This is a simplistic port of the resolver from BIND 4.8.3 to VxWorks 5.1.

NOTE: Unless you use a special version of calloc() that keeps track and
frees memory when a task exits (we do this for Erlang), you will lose a
non-neglible chunk of memory each time a task exits after having used
any resolver function.
