res_init() sets RES_NOCHECKNAME, but the resolver code knows nothing
about that flag. It is only being checked in the leaf implementing
functions:  getaddrinfo(3), gethostbyname(3), getnetbyname(3).
gethostbyname(3) respected the flag and allowed names with bad
characters to be resolved (remember all this is client-side), but
the other two did not respect the flag and failed names containing
_'s for example.
