cdb_init - open a constant database

cdb_init  places  information  about  fd  into  a  struct  cdb  variable c.  fd has to be a seekable file
       previously opened for reading.

       On systems that support mmap, cdb_init will try to map the whole constant database into memory.

       The inverse operation to cdb_init is cdb_free.
