(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.
