moves handling of problems with resetting into the halted state
into the target implementation.
Also target_process_reset() is now simpler and has error handling,
e.g. if assert reset fails, then target_process_reset() will propagate
that error.
cmd_ctx was passed in to examine(), which is wrong - removed that.
