On Windows and possibly other platforms the '%p' printf modifier does
not prefix printed values with '0x', so do not expect the warning
message to contain the '0x' prefix for the handler pointer value.
This will not catch the case where we fail in libffi and always use 0.
In fact, be a real annoying person and use (1 << 31) as a flags value to
test signedness, too.
Also update the testcase to actually use flags everywhere and ot uint.

This is the sole piece of code in GLib where we make use of the
stack growing direction. And this test proves that we have been
getting the direction wrong all these years...
Basically due to a combination of va_args semantics around
signed/unsigned ints, this test case fails on ppc64. At the moment,
we have as yet to find any real-world consumer with such a large
enumeration value.
Unfortunately, the possible fixes for this are extremely invasive;
we would have to define a new enum API.
Given both of these facts, we believe it makes the most sense at the
current time to simply not test this. If we at a later time determine
there is such a real-world consumer, we can look at doing the
necessary fixes.

Very many testcases, some GLib tools (resource compiler, etc) and
GApplication were calling g_type_init().
Remove those uses, as they are no longer required.

If the closure is invalidated we drop the ref on the signal handler
node, but if the signal is currently being dispatched, the ref could be
held elsewhere.
Flag that we no longer have an outstanding invalidation handler so that
we don't try to unregister ourselves when the other ref drops.
Add a testcase that catches this situation.
In some cases, signal arguments have to be collected, even if there are i
no signal handlers connected (e.g. for GVariant parameters, where collection
consumes a floating variant).
Based on a patch by Christian Persch.
Bug #643624.
