* dwarf2read.c: Update calls to changed and renamed functions, and

	references to moved variables.

	(struct dwarf2_cu): Add first_fn, last_fn, cached_fn,
	language, language_defn, list_in_scope, and ftypes members.
	(cu_first_fn, cu_last_fn, cu_cached_fn, cu_language)
	(cu_language_defn, list_in_scope, ftypes, cu_header_offset)
	(baseaddr): Remove globals.

	(dwarf_attr): Renamed to dwarf2_attr.  Add CU argument.
	(set_cu_language, die_is_declaration, die_specification)
	(determine_prefix, determin_prefix_aux, class_name, namespace_name)
	(dwarf2_linkage_name, dwarf2_name, dwarf2_extension)
	(dwarf2_get_ref_die_offset, dwarf2_fundamental_type)
	(initialize_cu_func_list, add_to_cu_func_list): Add CU argument.

	(dwarf2_build_psymtabs_hard): Add local baseaddr.  Initialize
	cu.list_in_scope.  Don't initialize cu_header_offset.
	(add_partial_symbol): Add local baseaddr.
	(psymtab_to_symtab_1): Add local baseaddr.  Use
	objfile->section_offsets for consistency.  Don't initialize
	cu_header_offset; do initialize cu.header.offset and
	cu.list_in_scope.
	(read_file_scope, read_func_scope, read_lexical_block_scope)
	(dwarf_decode_lines, new_symbol): Add local baseaddr.
