* 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.
