Declarations for functions in source.c are split between source.h and
symtab.h. This commit moves the small number that are in symtab.h
into source.h. There's just one file that needs to add an include of
source.h in order to build.
I've moved the function header comments from source.c to source.h
inline with the recommended GDB style.

declaration in source.h.
