[#260, !120] Fixed typo in the User's guide.

[#260, !120] PacketQueueMgr4/6 are no longer singletons

    dhcp::IfaceMgr simply owns instances of the packet queue
    managers, rather than them being singletons.

[#260,!120] Moved thread creation from Receiver ctor to new start function

    dhcp::Receiver - moved creating receiver's thread out of the constructor
    to new Receier::start() method.  This alleviates issues with thread worker
    functions referring to Receiver members before Receiver fully exists.

[#260,!120] Removed Mutexing from IfaceMgr, PacketQueue must now be thread-safe

    Removed Mutexing from IfaceMgr, added it to default kea packet queue
    implementations.  PacketQueue derivations are required to be thread-safe,
    thus leaving upto implementers to choose how.

[#260,!120] Extracted IfaceMgr thread bits into new class, isc::dhcp::Receiver

src/lib/dhcp/iface_mgr.*
    Extracted the thread, watch sockets, mutex, and error message members
    from IfaceMgr and wrapped them in a new class, isc:dhcp::Receiver.

    IfaceMgr::add_fd(int fd, int& maxfd, fd_set* sockets) - new
    convenience method for adding descriptors to fd_set(s)

src/lib/dhcp/tests/iface_mgr_unittest.cc
    class ReceiverTest - new test fixture
    TEST_F(ReceiverTest, receiverClassBasics)  - new unit test

[#260,!120] Addressed most of review comments

    Addressed all comments except parsing regen and
    refactor of watch sockets in IfaceMgr.  Doing those
    separately.

[#260,!120] Replaced hard-coded default queue type names

[#260,!120] Added Congestion Handling chapter to admin guide

Added a new chapter on Congestion Handling rather than independent
sections for kea-dhcp4 and 6.
