d39a6b7ca9 Instead of mapping the LHS of unused rules to -1, keep the LHS 
valid, but flag the rules as invalid.
* src/gram.h (rule_t): `useful' is a new member.
* src/print.c (print_grammar): Adjust.
* src/derives.c (set_derives): Likewise.
* src/reader.c (packgram, reduce_output): Likewise.
* src/reduce.c (reduce_grammar_tables): Likewise.
* tests/reduce.at (Underivable Rules, Useless Rules): New.

d287d66a69 * src/reduce.c (reduce_output): Formatting changes. 
* src/print.c (print_results, print_grammar): Likewise.
* tests/regression.at (Rule Line Numbers)
(Solved SR Conflicts, Unresolved SR Conflicts): Adjust.

ea451a17d7 * src/reduce.c (nonterminals_reduce): Instead of throwing away 
useless nonterminals, move them at the end of the symbol arrays.
(reduce_output): Adjust.
* tests/reduce.at (Useless Nonterminals): Adjust.

24b1e65f04 * src/reduce.c: Various comment/formatting changes.

(reduce_grammar_tables): here.
(reduce_grammar): Call nonterminals_reduce.

7ad28769d6 (YYSTACK_REALLOC): Remove. 
(YYSTACK_ALLOC): Resurrect this macro, with its old meaning.
(YYSTACK_FREE, YYSTACK_GAP_MAX, YYSTACK_BYTES, YYSTACK_RELOCATE):
New macros.
(union yyalloc): New type.
(__yy_memcpy): Last arg is size_t, not unsigned int, to remove
an arbitrary restriction on hosts where size_t is wider than int.

(yyparse): Don't dump core if alloca or malloc fails; instead, report
a parser stack overflow.  Allocate just one block of memory for all
three stacks, instead of allocating three blocks; this typically is
faster and reduces fragmentation.

Do not limit the number of items in the stack to a value that fits
in 'int', as this is an arbitrary limit on hosts with 64-bit
size_t and 32-bit int.

a9f37dee0c Attaching lineno to buckets is stupid, since only one copy of each
