Pedro Alves 07b82ea5f9 * target.c: Include "exec.h".
(update_current_target): Don't inherit to_sections or
	to_sections_end.
	(target_get_section_table): New.
	(target_section_by_addr): Fetch the section table from the passed
	in target.
	(memory_xfer_partial): Handle unmapped overlay sections before
	anything else.  Get the overlay mapped address here.  Adjust to
	use section_table_xfer_memory_partial.
	(get_target_memory): Request a TARGET_OBJECT_RAW_MEMORY object
	instead of TARGET_OBJECT_MEMORY.
	(target_resize_to_sections): Delete.
	(remove_target_sections): Adjust to remove target sections from
	`current_target_sections', and use resize_section_table.
	* target.h (struct target_ops) <to_sections, to_sections_end>:
	Remove fields.
	<to_get_section_table>: New method.
	(xfer_memory, print_section_info): Delete declarations.
	(struct target_section_table): New type.
	(target_get_section_table): Declare.
	(target_resize_to_sections): Delete declaration.
	(remove_target_sections): Delete declaration.
	* bfd-target.c (target_bfd_xfer_partial): Get the section table
	from to_data.
	(target_bfd_get_section_table): New.
	(target_bfd_xclose): Adjust.
	(target_bfd_reopen): Store the section table in the to_data field.
	* corelow.c (core_data): New.
	(core_close): Adjust to release core_data and its sections.
	(core_open): Allocate core_data, and build its target sections
	table.
	(deprecated_core_resize_section_table): New.
	(core_files_info): Pass core_data to print_section_info.
	(core_xfer_partial): Adjust to use
	section_table_xfer_memory_partial for TARGET_OBJECT_MEMORY xfers.
	(init_core_ops): Do not install a deprecated_xfer_memory callback
	anymore.
	* solib.c (update_solib_list): Add the shared library sections
	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...
	(section_table_xfer_memory_partial): ... this, replacing the
	current function of that same name.
	(exec_get_section_table): New.
	(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
	deprecated_core_resize_section_table.
	* exec.h (resize_section_table): Declare.
	(section_table_xfer_memory_partial): Add const char * argument.
	(remove_target_sections): Declare here.
	(add_target_sections): Declare.
	(print_section_info): Declare here.
	* gdbcore.h (deprecated_core_resize_section_table): Declare.
