Bug 192797: improved the implementation of PR_Poll for Win32.  Increase FD_SETSIZE from the default 64 to 1024.  Make PR_Poll fail with PR_INVALID_ARGUMENT_ERROR if we try to add more than FD_SETSIZE fd's to a fd_set.  Do not pass an empty fd_set to select, and do not call select if all three fd_sets are empty.
