AT91SAM4L: handle reset run/halt in SMAP
This is a remake of http://openocd.zylin.com/1966
originally written by Angus Gratton <gus@projectgus.com>
ATSAM4L has a "System Manager Access Port" (SMAP) that holds the CPU
in reset if TCK is low when srst (RESET_N) is deasserted.
Without this change any use of sysresetreq or srst locks the chip
in reset state until power is cycled.
A new function smap_reset_deassert is called as reset-deassert-post event handler.
It optionally prepares reset vector catch and SMAP reset is released then.

This patch might influence openocd Tcl commands behaviour in subtle
ways, please give it a nice testing.
The idea is that if an OpenOCD Tcl command returns an error, an
exception is raised, and then the return code is propogated all the
way up (or to the "catch" if present). This allows to detect
"shutdown" which is not actually an error but has to raise an
exception to stop execution of the commands that follow it in the
script.
openocd_thread special-cases shutdown because it should then terminate
OpenOCD with a success error code, unless shutdown was called with an
optional "error" argument which means terminate with a non-zero exit
code.
