Subject: [PATCH] struct siginfo vs. siginfo_t

gdb/
	* amd64-linux-nat.c (amd64_linux_siginfo_fixup): Use siginfo_t instead
	of struct siginfo.
	* arm-linux-nat.c (arm_linux_stopped_data_address): Likewise.
	* ia64-linux-nat.c (ia64_linux_stopped_data_address): Likewise.
	* linux-nat.c (linux_nat_siginfo_fixup, siginfo_fixup)
	(linux_xfer_siginfo, linux_nat_set_siginfo_fixup)
	(linux_nat_get_siginfo): Likewise.
	* linux-nat.h (struct lwp_info, linux_nat_set_siginfo_fixup)
	(linux_nat_get_siginfo): Likewise.
	* linux-tdep.c (linux_get_siginfo_type): Likewise.
	* ppc-linux-nat.c (ppc_linux_stopped_data_address): Likewise.
	* procfs.c (gdb_siginfo_t): Likewise.

gdbserver/
	* linux-arm-low.c (arm_stopped_by_watchpoint): Use siginfo_t instead of
	struct siginfo.
	* linux-low.c (siginfo_fixup, linux_xfer_siginfo): Likewise.
	* linux-x86-low.c (x86_siginfo_fixup): Likewise.
	* linux-low.h: Include <signal.h>.
	(struct siginfo): Remove forward declaration.
	(struct linux_target_ops) <siginfo_fixup>: Use siginfo_t instead of
	struct siginfo.
