This actually performs three related changes, but separating them
would be quite inconvenient.

1) rename tostring.hh to print.hh a welcome side-effect is that
I could fix several files that included this file for not reason.

2) de-overload some of the to_string functions, and rename them
as follow:

  to_string -> print_psl, print_sere, str_psl, str_sere
  to_utf8_string -> print_utf8_psl, print_utf8_sere,
                    str_utf8_psl, str_utf8_sere
  to_spin_string -> print_spin_ltl, str_spin_ltl
  to_wring_string -> print_wring_ltl, str_wing_ltl
  to_lbt_string -> print_lbt_ltl, str_lbt_ltl
  to_latex_string -> print_latex_psl, str_latex_psl
  to_sclatex_string -> print_sclatex_psl, str_sclatex_psl

Now it is clearer what these functions do, and their restrictions.

3) all those print_* functions now take the stream to write onto
as their first argument.  This fixes #88.

* src/ltlvisit/tostring.cc, src/ltlvisit/tostring.hh: Rename into...
* src/ltlvisit/print.cc, src/ltlvisit/print.hh: ... those, and make

The difficulty is not the example, but setting up org-mode to allow
Python and C++ example that use the local libraries, not those
installed system-wide.

* doc/org/.dir-locals.el: Rename as...
* doc/org/.dir-locals.el.in: ... this, so we can easily define
PYTHONPATH and other environment variables.
* doc/org/init.el.in: Enable C++, and make sure but Python
and C++ use the local libraries.
* doc/org/g++wrap.in, doc/org/tut01.org: New files.
* doc/Makefile.am, configure.ac: Adjust.
* wrap/python/spot.py (to_str): Take a parenth argument.

* src/twa/acc.hh (acc_word): This is a 32-bit structure, so
we can use short for both size and op.

* src/bin/common_trans.cc: Skip leading directories, and
do not require that the prefix is followed by space of 0.
* src/tests/ltldo.test: Add a test.
* doc/org/ltlcross.org: Update.

* src/misc/random.hh (barand): Use round() before casting.
* doc/org/oaut.org: Recompute example.
* src/tests/randaut.test, wrap/python/tests/randaut.ipynb: Adjust.

This is particularly important for src/tests/satmin.test, where ltl2tgba
might be killed while writing a huge temporary file used for SAT-based
minimization.  Before this patch, the temporary files would remain in
src/tests/satmin.dir/, easily overflowing the 100GB limit of the docker
containers we use on the build farm.

* src/bin/common_setup.cc: Catch termination signals for all tools,
even those that do not yet clear temporary files.
* configure.ac: Check for sigaction.

This way -S means --state-based-acc like with other tools
producing automata.   This fixes #82.

* src/bin/randaut.cc: Rename -S as -Q, rename --state-acc as
--state-based-acc (with --sbacc as a synonym), and declare -S as the
short version of --state-based-acc.

otherwise they are uninitialized after a vector resize.

* src/bin/randaut.cc: Replace the --acc-type and --acc-sets

an acceptance formula, or an acceptance name parametred by ranges.
Also accept a range for the number of atomic propositions.
