Changes:
2014/09/12 Duane Wessels

    Added 'new-gtlds' filter, which includes only queries for names
    ending with one of the new (2013/2014) generic TLDs.  This may
    be useful to find hosts/servers using internal names which may
    collide with new gTLDs once they become active.  If you use
    short (not fully qualified) names internally you may be uknownlying
    relying on root (or other) name servers to return NXDOMAIN for
    them.  If so, "you're gonna have a bad time."

    Along with this new feature, TLD lists are now hashed in the
    code for faster lookups.

    Added more entries to the table of known query type names (HINFO,
    AFSDB, PX, SSHFP, NSEC3, NSEC3PARAM, TLSA, DLV).

2012/10/15 Duane Wessels

    The 'refused' filter only works on responses, which are not
    processed by default.  Now, if the 'refused' filter is specified,
    dnstop will automatically process responses and ignore queries.

2012/06/11 Duane Wessels

    Added "qtype-any" filter for displaying ANY queries which are
    now fashionable in DNS based attacks.

    Anand Buddhev pointed out that LDFLAGS= is missing from Makefile.in.
    Also updated known_tlds.h.

2011/01/27 Duane Wessels

    Fixed some portability bugs (OpenBSD, gmake 3.82) and other
    minor bugs.

    Added a feature (-n option) to restrict counting to a given
    query name.

2011/01/05 Duane Wessels

    Found a fixed a few problems after spending some quality time
    looking at the code.

    1) Hash table performance was terrible and has been improved.
       The hash table size is now configurable via command line
       option.

    2) Some things were double-counted when both -Q and -R were
       given.

    3) Added cumulative percentage totals to the tables

    4) Added -X option to disable the source+queryname tables, which
       could consume a lot of memory.

    5) Imported "inX_addr" mini-library for storing IPv4/IPv6
       addresses.

    Fixed a bug where if stdout was a TTY but stdin was not a TTY,
    then dnstop would enter a loop on keyboard input and consume
    100% CPU.  Now it checks that stdin is a TTY as well.
