sat_minimize: improve logs and document Python bindings

Browse source 
* spot/priv/satcommon.cc, spot/priv/satcommon.hh: Make it possible to
set the log file without setting the environment variable.  Adjust
print_log to take the input state and print it as a new column.
* spot/twaalgos/dtbasat.cc, spot/twaalgos/dtwasat.cc: Adjust all
calls to print_log.  Fix log output for incremental approaches.
Prefer purge_unreachable_states() over stats_reachable().  Do
not call scc_filter() on colored automata.
* spot/twaalgos/dtwasat.hh: Document the new "log" option.
* NEWS: Mention the changes.
* tests/python/satmin.ipynb: New file.
* tests/Makefile.am: Add it.
* doc/org/satmin.org, doc/org/tut.org: Link to it.
* doc/org/satmin.org, bin/man/spot-x.x: Adjust description
of CSV files.
* bench/dtgbasat/gen.py, bench/dtgbasat/tabl.pl,
bench/dtgbasat/tabl1.pl, bench/dtgbasat/tabl2.pl,
bench/dtgbasat/tabl3.pl, bench/dtgbasat/tabl4.pl: Adjust for
the new column.
* spot/misc/satsolver.cc, spot/misc/satsolver.hh (stats): Make it
const.
* python/spot/__init__.py (sat_minimize): Add display_log and
return_log options.
* tests/python/ipnbdoctest.py: Adjust to not compare SAT-minimization
logs as they contain timings.

If set to a filename, the SAT-based minimization routines will append
statistics about each iteration to the named file. Each line lists
the following comma-separated values: requested number of states,
number of reachable states in the output, number of edges in the
output, number of transitions in the output, number of variables in
the SAT problem, number of clauses in the SAT problem, user time for
encoding the SAT problem, system time for encoding the SAT problem,
user time for solving the SAT problem, system time for solving the SAT
problem.
the following comma-separated values: input number of states, target
number of states, number of reachable states in the output, number of
edges in the output, number of transitions in the output, number of
variables in the SAT problem, number of clauses in the SAT problem,
user time for encoding the SAT problem, system time for encoding the
SAT problem, user time for solving the SAT problem, system time for
solving the SAT problem, automaton produced at this step in HOA
format.
