prefixlen2mask() should return a network byte order result as it does imply
by using an in_addr_t as return type. It simplyfies also the usage as in most
cases the mask is used with a struct in_addr address which is also network
byte order. Add prototypes of prefixlen2mask() and mask2prefixlen() to
ospfd.h as it is used or will be used at different places.
