Fix segfaults in vlc and other applications that try to unload libgobject at runtime (bug #405173, thanks to Cédric D. for finding a good solution). Drop old ebuilds.

-Subject: Revert "g_file_set_contents(): don't fsync on ext3/4"
-
-We didn't actually do any real-world testing of this, and
-unsurprisingly it turns out to break in at least one widely-used
-configuration (Fedora 19 x86_64, ext4 on LVM).
-
-This reverts commit 9d0c17b50102267a5029b58b1f44efbad82d8f03.

+Subject: [PATCH] gobject: try to link with -Wl,-z,nodelete
+
+Since the type system does not support reloading its data and assumes
+that libgobject remains loaded for the lifetime of the process, we
+should link libgobject with a flag indicating that it can't be unloaded.
