* src/twaalgos/ltl2tgba_fm.hh, src/twaalgos/ltl2tgba_fm.cc: Implement
generation of unambiguous automata.
* src/tests/ltl2tgba.cc: Add option -fu to test it.
* src/bin/common_post.cc: Adjust the group of options so we can easily
add more from ltl2tgba.cc.
* src/bin/ltl2tgba.cc: Add support for -U and --unambigous.
* src/twaalgos/translate.cc, src/twaalgos/translate.hh: Add support
for Unambiguous.

bin/ltl2tgba and tgbatest/ltl2tgba.
* NEWS: Mention the change.

* src/ltlvisit/mutation.cc: Do not bindly rewrite e[]->f and
e<>->f as e, since e is not a valid PSL formula.  Use !{e}
and {e} instead.  Also fix a memory leak in the handling of
bunops, discovered while testing the previous change.
* src/tests/ltlgrind.test: Add a test case.

* doc/org/ioltl.org: Add an example with xargs -0.

and test stutter invariance.
* src/twaalgos/stutter.cc, src/twaalgos/stutter.hh
(check_stutter_invariance): New function.

This addresses the easy part of #79.

* src/twaalgos/postproc.cc: If the input is already BA and we want a BA
as output, do not try the transition-based simulation only to
degeneralize the result.

* src/taalgos/dotty.cc: Ignore 'e'.
* wrap/python/spot.py (setup): Do not force circular states.  The
default should be fine.

Fixes #77.  g++ 5.1 warns about auto_ptr.

* src/twaalgos/ltl2tgba_fm.cc: replace auto_ptr by unique_ptr.

For some reason, we used to install the library (causing the warning
from Lintian while building the Debian packages) and not the binary.
Let's not install any of these: the user interface is not nice enough.

* iface/ltsmin/Makefile.am: Do not install libspotltsmin.la.

* debian/control (libspot-dev): Do not depend on an exact version of
spot.
(spot-doc): depend on libjs-mathjax.
* debian/rules: Patch doc/userdoc/ to use the local version of MathJax.
