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.

914120b970 Ensure values are memset to 0 when calling G_VALUE_COLLECT_INIT()
The reason we need to enforce this is that the GTypeValueTable
documentation explicitly states that memory is memset to 0 when the
value_init function is called.

40bf3aa5d2 gobject: Use new G_VALUE_COLLECT_INIT variant
Makes g_object_new_valist 20% to 30% faster (against 2321e5a).

Profiled against the pan newsreader which uses a variant of simple
and complex object creation.

2a78adc5e3 Only add object to list new objects when it has a custom constructor
This works around the need to take a custom mutex twice and add the
object to a GSList of objects that are currently in construction for the
common case. Only when the constructor is overwritten do we use the
previous behavior and allow things like singleton objects.

The only slightly incompatible change is that previously, it was ok to
call g_object_set() on construct-only properties while the object was
initialized. This will now fail. If that behavior is needed, setting a
custom constructor that just chains up will reenable this functionality.

855deaa578 g_object_unref racy condition can lead to crash
Store whether the object has a toggleref before decrementing the
refcount to prevent race condition when two threads simultaneously
try to unref an object with a refcount of 2.

1937765f9f Add fast path for construction with no params
This avoids a bunch of code and makes construction of simple objects
faster.

Object construction performance improvement:
         Non-Threaded   Threaded
Simple:           14%         5%
Complex:        -1.1%      -2.2%

If the class has no properties there could be no notification anyway.
This is an important optimization for construction of simple objects.

        * gobject.c: fix g_object_set() whithin _init() implementations
        not working for construct-only properties.
        (g_object_init): make the object enter a construct_objects list.
        (g_object_newv): remove object from construct_objects after creation.
        (g_object_set_valist):
        (g_object_set_property): allow construct-only properties for
        objects which are in construct_objects.

0642df0ab3 variant of class_peek() which works for static types only.
Thu Nov 27 17:53:52 2003  Tim Janik  <timj@gtk.org>

        * gtype.[hc]:
        (g_type_class_peek_static): variant of class_peek() which works for
        static types only.

        * gobject.c:
        (g_object_do_class_init): make ::notify a run-action signal.
        (g_object_newv): use g_type_class_peek_static() by default to
        speed up common code path (trades two write-locks for one read-lock).
        (g_object_disconnect):
        (g_object_connect): allow signal specification words to be
        seperated by '-'.
        (g_object_set_valist):
        (g_object_new_valist): don't leak values.
        (g_object_get_property): check property for readability.
        (g_object_set_property): check property for writability and to
        not be construct-only.
        (g_object_set_valist): check property to not be construct-only.

Tue Oct 14 17:40:19 2003  Owen Taylor  <otaylor@redhat.com>

        * gparamspecs.[ch]: Add a new GParamSpecOverride type
        that is a pointer to a different paramspec in a parent
        class or interface.

        * gparam.[ch]: Add g_paramspec_get_redirect_target()
        which follows GParamSpecOverride to the real property.
        Make g_param_spec_pool_list() hand redirections,
        properties on interfaces.

        * gobject.[ch] gobjectnotifyqueue.c: Add
        g_object_interface_install_property,
        g_object_interface_find_property,
        g_object_interface_list_properties(). Redirect virtually all
        publically exposed GParamSpec's to the redirect target if
        any. (->constructor is the exception.)
