For the time being I propose this way of dealing with RTOSes that do
not export necessary information on their own.
I also suggest implementing a similar scheme for ChibiOS, exporting
the necessary struct fields' offsets via an OpenOCD-specific helper.

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.

Some targets need arbitrary amount of time (usually not too long)
after reset (both sysresetreq and srst) to do initialisation, and
SWD/JTAG is not available during that. According to PSoC4 docs, the
debugger should try connecting until it succeeds.
Also ahbap_debugport_init might be necessary to perform after using
hardware srst too, so add it there (except for the targets that
support srst_nogate since they are very unlikely to need it).

In some cases (the most obvious are TI's SoCs) ROM table lacks entries
for the cores, so OpenOCD has no way to determine what debug base to
use. Due to an error fixed in ec9ccaa288 it wasn't handled properly,
and OpenOCD would continue to try using dbgbase = 0, which happened to
work for e.g. AM437x.
This patch adds a clear indication to the user that to access such a
target, dbgbase must be set manually in the config.

The removed code is not needed now because target polling should lead

The IAP working area needs to be freed here, just like in all the
other driver functions since an automatic local variable is used to
store a pointer to it.
This was reported by quitte (Jonas Meyer) on IRC as a strange totally
unrelated segfault after doing certain operations (leading to target
reset) from GDB. He has provided me with remote access to the specific
machine and configuration that exposed the issue, and after some
debugging it became apparent that a auto local variable (holding the
gdb connection pointer) gets overwritten somehow. Placing an
appropriate breakpoint just before the event and using a watchpoint
made the cause apparent: reset lead to freeing of all working areas,
and there was one holding a pointer to a variable that was auto local
in get_lpc2000_part_id().

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.

1. The function is not designed to be reentrant but a nested call is
possible via: target_handle timer event -> poll -> target events
before/after reexaminantion -> script_command_run ->
target_call_timer_callbacks_now . This patch makes function a no-op
when called recursively;
2. The current code can deal with the case when calling a handler
leads to its removal but not when it leads to removal of the next
callback in the list. This patch defers actual removal to consolidate
it with the calling loop.

instead of having both double and single presicion registers in the

split the data in halves whenever needed.
Tested with HLA only (on an STM32F334 disco board).
Currently this patch makes all ARMv7-M targets report an FPU-enabled
target description to GDB. It shouldn't harm if the user is not trying
to access non-existing FPU. However, the plan is to make this depend
on actual FPU presence later.
