More cancellation handling fixups.
	* sysdeps/unix/sysv/linux/not-cancel.h: Add waitpid_not_cancel.
	* sysdeps/generic/not-cancel.h: Likewise.
	* catgets/open_catalog.c: Use not-cancelable syscalls.
	* time/Makefile (CFLAGS-getdate.c): Add -fexceptions.
	* sysdeps/unix/sysv/linux/llseek.c: Must not be cancelable.
	* sysdeps/unix/syscalls.list: Don't mark lseek as cancelable.
	* dlfcn/dlfcn.h: Mark dlopen with __THROW again.
	* io/fcntl.h: Don't mark posix_fallocate with __THROW.
	* libio/fileops.c: Use not-cancelable syscalls for fclose.
	* libio/iopopen.c: Use no-cancelable syscalls.
	* libio/stdio.h: Mark popen and pclose with __THROW again.
	* misc/Makefile (CFLAGS-syslog.c): Add -fexceptions.
	* misc/syslog.c: Fix locking and cancellation cleanup handling.
	* posix/unistd.h: Mark ttyname and ttyname_r again with __THROW.

	* sysdeps/generic/unwind.inc: New file.  Copied from gcc.
	* sysdeps/generic/unwind-dw2.c: Update from gcc version.  Remove
	#ifs since we now need all the code compiled.
