Added missing test method commentary.

Updated test fixture classes in src/bin/d2/tests/nc_add_unittests.cc and
nc_trans_unittests.cc to derive from TransactionTest.

  Integrates d2::NameAddTransaction and d2::NameRemoveTransaction into
  d2::D2UpdateMgr.

Added todo to dns_client.cc commentary regarding
trac# 3286 and the behavior isc::dns::Message::fromWire.

Added commentary to d2/tests/nc_test_utils.h::FauxServer
Corrected doxygen errors

Changed DNSClient ctor to require response param be
an empty pointer and clarified related commentary.
Added debug log statement to log transaction start.
Other minor cosmetics.

Conflicts:
	src/lib/dhcp/iface_mgr.cc

The DHCPv4 server is now responsible for setting up a correct unicast
source address for the outgoing packet. The IfaceMgr doesn't replace
the broadcast address with the unicast address anymore.

   Completes initial implmementation of example hooks libary, user_chk.

Removed reponse packet type check from IPv6 packet_snd callout.
Corrected text in user chk doxygen page.

Addressed review comments which were largely minor. Limited use of
extern C linkage to only the callout functions themselves. Added
a dox page describing the library.  Added namespace user_chk.

3207 was created quite some time ago, so master was
merged into it first.

The obsolete usage of AC_OUTPUT was actually causing config.status
to be executed multiple times, which is a big waste of time. Changed
to use the correct AC_CONFIG_FILES and AC_CONFIG_COMMANDS macros
instead.
