* dummy-frame.c (dummy_frame): Replace regcache member with

	caller_state.
	(dummy_frame_push): Replace caller_regcache arg with caller_state.
	All callers updated.
	(remove_dummy_frame,pop_dummy_frame,lookup_dummy_frame): New fns.
	(dummy_frame_pop): Rewrite.  Verify requested frame is in the
	dummy frame stack.  Restore program state.
	(cleanup_dummy_frames): Rewrite.
	(dummy_frame_sniffer): Update.  Make static.
	* dummy-frame.h (regcache,frame_info): Delete forward decls.
	(inferior_thread_state): New forward decl.
	(dummy_frame_push): Update prototype.
	* frame.c (frame_pop): dummy_frame_pop now does all the work for
	DUMMY_FRAMEs.
	* infcall.c (breakpoint_auto_delete_contents): Delete.
	(get_function_name,run_inferior_call): New fns.
	(call_function_by_hand): Simplify by moving some code to
	get_function_name, run_inferior_call.  Inferior function call wrapped
	in TRY_CATCH so there's less need for cleanups and all exits from
	proceed are handled similarily.  Detect program exit.
	Detect program stopping in a different thread.
	Make error messages more consistent.
	* inferior.h (inferior_thread_state): Declare (opaque type).
	(save_inferior_thread_state,restore_inferior_thread_state,
	make_cleanup_restore_inferior_thread_state,
	discard_inferior_thread_state, get_inferior_thread_state_regcache):
	Declare.
	(save_inferior_status): Update prototype.
	* infrun.c: (normal_stop): When stopped for the completion of an
	inferior function call, verify the expected stack frame kind.
	(inferior_thread_state): New struct.
	(save_inferior_thread_state,restore_inferior_thread_state,
	do_restore_inferior_thread_state_cleanup,
	make_cleanup_restore_inferior_thread_state,
	discard_inferior_thread_state,
	get_inferior_thread_state_regcache): New functions.
	(inferior_status): Move stop_signal, stop_pc, registers to
	inferior_thread_state.  Remove restore_stack_info.
	(save_inferior_status): Remove arg restore_stack_info.
	All callers updated.  Remove saving of state now saved by
	save_inferior_thread_state.
	(restore_inferior_status): Remove restoration of state now done by
	restore_inferior_thread_state.
	(discard_inferior_status): Remove freeing of registers, now done by
	discard_inferior_thread_state.

	* gdb.base/break.exp: Update expected gdb output.
	* gdb.base/sepdebug.exp: Ditto.
	* gdb.mi/mi-syn-frame.exp: Ditto.
	* gdb.mi/mi2-syn-frame.exp: Ditto.

	* gdb.base/call-signal-resume.exp: New file.
	* gdb.base/call-signals.c: New file.
	* gdb.base/unwindonsignal.exp: New file.
	* gdb.base/unwindonsignal.c: New file.
	* gdb.threads/interrupted-hand-call.exp: New file.
	* gdb.threads/interrupted-hand-call.c: New file.
	* gdb.threads/thread-unwindonsignal.exp: New file.
