	Add hooks for new syscalls.  Add decoders for *at, inotify*,
	pselect6, ppoll and unshare syscalls.

	* defs.h: Declare print_sigset.
	* desc.c (sys_pselect6): New function.
	* file.c (decode_open, decode_access, decode_mkdir,
	decode_readlink, decode_chmod, decode_utimes, decode_mknod):
	New functions.
	(sys_open, sys_access, sys_mkdir, sys_readlink, sys_chmod,
	sys_utimes, sys_mknod): Use them.
	[LINUX] (fstatatflags, unlinkatflags, inotify_modes): New
	variables.
	[LINUX] (print_dirfd, sys_openat, sys_faccessat,
	sys_newfstatat, sys_mkdirat, sys_linkat, sys_unlinkat,
	sys_symlinkat, sys_readlinkat, sys_renameat, sys_fchownat,
	sys_fchmodat, sys_futimesat, sys_mknodat, sys_inotify_add_watch,
	sys_inotify_rm_watch): New functions.
	* process.c [LINUX] (sys_unshare): New function.
	* signal.c (print_sigset): New function.
	(sys_sigprocmask): Use it.
	* stream.c (decode_poll): New function.
	(sys_poll): Use it.
	[LINUX] (sys_ppoll): New function.
	* linux/syscall.h: Delcare new syscall handlers.
	* linux/syscallent.h: Hook up new syscalls.
	* linux/alpha/syscallent.h: Likewise.
	* linux/hppa/syscallent.h: Likewise.
	* linux/ia64/syscallent.h: Likewise.
	* linux/mips/syscallent.h: Likewise.
	* linux/powerpc/syscallent.h: Likewise.
	* linux/s390/syscallent.h: Likewise.
