QueryTCP is a benchmarking tool for DNS/TCP.
Ported to Linux OS.

Function for reallocating event array implemented.
Some additional cleanup (closing the epoll file descriptor, etc.).
Function for destroying socket entry implemented.
sm_destroy() finished.
Modified Server module accordingly.

Function for creating new socket and associated event added
  (function for reallocating the event array missing).
Functions still lack some synchronisation.
Changes to other functions in order to make them work with
  multiple sockets.

Initial work to change the Socket Manager's API.

Created subdirectories of src/ for better organisation of the
  files.
Modified Makefile accordingly.

This version is quite stable.
Tested with dnsperf, average qps: 56718.
  Not bad, but worse than the first version - should look into
  that and maintain average qps over 60k.

Fixed search for appropriate zone - added function for comparing
  domain names in wire format (dnss_dname_wire_match()) and
  function for finding the zone: zdb_find_zone_for_name().
Fixed inserting and searching names in the Zone data structure.

Server structure (cute_server; should be renamed) created,
  together with basic functions: create(), destroy(), start().
Added create() and destroy() functions for Name Server module.

Module Zone Parser:
  One API function + test implementation of zone parsing (uses
  the test file format).
Minor changes to dns-simple library API (would need further
  changes).

Proper change of the Makefile + some fixes of it.

Name Server is used for answering queries relayed by the Socket
  Manager (Network) module.
The ns_nameserver structure is rather simple now, but will be
  expanded in the future.
Changed some API parameters to const. Should consider the const-
  -ness of parameters more thoroughly.

Lightweight module holding only an array of pointers to RRs and
  with basic operations: create, destroy, add, find and
  destructor for using in the overlying data structure.

Implemented functions
  zdb_create()
  zdb_create_zone()
  zdb_find_zone()
  zdb_remove_zone()
  zdb_insert_name()
  zdb_find_name()
  zdb_destroy()
Removed the useless zds_node structure.
Added some other functions for working with dnss_dname_wire:
  copy, compare, destroy.

Zone database - Now dummy module, no functions implemented yet.
  Later will group all zone data structures, and provide high-
  level API for the other server modules.

Zone data structure - Only wrapper around hash table functions.
  Should provide transparent API for Zone database, disregarding
  the underlying data structure.

Zone node - data structure to hold all information associated with
  a domain name.
  Consider renaming this structure later.
  Used in Zone data structure and through its zds_node structure
  in the rest of the server modules.
  The use of zds_node structure needs revision, maybe useless.

New (now dummy) types for domain name (dnss_dname) and wire format
  of the domain name (dnss_dname_wire). Both typedef'ed to char *.
Convenience methods to get string from dname and to get length of
  a dname. Will be changed later, when the types change.

Minor changes (comment style changed).

Removed sm_start() and thread information from socket-manager.
sm_listen() made public, passed to dispatcher in start_server().
Fixes in dispatcher.

Print routines moved to from common.[ch] to print.[ch].
Added module Dispatcher - just a draft, no tests done yet.

An actual (working) development version should be always in this
  branch.
For subtasks, new branches will be created. For now all the old
  files are here, although this is actually a subtask. Later,
  we will remove all the old code from this branch and move it to
  some other branch.
The master branch should be used for working or stable versions.

Added .gitignore file.
Created basic directory structure for the project and changed
  Makefile accordingly.
Added QtCreator project files (CuteDNS.*).
