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.

In some circumstances (e.g. inappropriate jtag clock)
target_write_memory in lpc2000_iap_working_area_init might fail. The
allocated working area should be freed inside
lpc2000_iap_working_area_init in this error case.
This was leading to a weird segfault due to stack corruption later
when reset was executed.

Calling ahbap_debugport_init() is wrong here because the actions
performed by it might lead to jtagdp_transaction_endcheck errors thus
leading to infinite recursion.
The removed code is not needed now because target polling should lead
to reexamination automatically, and both cortex_a and cortex_m call
ahbap_debugport_init() as part of their target examine handler.
This was reported as a real life issue on IRC by Weaselweb with
Cortex-A target. Quitte reports similar results in some circumstances
(adapter_khz too high) with LPC17xx.

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.

The original code had iterated 10,000,000 times and taken the elapsed
time divided by 10,000, to yield kHz which is mathematically correct
only if we were measuring time in seconds, but we are measuring time in
milliseconds, so the correct divisor is actually 10,000,000. Previous
code would report 0.500 for actual measured speed of 500 kHz.

This should allow most of the existing configurations for older
versions to remain compatible without forcing the user to change his

Also in some circumstances can remove the need to chain a "-c transport
select X" when building custom configs on the command line, which seems
like a common new user pitfall.

This brings SWD reconnection procedure in line with the ARM

The motivation behind this patch is to make SAM4L "reset" and "reset
halt" properly without SRST. The complication here is that EDBG issues
an additional read of DP_RDBUFF automatically right after writing
SYSRESETREQ, that leads to a FAULT which needs to be dealt with
properly. With this patch the very first ahbap_debugport_init DAP
access will make SWD layer properly reinitialise the link before
continuing.
