Higher order languages with garbage collection can have issues releasing
a binding, as they do not control the last reference being dropped on
the binding, source, or target instances.

The way of getting the default value out of a GParamSpec is to allocate
a GValue, initialise it, then call g_param_spec_set_default() to set the
default value into that GValue.
This is exactly how we handle setting the default value for all of the
construct properties that were not explicitly passed to g_object_new().
Instead of doing the alloc/init/store on all construct properties on
every call to g_object_new(), we can cache those GValues in the private
data of the GParamSpec itself and reuse them.
This patch does not actually make that change to g_object_new() yet, but
it adds the API to GParamSpec so that a future patch to GObject can make
the change.

Add a check to prevent adding an interface to a class that has already
had its class_init done.
This is an incompatible change but it is suspected that there are not
many users of this functionality. Two known exceptions are pygobject
(fixed in bug 686149) and our own testsuite (affected tests have been
temporarily disabled by this patch).
Once we confirm that nobody else is using this functionality we can
remove a rather large amount of code for dealing with this case.

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.
The ability to cross-compile glib got broken after the
merge of the 'signal-performance' branch as the assumption
was made that the generated glib-genmarshal can be executed
on the host (which isn't valid when cross-compiling).
Fixed this by using the just-built glib-genmarshal for normal
compilations and the native (host) glib-genmarshal when doing a
cross-compilation as was also done in several other areas of GLib
Tested for host=x86_64-unknown-linux-gnu, target=x86_64-unknown-linux-gnu
and host=x86_64-unknown-linux-gnu, target=i686-w64-mingw32

Transforming a GValue holding flags from a GFlagsValue set that includes the 0
value (no flag bits set) into a string would loop until exhausting all the
available memory.

The GValueArray type was added in a time, during the Jurassic era or so,
when GArray did not have a representable GType. The GValueArray API has
various issues as well:
- it doesn't match the other GLib array types;
- it is not reference counted;
- the structure is fully exposed on the stack, so it cannot be
extended to add reference counting;
- it cannot be forcibly resized.
The nice thing is that now we have a GArray type that can replace in
full GValueArray, so we can deprecate the latter, and reduce the
complexity in GLib, application code, and bindings.

Some of the GLib tests deliberately provoke warnings (or even fatal
errors) in a forked child. Normally, this is fine, but under valgrind
it's somewhat undesirable. We do want to follow fork(), so we can check
for leaks in child processes that exit gracefully; but we don't want to
be told about "leaks" in processes that are crashing, because there'd
be no point in cleaning those up anyway.

We were previously preventing implementations of an interface from
specifying G_PARAM_CONSTRUCT for a property of that interface if the
interface didn't specify it itself (or was readonly).
This is something that should only interest the implementation, so we
remove this restriction.
This allows 6 new possible override scenarios:
- writable -> writable/construct
- writable -> readwrite/construct
- readwrite -> readwrite/construct
- writable/construct-only -> writable/construct
- writable/construct-only -> readwrite/construct
- readwrite/construct-only -> readwrite/construct
and we update the testcase to reflect this.

Add a testcase to check all possibilities for overriding a property
specified on an interface from an implementation of that interface,
changing the type and flags.

First, some ARM systems are not fast enough to meet the 30 second
deadline in gwakeuptest.c, so increase that to 60.
Second, we have some signed/unsigned woes in the gparam transform tests.
These don't really matter, since it's test code, but they do obscure
real leaks in the library.

And remove the 'joinable' argument from g_thread_new() and
g_thread_new_full().
Change the wording in the docs. Clarify expectations for
(deprecated) g_thread_create().
These were the last users of the dynamic allocation API.
Keep the uses in glib/tests/mutex.c since this is actually meant to test
the API (which has to continue working, even if it is deprecated).

The documentation for G_TYPE_CHAR says:
"The type designated by G_TYPE_CHAR is unconditionally an 8-bit signed
integer."
However the return value for g_value_get_char() was just "char" which
in C has an unspecified signedness; on e.g. x86 it's signed (which
matches the GType), but on e.g. PowerPC or ARM, it's not.
We can't break the old API, so we need to suck it up and add new API.
Port most internal users, but keep some tests of the old API too.

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.
Since we added g_object_notify_by_pspec(), an efficient way to install
and notify properties relies on storing the GParamSpec pointers inside
a static arrays, like we do for signal identifiers.
Instead of multiple calls to g_object_class_install_property(), we
should have a single function to take the static array of GParamSpecs
and iterate it.

The g_object_bind_property_with_closures() function should set a
marshaller if the two GClosures don't have one already. This simplifies
the caller code and avoids duplication.
We need to add a new marshaller to the gmarshal.list matching the
signature of the GBindingTransformFunc function.
Since GSettings got the same functionality and flag in commit ca3b7b75b
GBinding should also have the ability to automatically invert a boolean
value without requiring a custom transformation function.
Since using the function pointer version muddles the memory management
requirements of language bindings, we should implement a GClosure-based
variant on top of g_object_bind_property_full().
