* src/bin/randaut.cc, src/bin/man/randaut.x: New files.
* src/bin/Makefile.am, src/bin/man/Makefile.am: Adjust.
* src/tgbaalgos/randomgraph.hh, src/tgbaalgos/randomgraph.cc:
Add an option to output state-based acceptance, and update
the TGBA properties.
* src/tgbatest/randaut.test: New test.
* src/tgbatest/Makefile.am: Add it.
* src/tgbaalgos/randomgraph.cc, src/tgbaalgos/randomgraph.hh:
Add option to generate a complete deterministic automaton.
* src/tgbatest/randtgba.cc: Test it.
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.

* src/tgbatest/explicit2.cc: New file.
* src/tgbatest/Makefile.am: Add it.
This is actually the third time I fix random_graph(). On
2007-02-06 I changed the function not to generated dead states,
but in a way that made it non-deterministic. On 2010-01-20 I made
the function deterministic again, but it started to generate dead
states as a side effect. This time, I'm making sure that dead
states won't come again with a test-case that we should have had
from the beginning.
* src/tgbaalgos/randomgraph.cc (random_graph): Add an extra
indirection array, state_randomizer[], so that we can reorder
states indices after a random selection without actually changing
the value of the indices used by unreachable_states and
nodes_to_process.
* src/tgbatest/randtgba.test: New file.
* src/tgbatest/Makefile.am: Add randtgba.test.
* src/tgbaalgos/randomgraph.cc (random_graph): Revert the part of
the patch from 2007-02-06 which silently replaced the use of state
index by state pointers. Storing states pointer in this map cause
some non-determinism because of the memory layout. It was almost
impossible to reproduce bugs found by tests based on randtgba.
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.
