* select.h: New file split from fhandler.h.

(select_record::select_record): Define do-nothing constructor for "new" to
avoid gratuitous zeroing.
(select_info): New base class.
(select_pipe_info): New class with methods for dealing with pipes.
(select_socket_info): New class with methods for dealing with sockets.
(select_serial_info): Dummy class for serial.
(select_mailslot_info): Dummy class for mailslots.
(select_stuff): Define device_specific_* as actual classes rather than void *.
* dtable.h (dtable::select_read): Accommodate return value change to 'bool' and
argument change to "select_stuff".
(dtable::select_write): Ditto.
(dtable::select_except): Ditto.
* dtable.cc (dtable::select_read): Accommodate return value change to 'bool'
and argument change to "select_stuff".
(dtable::select_write): Ditto.
(dtable::select_except): Ditto.
* fhandler.h: Excise select-related classes.
(fhandler_*::select_read): Change argument to select_stuff.
(fhandler_*::select_write): Ditto.
(fhandler_*::select_except): Ditto.
* select.cc (UNIX_FD_ZERO): Use memset rather than bzero.
(select_stuff::test_and_set): Change return type to bool.  Allocate
select_record on entry and let fhandler_*::select_* operate on the start.next
field of select_stuff.
(pipeinf): Delete.
(select_pipe_info::select_pipe_info): New constructor.  Allocates event for
controlling pipe waits.
(select_pipe_info::~select_pipe_info): New destructor.  Destroy event.  Stop
thread.
(select_pipe_info::add_watch_handle): New function.
(thread_pipe): Wait for the hEvent part of any overlapped pipes before peeking.
(start_thread_pipe): Don't allocate device_specific_pipe stuff here.  Assume
that it has been allocated earlier.
(pipe_cleanup): Rely on select_pipe_info destructor to clean up pipe
paraphenalia.
(fhandler_*::select_*): Derive select_record from new select_stuff argument.
(fhandler_pipe::select_*): Ditto.  Allocate pipe-specific field if not already
allocated.
(serialinf): Delete.
(thread_serial): serialinf -> select_serial_info.
(fhandler_base::ready_for_read): Rewrite to accommodate change in argument to
fhandler_*::select_*.
(socketinf): Delete.
(thread_socket): socketinf -> select_socket_info.
(mailslotinf): Delete.
(thread_mailslot): mailslotinf -> select_mailslot_info.
