built-in help and usage information.
Removes hello and foo commands from top-level registration. Instead,
the dummy interface driver and faux flash driver have been augmented
to register these commands as sub-commands.
Adding jim_handler field to command_registration allows removing the
register_jim helper. All command registrations now go through the
register_command{,s}() functions.
Changes the jtag_interface->register_callbacks field to a list of
commands to be registered. Changes callback to invocation of
register_commands() with that command registration list. Removes all
JTAG interface driver register_command callback functions, which the
previous commits had converted into identical calls.
Use register_commands() with command registration array.

This module was broken by previous changes, but no one has complained.
Are there still users for this modules?
Rewrite rlink_init routine to use jtag_usb_open helper. Eliminates
some spurious calls to exit().
Wraps a tremendously long line of comment to fit 80 columns too.
Begins to consolidate code used by several USB JTAG interfaces.
This first patch provides the required build system changes and
a common jtag_usb_open routine, which will replace the guts for
probing the busses and devices for possible VID/PID matches.
The following patches convert each driver to use it.
Updates all command parsing of simple "enable" and "disable" arguments.
A few case in the tree use a tri-state or extended arguments, which
cannot use this simple macro.
Simlifies the xscale icache/dcache command handler logic.
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.
The code is now much more explicit. It flushes every
N writes. For now flush every time, but tinkering with
the bridge FIFO size and how often we flush clearly
points in the direction of the Avalon write FIFO full
being the culprit.

Shifting by more than 32 is undefined for 32 bit integers according
to the C standard. Robust solution is conditional code.
