Keep objfile original filename

gdb/
2013-09-24  Jan Kratochvil  <jan.kratochvil@redhat.com>

	Pass down original filename for objfile.
	* coffread.c (coff_symfile_read): Update symbol_file_add_separate call.
	* elfread.c (elf_symfile_read): Likewise.
	* jit.c (jit_object_close_impl): Update allocate_objfile call, no
	longer set ORIGINAL_NAME.
	(jit_bfd_try_read_symtab): Update symbol_file_add_from_bfd call.
	* jv-lang.c (get_dynamics_objfile): Update allocate_objfile call.
	* machoread.c (macho_add_oso_symfile): Add parameter name.  Update
	symbol_file_add_from_bfd call.
	(macho_symfile_read_all_oso): Update two macho_add_oso_symfile calls.
	(macho_check_dsym): Add parameter filenamep.  Change function comment.
	Set *filenamep.
	(macho_symfile_read): New variable dsym_filename.  Update
	macho_check_dsym call.  Use it for symbol_file_add_separate.
	* objfiles.c (allocate_objfile): Add parameter name.  New comment for
	it.  Use it for objfile->original_name.
	(objfile_name): Return OBFD's filename, if available.
	* objfiles.h (allocate_objfile): Add new parameter name.
	* solib.c (solib_read_symbols): Update symbol_file_add_from_bfd call.
	* symfile-mem.c (symbol_file_add_from_memory): Update
	symbol_file_add_from_bfd call.
	* symfile.c (read_symbols): Update symbol_file_add_separate call, new
	comment for it.
	(symbol_file_add_with_addrs): New parameter name, add function comment
	for it.  Remove variable name.  Update allocate_objfile call.
	(symbol_file_add_separate): New parameter name, add function comment
	for it.  Update symbol_file_add_with_addrs call.
	(symbol_file_add_from_bfd): New parameter name.  Update
	symbol_file_add_with_addrs call.
	(symbol_file_add): Update symbol_file_add_from_bfd call.
	(reread_symbols): New variable original_name.  Save
	objfile->original_name by it.
	* symfile.h (symbol_file_add_from_bfd, symbol_file_add_separate): Add
	second parameter.
