property.

* src/tgba/sba.hh: Delete.
* src/tgba/Makefile.am, wrap/python/spot.i: Adjust.
* src/taalgos/tgba2ta.cc: Do not include sba.hh.
* src/neverparse/neverclaimparse.yy: Set the SBA property on the output.
* src/tgbaalgos/lbtt.cc (lbtt_read_gba): Set the StateBasedAcc property
on output.
* src/tgbaalgos/dotty.cc, src/tgbaalgos/neverclaim.cc: Do not rely on
the sba interface.
* src/dstarparse/dra2ba.cc, src/dstarparse/nra2nba.cc,
src/tgbaalgos/simulation.cc, src/tgbaalgos/sccfilter.cc: Set
tgba_digraph::StateBasedAcc as appropriate.
* src/tgbatest/ltl2tgba.cc: Add extra assert.

This is a huge patch.  tgba_digraph are equiped with some boolean
properties that can be used to indicate whether they represent SBA
(and will carry more informations later).  All algorithms that produce
or use sba_explicit_* automata are changed to use tgba_digraph.
postproc has been rewritten using only tgba_digraph, and this required
changing the return types of many algorithms from tgba* to
tgba_digraph*.

wrap/python/spot.i: Update.

* src/misc/common.hh (SPOT_RETURN): New macro.
* src/tgba/tgbagraph.hh (out, states, transitions): Use it.

The conversion is not complete, because the conversion from SERE to DRA
used for the closure operator is still building a tgba_explicit_formula.

* src/tgbaalgos/ltl2tgba_fm.cc, src/tgbaalgos/ltl2tgba_fm.hh: Return
a tgba_digraph.
* src/priv/acccompl.cc: Simplify.
* src/graph/ngraph.hh: Add a way to iterate over all names.
* src/tgba/tgbagraph.hh (compute_support_conditions): Return something
useful.  It's actually used by the constructor of testing automata.
* src/tgbatest/wdba.test: Adjust to the fact that state are not
labeled by formulas anymore.
* src/bin/ltl2tgba.cc, src/bin/ltl2tgta.cc: Do not try to enable
UTF8 on automata anymore.

* src/tgba/tgbagraph.hh: Store the number of the initial state, not a
pointer to it, because if the state vector is reallocated due to some
later calls to new_state(), this pointer will be invalid.
* src/graphtest/tgbagraph.cc, src/graphtest/tgbagraph.test: Test
for this.

* HACKING: Adjust requirements.  g++4.8 is now OK
for all our targets.

num_transitions() already exist.
