poll-h: Create poll.h on all platforms. * lib/poll.in.h: Use double-inclusion guard. Don't define POLL*, struct pollfd, nfds_t, INFTIM when the system has <poll.h>. * m4/poll_h.m4 (gl_POLL_H): Set HAVE_POLL_H. Invoke gl_CHECK_NEXT_HEADERS. Don't set POLL_H. (gl_REPLACE_POLL_H): Don't set POLL_H. (gl_POLL_H_DEFAULTS): Don't initialize POLL_H. * modules/poll-h (Depends-on): Add include_next. (Makefile.am): Create poll.h unconditionally. Substitute also HAVE_POLL_H, INCLUDE_NEXT, PRAGMA_SYSTEM_HEADER, NEXT_POLL_H.
