Replace xfullpath calls by gdb_realpath calls.
	* cli/cli-cmds.c (find_and_open_script): Remove xfullpath from the
	function comment.
	* dwarf2read.c (dw2_map_expand_apply): Remove parameter full_path.
	Remove it from the iterate_over_some_symtabs call.
	(dw2_map_symtabs_matching_filename): Remove parameter full_path.
	Remove it from the dw2_map_expand_apply calls, remove a block handling
	it.
	* psymtab.c (partial_map_expand_apply): Remove parameter full_path.
	Remove it from the iterate_over_some_symtabs call.
	(partial_map_symtabs_matching_filename): Remove parameter full_path.
	Remove it from the partial_map_expand_apply calls, remove a block
	handling it.  Drop gdb_realpath call and cleanups from the real_path
	handling.
	* source.c (openp): Drop the comment part about xfullpath.  Replace
	xfullpath calls by gdb_realpath calls.
	(find_and_open_source): Replace xfullpath call by gdb_realpath call.
	* symfile.h (struct quick_symbol_functions): Remove parameter full_path
	from method map_symtabs_matching_filename and its comment.
	* symmisc.c (maintenance_print_msymbols): Replace xfullpath call by
	gdb_realpath call.
	* symtab.c (iterate_over_some_symtabs): Remove parameter full_path,
	remove it also from the function comment, remove a block handling it.
	Drop gdb_realpath call and cleanups from the real_path handling.
	(iterate_over_symtabs): Drop variable full_path and its use.
	* symtab.h (iterate_over_some_symtabs): Remove parameter full_path.
	* utils.c (xfullpath): Remove.
	* utils.h (xfullpath): Remove.
