In the previous commit, we modified gdbstub.c to only send stop-reply
packets as a response to GDB commands that accept it. Now, let's add a
test for this intended behavior. Running this test before the fix from
the previous commit fails as QEMU sends a stop-reply packet
asynchronously, when GDB was in fact waiting an ACK.

There are a number of GDB's on various distros which fail fairly hard
when attempting to talk to a cross-arch guest. The previous attempt to
catch this was incorrect as the shell will deliver signals as 128+n.
Fix the detection and while we are it improve the logging we dump into
the test output.

device descriptions
Options such as "-gdb" or "-serial" accept a part-QemuOpts part-parsed-by-hand
character device description. Do not use short form boolean options in the
QemuOpts part.

This adds a new tests that allows us to test softmmu only features
including watchpoints. To do achieve this we need to:
- add _exit: labels to the boot codes
- write a memory.py test case
- plumb the test case into the build system
- tweak the run_test script to:
- re-direct output when asked
- use socket based connection for all tests
- add a small pause before connection

If gdb never actually connected with the guest we need to catch that
and clean-up after ourselves.

It seems older and non-multiarach aware GDBs might not fail gracefully
when faced with something they don't know. For example when faced with
a target XML for s390x the Ubuntu 18.04 gdb will generate an internal
fault and prompt for a core dump.
Work around this by invoking GDB in a more batch orientated way and
then trying to filter out between test failures and gdb failures.

The test runners job is to start QEMU with guest debug enabled and
then spawn a gdb process running a test script that exercises the
functionality it wants to test.

The aim of these tests is to combine with an appropriate kernel
image (with symbol-file vmlinux) and check it behaves as it should.
Given a kernel it checks:
- single step
- software breakpoint
- hardware breakpoint
- access, read and write watchpoints
On success it returns 0 to the calling process.
I've not plumbed this into the "make check" logic though as we need a
solution for providing non-host binaries to the tests. However the test
is structured to work with pretty much any Linux kernel image as it
uses the basic kernel_init code which is common across architectures.
