    M modules/dialog/dialog.c
    M modules/usrloc/ul_mod.c

  Log Message:
  -----------
  fix bin crash if no listener defined

When using usrloc and dialog replication, if no bin_listen is defined,
OpenSIPS crashes. This fix ensures that if there are any replication
destinations defined, the binary listener exists.

Thanks go to Stas Kobzar for reporting this
Closes #652
