Fixes#50.
* src/tgbaalgos/cycles.cc, src/tgbaalgos/cycles.hh: Rewrite using
unsigned instead of state*, and std::vector instead of std::map.
* src/tgbaalgos/isweakscc.cc, src/tgbaalgos/powerset.cc: Adjust.
This helps issue #26 considerably, but I'm not closing it because there
are a few places here and there that can be cleaned up. For instance
build_state_set in minimize.cc should be rewritten.
* src/misc/bitvect.hh (bitvector_array::clear_all): New method.
* src/tgbaalgos/powerset.cc (tgba_powerset): Rewrite it.
* src/tgbaalgos/powerset.hh (power_map): Simplify.
This involves reimplementing some algorithms using tgba_digraph, and
implementing an explicit product that takes two tgba_digraphs and
produces a tgba_digraph.
* src/tgbaalgos/product.cc, src/tgbaalgos/product.hh: New files.
* src/tgbaalgos/Makefile.am: Adjust.

src/tgbatest/randtgba.cc: Update to use scc_info and/or tgba_digraph.
This is a huge patch, that took over a month to complete. The bit sets
are currently restricted to what 'unsigned can store', but it should be
easy to extend it to 'uint64_t' should we need it.
* NEWS: Update.
* src/tgba/acc.hh: New file.
* src/tgbatest/acc.cc, src/tgbatest/acc.test: Test it.
* src/tgba/tgbakvcomplement.cc, src/tgba/tgbakvcomplement.hh,
src/tgba/tgbasgba.cc, src/tgba/tgbasgba.hh: Delete. The KV
complementation is too slow to be used in practice, and I somehow broke
it during the conversion to bitsets. The tgba->sgba conversion was only
used for the KV complementation, and should be better redone on
tgba_digraph_ptr should it be needed again.

Replace tgba_explicit* by the actual type used.
* src/tgbatest/explicit2.cc: New file.
* src/tgbatest/Makefile.am: Add it.
* src/tgbaalgos/powerset.hh (power_map): New structure, allowing
the caller to retrieve the set of original states corresponding to
the set in the deterministic automaton.
(power_set): Adjust prototype to take a power_map instead of the
acc_list.
* src/tgbaalgos/powerset.cc (power_set): Strip all code using
acc_list, and update power_set.
* src/tgbaalgos/minimize.cc (minimize): Rewrite, using an
algorithm similar to the one in the Dax paper to check whether
state of the minimized automaton should be accepting.
* src/tgbaalgos/minimize.cc (minimize): Don't add acceptance
conditions if the final set is empty.
* src/tgbaalgos/powerset.cc (tgba_powerset): Add the initial state
to acc_list if it is accepting. Also do not compute an SCC build
map if we don't have to build acc_list.
from the initial automaton.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
Added class tgba_explicit_number, a tgba_explicit where states are
labelled by integers.
* src/tgbaalgos/powerset.hh, src/tgbaalgos/powerset.cc:
When building the deterministic automaton, keep track of which states
were created from an accepting state in the initial automaton.
The states are added to the new optional parameter (if not 0),
acc_list.
Use tgba_explicit_number instead of tgba_explicit_string to build
the result.
* src/tgbaalgos/scc.cc (spot): Small fix.
Print everything on std::cout.
tgba_explicit instances labelled by other objects than strings.
* src/tgba/tgbaexplicit.cc, src/tgba/tgbaexplicit.hh:
Split tgba_explicit in two levels: tgba_explicit with unlabelled
states, and tgba_explicit_labelled templated by the type of
the label. Define tgba_explicit_string (with the interface
of the former tgba_explicit class) and tgba_explicit_formula
for future use in ltl2tgba.cc.
