- Moves references to global jtag interface to default core implementation.
- Missed this reference in the earlier "pointless" patch. Mea culpa.
Important: this has a side-effect. Previously, the error return inside
the interface routine short-circuited the remainder of that function
when 'init' has not been called. With this patch, the command queue
will be cleared in the case that 'init' has been called. Since that
case indicates a buggy script, this does not seem to be a problem.

- Add jtag_callback_queue_reset() to reset the callback queue.
- Make interface_jtag_execute_queue() use new helper function.

- Make interface_jtag_execute_queue call new helper function.
- Add default_interface_jtag_execute_queue to wrap jtag interface access.
This patch may look useless on its own, but it helps to isolate the core
JTAG variables from the interface_jtag_* routines, so the later can be
moved into jtag_driver.c in a pending patch.

- Rename last_command_pointer as next_command_pointer, because this variable
stores the address where jtag_queue_command() will store a command pointer.
- Make that variable static, since it is only used internally in jtag.c.
- Remove superfluous accessor for that now-static variable.
- Deobfuscate use of variables in jtag_command_queue.
- Add jtag_command_queue_reset helper function.
- Use it in interface_jtag_execute_queue.

- Factor jtag_add_scan_check to call new jtag_add_scan_check_alloc helper.
- Use conditional logic to define two versions of the helper.
- These helpers will be moved to other files in future patches.

Make the TCL "drscan" and "irscan" commands finish in RUN/IDLE
unless the user specifies otherwise ... usually they'd choose
something like DRPAUSE or IRPAUSE, avoiding RUN/IDLE.
The current "end" state is whatever the preceding commands left
in "cmd_queue_end_state", which to TCL scripts isn't knowable.
This change should forestall various surprises/bugs.
Also check that any "end" state specified is safe in case this
adapter's JTAG clock is free-running. For now, just issue a
warning; eventually a hard failure is probably correct.

Make it so the magic "reset_config" keywords can be provided in any
order. This eliminates needless error paths, and makes it easier
to define things at the right level (adapter, board, target).
It also includes two other behavioral changes:
(1) When "handle_reset_config" sees a parameter error, it
exits without changing anything. This is best viewed
as a bugfix. (Old behavior: restore defaults, even if
they weren't previously active.)
(2) Only the behaviors that were explicitly specified get
changed. (Old behavior: everything else gets reset to
the "default".) So for example you can now specify SRST
drive requirements without saying anything about the
three unrelated topics you previously had to specify.
That second one might cause confusion for any configs that end
up calling "reset_config" twice, so it will deserve to be called
out in the release notes. (There were no such configurations in
the current OpenOCD source tree.)
Update docs accordingly. Note that at least some versions of
the texi-to-html tools can't handle "@xref{with spaces}", but
those work properly in PDF and in the info files.

Doc (mostly) update for jtag_khz:
- switch to @deffn syntax
- add entry for "jtag_rclk"
- move deprecated "jtag_speed" into collection of deprecated calls
And for ft2232, don't be the only adapter to *log* an error if RTCK
is requested; it's already reported properly, like any other nonfatal
command parameter. "jtag_rclk" just works as expected, without any
scarey messages.

- Add jtag_execute_queue in jtag_add_reset after interface_jtag_add_reset.
- Use tap_set_state to demark TAP_RESET, instead of cmd_queue_cur_state
- cmd_queue_cur_state needs to be retired.
