Merge from HEAD of the handles-as-file-descriptors work.

2004-08-19  Dick Porter  <dick@ximian.com>

	* handles.c (_wapi_handle_count_signalled_handles): Fix thinko
	introduced with the fd offset stuff: unlock handles properly when
	backing off.  Fixes the monologue hang at exit.

2004-08-18  Dick Porter  <dick@ximian.com>

	* sockets.c:
	* io.c: Check that new fds fit in the table, return error if not

	* daemon.c (_wapi_daemon_main):
	* handles.c (shared_init): Have all processes agree on a size for
	the fd table.

	* daemon.c (process_new):
	* handles.c (_wapi_handle_new_internal): Cope when the space
	reserved for file descriptors is larger than the shared segment
	size.  Fixes the crash reported when running mono under gdb on
	macosx.

	* sockets.c:
	* io.c:
	* handles-private.h (_wapi_handle_fd_offset_to_handle): Improve
	error checking with passed-in file descriptors.

2004-08-11  Dick Porter  <dick@ximian.com>

	* sockets.c:
	* io.c: Returned handle values are the file descriptor the handle
	encapsulates

	* handles.c:
	* handles-private.h:
	* daemon.c: Reserve the range of handles that can have the same
	values as file descriptors.  These won't be used, but the values
	will be used as file, console, pipe or socket handles.  The fd to
	handle mapping is done internally and is invisible to users.
	Fixes bug 61828.

	* wapi-private.h (_WAPI_HANDLE_VERSION): Increment, because we now
	reserve a chunk of handle space.
