        * glib/gslice.c: honour g_mem_gc_friendly settings when freeing
        slices, make sure g_mem_gc_friendly is properly initialized.

        * gmem.[hc]: ensure g_mem_gc_friendly is initialized from G_DEBUG upon
        the first allocation. applied some branching optimizations.

        * docs/macros.txt: reflected --enable-gc-friendly change and
        described ENABLE_GC_FRIENDLY_DEFAULT as well as G_DEBUG=gc-friendly.

        * configure.in: changed --enable-gc-friendly=yes to define
        ENABLE_GC_FRIENDLY_DEFAULT.

        * glib/garray.c: changed ENABLE_GC_FRIENDLY macro #ifdef-s to
        if (G_UNLIKELY (g_mem_gc_friendly)).

        * glib/gtree.c:
        * glib/ghash.c: removed ENABLE_GC_FRIENDLY code which is now taken
        care of by g_slice_free1().

        * tests/slice-test.c: fixed leaks, reported by Kjartan Maraas.
