[RFA] Delete struct source, struct sourcevector from symtab.h

[David Carlton <carlton@math.stanford.edu>]

symtab.h contains definitions for 'struct source' and 'struct
sourcevector', but nobody ever refers to them.  If you look through
ChangeLog-1999, you see the comment:

	* symtab.h:  Remove struct sourcevector and struct source.  Definately
	not needed.

But, despite that, they haven't actually been removed.  Oops.

Here's a patch; I've compiled and checked, and they really aren't
referred to anywhere.  OK?
