49701457c2 Now that states have a complete set of members, the linked list of 
reductions is useless: just fill directly the state's reductions
member.
* src/state.h (struct reductions): Remove member `number' and
`next'.
* src/LR0.c (first_reduction, last_reduction): Remove.
(save_reductions): Don't link the new reductions, store them in
this_state.
* src/lalr.c (set_state_table): No need to attach reductions to
states, it's already done.
* src/output.c (output_actions): No longer free the shifts, then
the reductions, then the states: free all the states and their
members.

f693ad146e One structure for states is enough, even though theoretically 
there are LR(0) states and LALR(1) states.
* src/lalr.h (state_t): Remove.
(state_table): Be state_t **, not state_t *.
* src/state.h (core, CORE_ALLOC): Rename as...
(state_t, STATE_ALLOC): this.
Add the LALR(1) members: shifts, reductions, errs.
* src/LR0.c (state_table): Rename as...
(state_hash): this, to avoid name clashes with the global
`state_table'.
* src/print_graph.c, src/LR0.c, src/LR0.h, src/conflicts.c
* src/lalr.c, src/lalr.h, src/output.c, src/print.c: Adjust.

d954473dee Pessimize the code to simplify it: from now on, all the states 
have a valid SHIFTS, which NSHIFTS is possibly 0.
* src/LR0.c (shifts_new): Be global and move to..
* src/state.c, src/state.h: here.
* src/conflicts, src/lalr.c, src/output.c, src/print.c,
* src/print_graph: Adjust.

9839bbe557 * src/state.h (SHIFT_DISABLE, SHIFT_IS_DISABLED): New. 
* src/conflicts.c: Use it.
Restore a few missing `if (!SHIFT_IS_DISABLED)' which were
incorrectly ``simplified''.

b608206eca * src/state.h (SHIFT_SYMBOL): New. 
* src/conflicts.c: Use it to deobfuscate.

aa2aab3c16 * src/state.h (SHIFT_IS_ERROR, SHIFT_IS_GOTO, SHIFT_IS_SHIFT): New. 
* src/lalr.c: Use them.

f59c437a25 * src/state.h (CORE_ALLOC, SHIFTS_ALLOC, ERRS_ALLOC) 
(REDUCTIONS_ALLOC):  New.
* src/LR0.c, src/conflicts.c: Use them to de-obfuscate memory
allocation.

b2ca4022ea * src/state.h (nstates, final_state, first_state, first_shift) 
(first_reduction): Move their exportation from here...
* src/LR0.h: to here.
Adjust dependencies.
* src/getargs.c (statisticsflag): New variable.
Add support for `--statistics'.
Adjust dependencies.
Remove a lot of now useless `extern' statements in most files.

a70083a3ed * src/reader.h: New file. 
Propagate its use instead of tedious list of `extern' and
prototypes.
* src/reader.c: Formatting changes, topological sort,
s/register//.
