    Add two new symbol domains
    
    This adds two new symbol domain constants, TYPE_DOMAIN and
    FUNCTION_DOMAIN.
    
    Historically, gdb was a C debugger, and the symbol tables continue to
    reflect this.  In particular, symbol domains match the C language,
    with VAR_DOMAIN including variables, functions, and types.
    
    However, other languages have other approaches to namespacing.  And,
    in any case, it is often useful for other parts of gdb to be able to
    distinguish between some domains at lookup time, without resorting to
    examining a symbol's location -- in some situations, this sort of
    filtering happens too late.
    
    Nothing uses these new domains yet, but the idea behind the patch is
    to separate symbols into more domains and then let the
    language-specific parts of gdb implement their semantics in terms of
    these categories.
