Suggested by Nikos Gorogiannis.

* src/tgba/tgbatba.hh (tgba_tba_proxy::create_state): New method.
(tgba_tba_proxy::uniq_map_): New attribute.
* src/tgba/tgbatba.cc (state_tba_proxy): Use the default
copy constructor.  Empty the destructor.  Implement an empty
destroy() method.  Use addresses for comparison.  Make clone()
a no-op.
(tgba_tba_proxy): Allocate and deallocate the unicity table.
Implement create_sates().
(tgba_tba_proxy, tgba_sba_proxy, tgba_tba_proxy_succ_iterator):
Adjust state construction to call create_state().

* src/tgba/tgbasafracomplement.cc (safra_tree:succ_create): Do not
lookup *i twice, and do not copy it->second.
(safra_tree::normalize_siblings): Do not lookup *node_it before
insertion.

fix a g++ warning.

* configure.ac: Add a --disable-python option tied to
a USE_PYTHON conditional.
* README: Document the option.
* wrap/Makefile.am: Use the conditional.

* wrap/python/ajax/css/ltl2tgba.css: Fix position of the "Send"
button with WebKit.  The folding arrow icon had a vertical border
that overlapped with the next line.

argument to utime().

* src/tgbaalgos/minimize.cc (minimize_wdba): Fix the Löding
algorithm to use colors.  The previous implementation was an
incorrect approximation.
* src/tgbatest/wdba2.test: New file showing two equivalent
formulas that were minimized in automata with different sizes.
* src/tgbatest/Makefile.am: Add it.

* src/kripketest/defs.in (run2): Remove this function.  It was
incorrectly trying to run valgrind even when valgrind is not
installed.
* src/kripketest/kripke.test: Simplify and use run().

* m4/stl.m4 (AC_HEADER_TR1_UNORDERED_MAP): Add some code so
we don't pick a broken tr1::unordered_map.

* src/tgbaalgos/minimize.cc (minimize_dfa): Fix detection of the
last iteration.  An extra iteration case could be missed in case
where a split generates only singletons, and yet predecessor
classes need to be refined.

* src/ltlvisit/length.cc: Fix computation for ltl::multop
operator. "a&b&c" was reported with length 3, ignoring the
"&" operators, because of a typo.
* src/ltlvisit/length.hh: Fix description to correctly
reflect this change intended since 2010-01-22.
* src/ltltest/length.test, src/ltltest/length.cc: New files.
* src/ltltest/Makefile.am: Add them.

* configure.ac, NEWS: Bump version to 0.8.1.

Make sure $(top_builddir)/src is included.

There is no point in degeneralizing an automaton if it can be WDBA
minimized.  Doing so will only augment the number of states and
slow down the powerset construction used by the WDBA minimization.

* src/tgbatest/babiak.test: New file.  It includes 5 formulae
which Tomáš Babiak reported Spot 0.7.1 would take over one hour to
translate if degeneralization and WDBA minimization were both
requested.
* src/tgbatest/Makefile.am (TESTS): Add it.
* src/tgbatest/ltl2tgba.cc: Do WDBA minimization before
degeneralization.  The above formulae are now all translated in a
few seconds.

The previous setup failed with clang++ 3.0.

* m4/stl.m4: New file.
* configure.ac: Call AC_HEADER_UNORDERED_MAP,
AC_HEADER_TR1_UNORDERED_MAP, and AC_HEADER_EXT_HASH_MAP.
* src/misc/hash.hh: Include _config.h, and used the
SPOT_HAVE_UNORDERED_MAP, SPOT_HAVE_TR1_UNORDERED_MAP,
or SPOT_HAVE_EXT_HASH_MAP defines to decide which
file to include.

* wrap/python/ajax/spot.in: Do not print an error
when attempting to create an existing directory.
Reported by Étienne Renault.

* src/kripketest/Makefile.am (LDADD): Remove a broken dependency.
Reported by Yann Thierry-Mieg.
* src/sanity/style.test: Make sure it does not appear again.

* wrap/python/cgi-bin: Remove this directory.
* wrap/python/Makefile.am (SUBDIRS): Remove it.
* configure.ac, README, wrap/python/ajax/README: Likewise.

* wrap/python/ajax/ltl2tgba.html: Remove `.'
from the list of acceptable symbols for AND.

* NEWS, configure.ac: Bump version to 0.8.

* doc/Doxyfile.in: Do not generate LaTeX output.
* doc/Makefile.am: Do not build spotref.pdf.
* NEWS, README: Adjust.

* src/kripke/kripkeexplicit.hh: Reindent, and fix
some comments.

* src/misc/bddalloc.cc (bdd_allocator::initialize): Call
bdd_setmaxincrease(500000), because the default is 50000,
which cause garbage collection to occur too often.

* src/tgbaalgos/neverclaim.cc, src/tgbaalgos/dotty.cc,
src/tgbaalgos/save.cc: Prefer '\n' over std::endl to speedup I/O.
* src/ltltest/genltl.cc (syntax): Use '\n' too, although it won't
make a big difference.

Also offers two ways to output Kripke structures.

* src/kripketest/parse_print_test.cc, src/kripke/kripkeexplicit.cc
: Simplify includes.
* src/kripke/kripkeprint.hh (kripke_save_reachable,
kripke_save_reachable_renumbered): New declarations.
(KripkePrinter): Move and rename...
* src/kripke/kripkeprint.cc (kripke_printer): ... here.
(kripke_printer_renumbered): New class.
(kripke_save_reachable, kripke_save_reachable_renumbered): New
function.
* src/tgbatest/ltl2tgba.cc: Add an option to read Kripke
structures.
* iface/dve2/dve2check.cc: Use kripke_save_reachable_renumbered.
* iface/dve2/defs.in (run2): Remove.
* iface/dve2/kripke.test: Adjust tests.
