c++: minor fixes

Browse Source 
Address compiler warnings such as

    warning: declaration of 'yyla' shadows a member of 'yy::parser::context' [-Wshadow]

* data/skeletons/lalr1.cc (context): Don't use the same names for
variables and members.
Use foo_ for private members, as in parser.
Also, use the + trick in array accesses to please ICC and provide it
with an int.
