We already do a couple of "info registers" for specific tests but this
is a more comprehensive multiarch test. It also has some output
helpful for debugging the gdbstub by showing which XML features are
advertised and what the underlying register numbers are.
My initial motivation was to see if there are any duplicate register
names exposed via the gdbstub while I was reviewing the proposed
register interface for TCG plugins.
Mismatches between the xml and remote-desc are reported for debugging
but do not fail the test.
We also skip the tests for the following arches for now until we can
investigate and fix any issues:
- s390x (fails to read v0l->v15l, not seen in remote-registers)
- ppc64 (fails to read vs0h->vs31h, not seen in remote-registers)

This fix is implemented by having the vCont handler set the value of
`gdbserver_state.c_cpu` if any threads are to be resumed. The specific
CPU picked is arbitrarily from the ones to be resumed, but it should
be okay, as all GDB cares about is that it is a resumed thread.

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.

Currently when we encounter a gdb that is old or not built with
multiarch in mind we fail rather messily. Try and improve the
situation by probing ahead of time and setting
HOST_GDB_SUPPORTS_ARCH=y in the relevant tcg configs. We can then skip
and give a more meaningful message if we don't run the test.

Almost all invocations of run-test have either "$* on $(TARGET_NAME)"
or "$< on $(TARGET_NAME)" as the last argument. So provide a default
test name, while allowing an escape hatch for custom names.
As an additional simplification, remove the need to do shell quoting.

System emulation tests do not run in a hosted environment, since they
do not link with libc. They should only use freestanding headers
(float.h, limits.h, stdarg.h, stddef.h, stdbool.h, stdint.h,
stdalign.h, stdnoreturn.h) and should be compiled with -ffreestanding
in order to use the compiler implementation of those headers
rather than the one in libc.
Some tests are using inttypes.h instead of stdint.h, so fix that.

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 we've truncated a wider read we can detect the condition earlier by
looking at the number of zeros we've read. So we don't trip up on
cases where we have written zeros to the start of the buffer we also
ensure we only start each offset read from the right address.
