Update 0.61 to 0.64
--------------------
0.64    2014/10/17 17:51:07
        [CHANGES]
         * Make specific mention of 'TCP' and 'UDP' around socket examples
           where appropriate
         * Allow construction of an IO::Async::Handle using fileno integers
           directly
         * Provide a better search for 'all open filehandles' via IO::Async::OS
           on Linux (RT97942)
         * Allow IO::Async::Listener to have handle_constructor or handle_class
           as a subclass method (RT97208)
         * Clarify documentation on how to use IO::Async::Process's
           on_exception event (RT98929)

        [BUGFIXES]
         * Ensure that Stream's write Futures are also informed of write errors
           (RT97433)
         * Remember to ->remove_child the individual workers of an
           IO::Async::Function (RT99552)
         * Fix IO::Async::Function synopsis example (RT97713)

0.63    2014/07/11 15:09:08
        [CHANGES]
         * Allow Notifier subclasses to last-ditch handle unrecognised
           ->configure() params
         * Added $notifier->adopt_future
         * Added $notifier->invoke_error and 'on_error' event
         * Ensure that TimeQueue inserts in FIFO order for equal timestamps
         * Kill remaining docs to long-dead IO::Async::Sequencer

        [BUGFIXES]
         * Cygwin needs the SELECT_CONNECT_EVEC OS hint as well
         * Probe for a broken port to perform listen() tests on by using
           ReuseAddr => 1 so it matches what IO::Async will do (RT84051)

0.62    2014/03/27 23:15:25
        [CHANGES]
         * Added IO::Async::Future->{done,fail}_later
         * Allow overriding of debug log file or file descriptor
         * Avoid Future's and_then/or_else methods
         * Allow Channel->recv in async mode to return a Future (RT91180)
         * Ensure that Function ->call Futures cancel correctly
         * Added $routine->kill
         * Kill the 'getaddrinfo' => 'getaddrinfo_array' legacy redirection
         * Allow Loop's resolver to be changed to a different object

        [BUGFIXES]
         * Avoid relying on strong forward references in Future, by creating
           intentional cycles on pending Futures. Workaround for bugfix in
           upcoming Future release.
