    A few fixes for OS X.

    1) select()ing on a pcap FD doesn't always work.  Advice from
       tcpdump mailing list archive is to put it into non-blocking
       mode and ignore the select() return value.

    2) Added $(LDFLAGS) to link command line in Makefile to have
       dnstop linked with specific libraries.  LDFLAGS will be
       picked up from the environment.

    3) OS X needs to #include <arpa/nameser_compat.h>

    Adriaan Peeters reported that the list of known TLDs is
    out-of-date.  In particular, the .EU domain is not in the list.

    Mark Foster found a bug with the source+SLD list.  It was being
    updated for 3RD-level domain names as well.  Mark also suggested
    that the '@' key should display the source+SLD screen, just as
    '3' and '#' work for 3RD-level.
