Make state_explicit instances persistent objects.

Browse source 
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh: Merge
state_explicit and tgba_explicit::state.  In the past,
state_explicit was a small object encapsulating a pointer to the
persistent tgba_explicit::state; and we used to clone() and
destroy() a lot of state_explicit instance.  Now state_explicit is
persistent, and clone() and destroy() have no effects.
* src/tgba/tgbareduce.cc: Adjust, since this inherits from
tgbaexplicit and uses the internals of state_explicit.
* src/tgbatest/reductgba.cc: Fix deletion order for automata.
* src/tgba/tgba.hh (last_support_conditions_input_,
last_support_variables_input_): Make these protected, so
they can be zeroed by tgba_explicit.
