Paul Fertser f02327d859 server: add safeguards against printing bogus port number
Clang static checker emits "Assigned value is garbage or undefined"
warning there as it can't prove that when the socket descriptor is
AF_INET/SOCK_STREAM and getsockname doesn't return an error, sin_port
is guaranteed to be filled in.

Pacify it by obvious means.

Tim Newsome 79cbeafe9f Support listening on port 0.
When listening on port 0, the system will assign a random open port. We
use this to run multiple OpenOCD instances against multiple simulators
as part of regression testing. This mechanism means the various test
instances don't have to coordinate to ensure they don't reuse any ports.

The required changes are minimal:
1. Don't increment the port number when it's 0.
2. Print out which port was assigned by the system.

This patch does not affect the default behavior to listen on all

Paul Fertser 19f219f731 Tcl exception codes cleanup, shutdown command amendments
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.

This should facilitate dynamic target creation and removal.

Currently it helps with getting 0 bytes lost report from Valgrind on
exit (after talking to a nucleo board). However, 1,223,886 bytes in
5,268 blocks are still reachable which means the app holds pointers to
that data on exit. The majority comes from the jtag command queue,
there're also many blocks from TCL command registration.
