- jtag_khz/speed are now single parameter only. These are used

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
