* gobject.[ch] gobject.symbols: Add
g_object_add/remove_toggle_ref() functions to get notification
when a reference count is the last remaining reference; this
enables better memory management for language bindings.

* glib/gdataset.[ch] glib/gdatasetprivate.h: Add
g_datalist_set/unset_flags(), g_datalist_get_flags() functions
to squeeze some bits into a GDataSet... this is needed for
efficient implementation of toggle references in GObject.
* tests/gobject/references.c tests/gobject/Makefile.am:
Add a test case for weak and toggle references.
* glib/gfileutils.[ch]: Rename g_file_replace() back
to g_file_set_contents().
* glib/glib.symbols: Update.

<!-- ##### MACRO G_VALUE_COLLECT ##### -->

<para>
|
|
Collects a variable argument value from a va_list. We have to
|
|
implement the varargs collection as a macro, because on some systems
|
|
va_list variables cannot be passed by reference.
|
|
</para>
|
|
|
|
@value: a #GValue return location. @value is supposed to be initialized
|
|
according to the value type to be collected
|
|
@var_args: the va_list variable; it may be evaluated multiple times
|
|
@flags: flags which are passed on to the collect_value() function of
|
|
the #GTypeValueTable of @value.
|
|
@__error: a #gchar** variable that will be modified to hold a g_new()
|
|
allocated error messages if something fails
