	table.

	to the current target sections table.
	* exec.c (current_target_sections_1): New global.
	(current_target_sections): New global.
	(exec_close_1): New function, refactored from exec_close.  Remove
	the exec_bfd's sections from the current target sections table.
	Adjust to not use to_sections.
	(exec_close): Remove all target sections.  Call exec_close_1.
	(exec_file_clear): Use exec_close_1 instead of unpushing the
	target.
	(exec_file_attach): Likewise.  Adjust to not use to_sections.  Add
	exec_bfd's sections to the current target sections table.  Don't
	push the exec_ops target here.
	(resize_section_table): New.
	(add_target_sections): New.
	(remove_target_sections): Moved here.
	(section_table_xfer_memory): Adjust to implement the xfer_partial
	interface, and rename to...

	(exec_xfer_partial): New.
	(xfer_memory): Delete.
	(print_section_info): Replace the target_ops parameter by a
	target_section_table parameter.
	(exec_files_info, set_section_command, exec_set_section_address):
	Adjust to use the current sections table.
	(init_exec_ops): Do not register a deprecated_xfer_memory
	callback.  Register to_xfer_partial and to_get_section_table
	callbacks.
	* infrun.c (handle_inferior_event): Update comments around
	solib_add.
	* rs6000-nat.c (xcoff_relocate_core): Adjust to use
