	* symfile.h (ADD_PSYMBOL_*):  Add language and objfile parameters.
	  Add code to demangle and cache C++ symbol names.  Use macro form
	  if INLINE_ADD_PSYMBOL is true, otherwise use C function form.

	  lookup_demangled_block_symbol):  Remove prototypes and functions.
	* symtab.c (lookup_symbol):  Remove use of expensive_mangler,

	* symtab.c (completion_list_add_symbol):  Rewrite to use cached
	  C++ demangled symbol names.
	* symtab.h:  Much reformatting of structures and such to add
	  whitespace to make them more readable, and make them more
	  consistent with other gdb structure definitions.
	* symtab.h (general_symbol_info): New struct containing fields
	  common to all symbols.

	  allocated symtab to match what we have been using.
