f02ec2f2de Optimize single-handler va_marshaller case
When there is only one closure handling a signal emission and
it doesn't have a bunch of complicated features enabled we
can short circuit the va_args collection into GValues and call the
callback via the va_marshaller directly.

a3e91088ce Use builtin marshallers and va_marshallers if possible
If the signal argumment types matches a built in standard
marshaller we use the va_marshaller for that, and also the
normal marshaller if NULL was specified (as its faster than
the generic one).

7964cda8e6 Add g_signal_set_va_marshaller
This lets you set a va_marshaller on your signal which will be
propagated to all closures for the signal. Also, automatically
uses the generica va_marshaller if you specify a NULL c_marshaller.

d5fbbe400a Add GRealClosure and move meta_marshallers there
This means we're not abusing the notifiers for meta_marshallres,
and we're able to later cleanly add other fields to GClosure.

We still have to leave the ABI intact for the GClosure->meta_marshal
bit, as old G_CLOSURE_N_NOTIFIERS macro instances still accesses it.
However, we always set it to zero to keep those macros working.

fb95c20c96 Add G_SIGNAL_DEPRECATED
Similar to G_PARAM_DEPRECATED. It will warn only for users of the
signals, so a signal can still be emited without warning, for
compatibility reasons.

Apparently, there is no way user flags could have been used before,
so that shouldn't break anyone.

b74e2a720a Stop using glib-genmarshal at build time
To help cross compilation, don't use glib-genmarshal in our
build.  This is easy now that we have g_cclosure_marshal_generic().

In gobject/, add gmarshal.[ch] to git (making the existing entry
points stubs).

In gio/, simply switch to using g_cclosure_marshal_generic().

8e41be13ef Add dtrace and systemtap support for gobject
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.

20d4f6da73 Bug 541208 – Functions to easily install and use signals without class
2008-07-04  Michael Natterer  <mitch@imendio.com>

	Bug 541208 – Functions to easily install and use signals without
	class struct slot

	* gobject.symbols
	* gsignal.[ch] (g_signal_new_class_handler): the same as
	_gtk_binding_signal_new(), to install signals with a callback
	instead of a class struct slot as class closure.

	The next two functions are C convenience and much easier to use
	than the generic overriding and chaining APIs which are intended
	primarily for language bindings:

	(g_signal_override_class_handler): to override a signal with a
	callback instead of a class struct slot.

	(g_signal_chain_from_overridden_handler): to chain up from a
	signal without class struct slot. The API is similar to
	g_signal_emit().

Tue Nov  1 16:24:20 2005  Tim Janik  <timj@imendio.com>

        * glib/gmem.[hc]: prepared deprecation of GMemChunk and GAllocator.
        added g_slice_*() API to allocate and cache small bits of memory.
        an actuall allocator implementation for g_slice_*() is still pending.

        * glib/gthread.[hc]: changes from a patch by Matthias Clasen.
        changed GRealThread list to use in-structure *next; fields instead
        of GSList, in order for thread iteration to not depenend on g_slice_*()
        indirectly.
        _g_thread_mem_private_get():
        _g_thread_mem_private_set(): added accessors for private memory,
        needed because the ordinary GPrivate implementation relies on GArray
        and GSList and therefore indirectly on working g_slice_*() allocations.

        * glib/gthread.[hc]:
        g_thread_foreach(): new public API function to loop over all existing threads.

        * glib/gdataset.c:
        * glib/gstring.c:

        removed GAllocator and free list usages and accompanying locks.
        use g_slice_*() API to allocate and cache small bits of memory.

        * glib/ghook.h: removed GMemChunk field from public API.

        * glib/gslist.h:
        * glib/glist.h: deprecate allocator API, provide _free1() for consistency.

        * glib/gnode.h: deprecate allocator API.

        * glib/gmain.c: reordered GPollRec fields so g_slice_free_chain() can
        be used for poll rec lists.

        * glib/grel.c: removed mem chunk usage, and allocated tuples via g_slice_*().
        g_relation_destroy(): free all tuples from the all_tuples hash table,
        this effectively maintains the life time track keeping of tuples.
        g_relation_delete_tuple(): free tuples which are removed from the
        all_tuples hash table. this fixes a temporary leak that was present
        in the memchunk code until the destruction of the relation.
