Small fix to get gnapster under solaris
Purpose Gets gnapster to compile under solaris, u_int32_t problems, use glib instead.
bzero is problematic, only used with arrays and structure that are used once,
so standard initialization to 0 will suffice.
Also autoconf macro to define the CONFIG_DIR based on datadir rather than
prefix, old way wouldn't notice if user does ./configure
--datadir=/SomeStrangePlace, macro is copied to autoconf dir as well as
aclocal.m4 for possible reference.
