style: clarify the use of symbol_lists' locations

Browse Source 
symbol_list features a 'location' and a 'sym_loc' member.  The former
is expected to be set only for symbol_lists that denote a symbol (not
a type name), and the latter should only denote the location of the
symbol/type name.  Yet both are set, and the name "location" is too
unprecise.

* src/symlist.h, src/symlist.c (symbol_list::location): Rename as
rhs_loc for clarity.  Move it to the "section" of data valid only
for rules.
* src/reader.c, src/scan-code.l: Adjust.
