* src/ta/tgtaexplicit.cc, src/ta/tgtaexplicit.hh: Use a ta_explicit
attribute instead of inheriting from it.
(get_ta): New method.
* src/taalgos/minimize.cc, src/taalgos/minimize.hh,
src/taalgos/tgba2ta.cc, src/tgbatest/ltl2tgba.cc: Adjust usage.
* wrap/python/spot.i (as_ta): Remove, now that we have get_ta.
* wrap/python/ajax/spot.in: Use get_ta instead of as_ta.
* src/ta/taexplicit.hh, src/ta/taexplicit.cc, src/taalgos/minimize.cc,
src/taalgos/tgba2ta.cc, src/tgbatest/ltl2tgba.cc: correct the code style
in order to respect the sanity rules
* src/ta/tgta.hh, src/ta/tgta.cc, src/ta/tgtaexplicit.hh,
src/ta/tgtaexplicit.hh, src/ta/tgtaproduct.hh, src/ta/tgtaproduct.cc,
src/taalgos/minimize.cc, src/taalgos/minimize.hh,
src/taalgos/emptinessta.hh, src/taalgos/emptinessta.hh,
src/taalgos/emptinessta.cc, src/taalgos/tgba2ta.hh,
src/taalgos/tgba2ta.cc: rename tgbta to tgta
in this source files.
* src/ta/tgbtaexplicit.hh, src/ta/tgbtaproduct.hh, src/ta/tgbta.cc,
src/ta/tgbtaproduct.cc, src/ta/tgbta.hh, src/ta/tgbtaexplicit.cc:
Rename as...
* src/ta/taexplicit.cc, src/ta/taexplicit.hh, src/ta/taproduct.cc,
src/ta/taproduct.hh, src/ta/tgtaexplicit.cc: ... these.
* src/taalgos/sba2ta.hh, src/taalgos/sba2ta.cc: deleted because
the implementation of all the transformations beteween TGBA and
the different forms of TA are new implemented in src/taalgos/tgba2ta.hh
and src/taalgos/tgba2ta.cc.
* src/tgbatest/ltl2tgba.cc: rename the options of commands that build
the different forms of TA.
* src/ta/ta.hh: BUG Fix
* src/ta/Makefile.am, src/tgbatest/ltl2ta.test: impacts of this renaming
* src/ta/taexplicit.cc, src/ta/taexplicit.hh: Bug fix TGTA
* src/taalgos/minimize.cc,src/taalgos/minimize.hh: TGTA minimization
* src/taalgos/tgba2ta.cc: add a TGTA minimization command (uses -Rm)
* src/taalgos/minimize.cc, src/taalgos/minimize.hh
(minimize_tgbta): New function.
* src/taalgos/tgba2ta.cc: Set livelock-accepting flag of TGTA states
to false so they can be merged with other states.
* src/ta/taexplicit.cc (hash): Use id.
* src/ta/taexplicit.hh: Cosmetics.
* src/ta/ta.cc, src/ta/ta.hh, src/ta/taexplicit.cc,

src/taalgos/minimize.hh, src/taalgos/tgba2ta.cc, src/taalgos/tgba2ta.hh,
src/tgbatest/ltl2tgba.cc: changes introduced to add a new form of TA
called GTA (Generalized Testing Automata). GTA is a TA with acceptance-
conditions added on transitions.
* src/ta/ta.cc, src/ta/ta.hh, src/ta/taexplicit.cc,
src/ta/taexplicit.hh, src/ta/taproduct.cc,src/ta/taproduct.hh,

src/taalgos/reachiter.cc, src/taalgos/sba2ta.cc, src/taalgos/sba2ta.hh,
src/tgbatest/ltl2ta.test, src/tgbatest/ltl2tgba.cc: Impacts of the
implementation of a new variant of TA, called STA, which involve a
Single-pass emptiness check. The new options (-in and -lv) added to
build the new variants of TA allow to add two artificial states:
1- an initial artificial state to have an unique initial state (-in)
2- a livelock artificial state which has no successors in order to
obtain the new form of TA which requires only a Single-pass emptiness-
check: STA (-lv).
* src/ta/taproduct.hh, src/ta/taproduct.cc: improvement of TA Product
* src/ltltest/randltl.cc: improvement of WFair Formulas generation
* src/taalgos/minimize.cc: improvement of TA minimization
* src/taalgos/minimize.hh, src/taalgos/minimize.cc: implements a
minimization of TA by merging bisimular states.
* src/taalgos/statessetbuilder.hh, src/taalgos/statessetbuilder.cc:
returns the set of reachable states of a TA (used in minimize.cc).
* src/taalgos/Makefile.am: add them.
* src/tgbatest/ltl2tgba.cc: add commands to test TA minimization
