This fixes the warning "the label idx is defined in both types state
and core." by renaming the label to idxS and idxC respectively.

Fixes the syntax of all tests that use R and B as identifiers, which
are keywords now.

Also disables all tests involving nominals as they are currently all
throwing exceptions.

R and B are now keywords and were used as identifiers. Now, r and
b (lowercase) is used instead in the testcases. For consistency, all
other identifiers were lowercased, too.

The CAMLparam0() macro must be invoked at the beginning of a function
that has local variables.

Makes them not only intended alt-free but also parsed to something alt-free

We want to still have the solver for naive unsat propagation

The satsolver is reatined and only updated with new clauses for every
state that is generated out of a core. Once the core becomes Open (as
opposed to expandable), the solver is no longer needed.

This patch makes the solver a `Solver option` and gets it deallocated
once no longer needed and resets the hashtable (makes it empty and zero
size) to save memory. This saves about 60% memory usage on some extreme
cases (e.g. exp_unsat from the CTL Benchmark set)

Instead of some calculation based of finishing on normal Cores really
count proper Open States
