Currently, libqtest allows for memread and memwrite, but
does not offer a simple way to zero out regions of memory.
This patch adds a simple function to do so.

It turns out there are test cases that use multiple libqtest instances.
We cannot use a global qtest instance in the SIGABRT handler.

This reverts commit cb201b48.

If an assertion fails during qtest_init() the SIGABRT handler is
invoked.  This is the correct behavior since we need to kill the QEMU
process to avoid leaking it when the test dies.

The global_qtest pointer used by the SIGABRT handler is currently only
assigned after qtest_init() returns.  This results in a segfault if an
assertion failure occurs during qtest_init().

Move global_qtest assignment inside qtest_init().  Not pretty but let's
face it - the signal handler depends on global state.

Older versions of gcc (eg 4.6) can't handle varargs functions declared
inline for anything other than completely trivial uses, and complain:

tests/qom-test.c: In function 'qmp': tests/libqtest.h:359:60: sorry,
unimplemented: function 'qmp' can never be inlined because it uses
variable argument lists

Avoid this problem by putting the functions into libqtest.c instead
of using inline definitions in libqtest.h.

Add a qtest qmp() function that returns the response object.  This
allows test cases to verify the result or to check for error responses.
It also allows waiting for QMP events.

Existing qmp() callers do not expect a response object.  In order to
implement real QMP test cases it will be necessary to inspect the
response object.

Rename qmp() to qmp_discard_response().  Later patches will introduce a
qmp() function that returns the response object and tests that use it.

In order to convert qmp() macro to an inline function, expose a
qtest_qmpv() function, reused by qtest_qmp().

We can't apply GCC_FMT_ATTR() since fdc-test is using zero-length format
strings, which would result in warnings treated as errors.

libqtest.h provides a number of shortcut macros to avoid tests feeding
it the QTestState they operate on. Most of these can easily be turned
into static inline functions, so let's do that for clarity.
This avoids getting off-by-one error messages when passing wrong args.

Some macros had a val argument but documented @value argument. Fix this.

While touching things, enforce gtk-doc markup for return values and for
referencing types.
