* ldmisc.h (demangle): Declare.

* ldmisc.c: Include "libiberty.h".  Include demangle.h with "",
 	not <>.
	(demangle): Make non-static.  Remove remove_underscore paramter.
	Always return an allocated string.
	(vfinfo): Free result of demangle.  Add case 'G'.  Use %T to print
	functionname, rather than calling demangle.  Print a colon between
	the BFD(section+offset) and the line number.
	* ldmain.c (add_archive_element): Improve format of archive
	information in map file.
	(constructor_callback): Don't print anything to the map file.
	* ldlang.c (lang_one_common): Improve format of common symbol
	information in map file.
	* ldctor.c (ldctor_build_sets): If producing a map file, print set
	information.
	* ldwrite.c (print_symbol_table): Print a newline before the
	header in the map file.
	* Makefile.in: Rebuild dependencies.
