* wrap/python/ajax/protocol.txt: New file.
* wrap/python/ajax/Makefile.am (EXTRA_DIST): Add it.

* wrap/python/ajax/ltl2tgba.html: Adjust to use
jQuery 1.6.1 and jQuery-UI 1.8.13.  Remove a useless check
of $("#autoupdate").attr("checked") since this checkbox no longer
exists.
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.8.custom.css:
Replace by ...
* wrap/python/ajax/css/ui-lightness/jquery-ui-1.8.13.custom.css: This.
* wrap/python/ajax/Makefile.am (EXTRA_DIST): Adjust.

* src/misc/intvcmp2.cc (stream_compression_base::run):
Implement a shift-less encoding for the 1-bit and 3-bit cases.
Also declare offsets as size_t, to help 64-bit compilers.

size_t.

* src/misc/intvcmp2.cc (int_array_array_compression): Specify full
type of stream_compression_base<int_array_array_compression> in
constructor to please g++ versions <= 4.3.

* iface/dve2/dve2.cc (dve2_state, dve2_compressed_state): Store
size and count on 16 bits, and hash on 32 bits, to limit memory
wasted.

* iface/dve2/dve2.cc, iface/dve2/dve2.hh, iface/dve2/dve2check.cc:
Add a -Z option and pass it through.

* src/misc/intvcmp2.cc, src/misc/intvcmp2.hh: New files.
* src/misc/Makefile.am: Add them.
* src/tgbatest/intvcmp2.cc: New test.
* src/tgbatest/Makefile.am: Add it.
* src/tgbatest/intvcomp.test: Call it.

* src/misc/intvcomp.cc (stream_compression_base::run): Limit
repeatitions to 40, not 42.
(stream_decompression_base::refill): Refill the end of the stream
with 0.
(stream_decompression_base::look_n_bits): Add assertion.
* src/tgbatest/intvcomp.cc: Add a new test case.

* src/misc/intvcomp.cc, src/misc/intvcomp.cc: Add interfaces to
compress vector<int> to vector<unsigned>.
* src/tgbatest/intvcomp.cc: Test them.
* src/sanity/style.test: Refine check to avoid a spurious report.

* configure.ac: Do not add CXXFLAGS and CFLAGS in ac_configure_args,
it causes problem when using config.cache.  Instead ...
* m4/devel.m4: Add --enable-devel or --disable-devel on
ac_configure_args, now that BuDDy understands that.

* src/misc/intvcomp.hh: Likewise.

* src/misc/intvcomp.hh: Move all code...
* src/misc/intvcomp.cc: ... in this new file.
* src/misc/Makefile.am: Add invcomp.cc

* iface/dve2/dve2.cc: Adjust to use the new mspool allocator,
and get rid of the std::vector used to store compressed states.
* src/misc/intvcomp.hh: Add an "int* -> int*" interface
in addition to the "int* -> vector<unsigned>*" interface.
* src/tgbatest/intvcomp.cc: Test the two interfaces.

* src/misc/mspool.hh: New file.
* src/misc/Makefile.am: Add it.

* iface/dve2/dve2.cc (dve2_compressed_state): New class.
(callback_context): Deal with general state*s, not dve2_state*s.
(transition_callback_compress): New function.
(dve2_kripke): Take a compress option.
(get_init_state, compute_state_condition, succ_iter,
format_state, state_condition): Handle compressed states.
(get_vars, compute_state_condition_aux): New helper methods.
* iface/dve2/dve2.hh (load_dve2): Add a compress option.
* iface/dve2/dve2check.cc: Add a -z option.
* iface/dve2/finite.test, iface/dve2/dve2check.test: Add more
tests.

* src/misc/intvcomp.hh: New file.
* src/misc/Makefile.am: Add it.
* src/tgbatest/intvcomp.cc, src/tgbatest/intvcomp.test: New files.
* src/tgbatest/Makefile.am: Add them.

* wrap/python/tests/setxor.py, wrap/python/tests/bddnqueen.py:
Clean all used bdd variables before calling bdd_done(), so that
bdd_delref() is never called after bdd_done().  In NDEBUG builds,
bdd_delref() does not check whether the BuDDy is running or not,
and calling it after bdd_done() will crash.

during emptiness check or counterexample generation.

a fixed-size memory pool for product_state instances.

instances and their variables.

* src/misc/fixpool.hh: New file.
* src/misc/Makefile.am (misc_HEADERS): Add fixpool.hh.

settings to sub configure.

* src/misc/casts.hh: New file.
* src/misc/Makefile.am: Add it.
* iface/dve2/dve2.cc, iface/gspn/gspn.cc, iface/gspn/ssp.cc,

src/tgbaalgos/ndfs_result.hxx, src/tgbaalgos/reductgba_sim.cc,
src/tgbaalgos/reductgba_sim_del.cc: Use down_cast when
appropriate.

* src/sanity/style.test: Catch some binary operators not
delimited with spaces.
* src/tgbaalgos/bfssteps.cc, src/tgbaalgos/magic.cc,
src/tgbaalgos/reducerun.cc, src/tgbaalgos/se05.cc,
src/tgbaalgos/tau03.cc, src/tgbaalgos/tau03opt.cc: Fix these.

* 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.

* src/tgba/tgbareduc.cc, src/tgba/tgbareduc.hh (format_state):
Remove this useless copy of the tgba_explicit_string::format_state
method.

Client code should always call the destroy() method instead.  (It
was introduced in Spot 0.7.)

* src/tgba/state.hh (state::~state): Make it protected.

The gain is not very impressive.  The runtime of the first example
in iface/dve2/README (also in dve2check.test) is 15% faster.

* src/tgba/tgbaproduct.hh (tgba_succ_iterator_product): Move ...
* src/tgba/tgbaproduct.cc (tgba_succ_iterator_product,
tgba_succ_iterator_product_common): ... in these two classes.
(tgba_succ_iterator_product_kripke): New class to speedup
successor computation on Kripke structures.  We can assume that
all the transitions leaving the same state have the same label.
(tgba_product::tgba_product, tgba_product::succ_iter): Use
tgba_succ_iterator_product_kripke when appropriate.
(tgba_product_init::tgba_product_init): Adjust for the case
where tgba_product did reverse its operands.
