Make core files the process_stratum.
	* corefile.c (core_target): New variable.
	(core_file_command): Remove variable t, use core_target.
	* corelow.c (core_ops): Make it static.
	(init_core_ops): Change to process_stratum.  Initialize CORE_TARGET.
	* defs.h (make_cleanup_unpush_target): New prototype.
	* gdbarch.h: Regenerate.
	* gdbarch.sh (core_pid_to_str): Remove core_stratum from its comment.

	Make core files the process_stratum.
	* gdb.base/corefile.exp (run: load core again)
	(run: sanity check we see the core file, run: with core)
	(run: core file is cleared, attach: load core again)
