	* symfile-mem.c (do_target_read_memory): New function.
	(symbol_file_add_from_memory): Pass do_target_read_memory to
	bfd_elf_bfd_from_remote_memory.
	* corefile.c (write_memory): Update, make a copy of the read-only
	buffer.
	* target.c (target_read_memory): Update.
	(target_write_memory): Update, make a copy of the read-only
	buffer.
	* gdbcore.h (write_memory): Change buffer type to bfd_byte, make
	const.
	* target.h (target_read_memory, target_write_memory): Change
	buffer type to bfd_byte; for write_memory, make it const.
