        * birnet/birnetthread.hh: made read_barrier() and write_barrier() a NOP
        on systems that don't need barriers. provided full_barrier().

        * birnetthread.cc: fixed a bad bug in atomic_int_set() and
        atomic_pointer_set() which caused atomic values to temporarily be 0.

        * birnet/birnetcdefs.h: provide memory barrier implementations based on atomic ops.

        * birnet/Makefile.am: define BIRNET_MEMORY_BARRIER_NEEDED in birnetconfig.h.

        * configure.inc: provide BIRNET_MEMORY_BARRIER_NEEDED=[01] based on
        glib's G_ATOMIC_OP_MEMORY_BARRIER_NEEDED.
