test suite fixlet for gdb.trace

This is a minor fix to clean up the last remaining test suite
parallelization issue in gdb.trace.

mi-traceframe-changed.exp refers to objdir.  This patch changes the
code to have the same effect, but avoid using that variable.

	* gdb.trace/mi-traceframe-changed.exp: Don't use objdir.
simple test suite fix in gdb.mi

This is another simple test suite change for the parallelization
project.

This changes mi-basics.exp to avoid the use of subdir and objdir and
instead use standard_output_file.

There are still some uses of objdir, but as noted in a new comment in
the patch, these uses are parallel-safe.

	* gdb.mi/mi-basics.exp: Use standard_output_file.
	(test_dir_specification, test_cwd_specification)
	(test_path_specification): Use testsubdir, not subdir and objdir.
simple test suite fix in gdb.ada

This changes one spot in gdb.ada to use standard_testfile.

	* gdb.ada/info_types.exp: Use standard_testfile.
	* target.h (struct target_section): Delete member bfd.
	All users updated to use the_bfd_section->owner instead.
	* exec.c (add_to_section_table): Assert bfd is expected value.
	Remove initialization of target_section.bfd.
	(remove_target_sections): Update.
	(section_table_available_memory): Update.
	(section_table_xfer_memory_partial): Update.
	(print_section_info): Update.
	(exec_set_section_address): Update.
	* record-full.c (record_full_core_xfer_partial): Update.
	* solib-svr4.c (svr4_relocate_section_addresses): Update.
	* solib-target.c (solib_target_relocate_section_addresses): Update.
	* symfile.c (build_section_addr_info_from_section_table): Update.
	* target.c (memory_xfer_live_readonly_partial): Update.
	(memory_xfer_partial_1): Update.
	* solist.h (target_so_ops.find_and_open_solib): Clarify usage of
	temp_pathname argument.
	* nto-tdep.c (nto_find_and_open_solib): Fix setting of temp_pathname
	when opening the file fails.
