When g_type_class_get_private is called without calling
g_type_add_class_private first, a g_warning is issued, but
the name of the function to call is wrong:
g_type_class_add_class_private.

This lets you cache type lookup information and then know when
the cache information is out of date. In particular, we want this
in order to be able to cache g_type_from_name() lookups in the Gtk+
theme machinery.

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.

Move the guts of g_type_init() into a ctor and turn g_type_init() itself
into a do-nothing function.
g_type_init_with_debug_flags() now ignores its arguments, but it has
always been possible to achieve the same effect via environment
variables.

Otherwise we crash with a null-ptr deref in g_object_newv and ever there we
should not return null, as we're saying that object creation will not return
null.
It's impossible to check this if the library user is using
g_type_register_static, but in that case their compiler should hopefully
warn about the truncation. This fixes it for G_DEFINE_TYPE and friends,
at least.

All locks are now zero-initialised, so we can drop the G_*_INIT macros
for them.
Adjust various users around GLib accordingly and change the docs.

G_THREADS_ENABLED still exists, but is always defined. It is still
possible to use libglib without threads, but gobject (and everything
above it) is now guaranteed to be using threads (as, in fact, it was
before, since it was accidentally impossible to compile with
--disable-threads).

Some links were broken due to typos, because functionality was removed
in GLib 2.0 or for various other reasons. Fix up as many of them as is
reasonable.
The hash table used exclusively for looking up types by name used to map
quarks => types. But we can easily make it map strings => types, which
avoids the quark lookup. And that in trun avoids taking a lock and
consulting another hash table. So this change should make
g_type_from_name() roughly twice as fast.
This adds static markers and systemtap tapsets for:
* type creation
* object lifetimes (creation, ref, unref, dispose, finalize)
* signal creation and emission
Signal emissions and finalization marker have a corresponding
*_end (or *-end in dtrace) version that is when the corresponding
operation is finished.

This adds the two new functions g_type_add_class_private()
and g_type_class_get_private() and a convenience macro
for the getter G_TYPE_CLASS_GET_PRIVATE().
This way we don't need to keep a custom array that we bsearch on (and
that isn't threadsafe) but can use the gtype.c machinery that is
threadsafe. And fast, too!

g_type_default_interface_peek() and g_type_value_table_peek() don't need
to acquire read locks anymore when they test the refcount instead of
node->data.
The function returns TRUE if the type was previously initialized and can
be easily reused. It returns FALSE and does not take a reference if the
type is not referenced yet.
g_type_class_ref() uses this to avoid taking locks in the common path,
which speeds up object creation a lot - in particular in multithreaded
applications.
