Fixes#260. Reported by František Blahoudek.
The simplification F(f)|q = F(f|q), where q designates an event_univ
formula, was not always applied because of a couple of issue: (1) the
mospliter was ignoring event_univ unless favor_event_univ was set, (2)
when processing formulas from res_EventUniv they were not put back
into res_F or res_G to be subject to the F/G rules.
* spot/tl/simplify.cc: Improve handling of the above points.
* tests/core/reduccmp.test: Adjust and add test case.
* tests/core/ltl2tgba2.test, tests/python/atva16-fig2a.ipynb: Adjust.

an alternating automaton.
Fixes#257.

Report from Jeroen Meijer.
* spot/Makefile.am (libspot.pc): Depends on Makefile. Use a
temporary. Declare in CLEANFILES instead of DISTCLEANFILES.
* spot/ltsmin/Makefile.am (libspotltsmin.pc): Likewise.

Fixes#233, although more cleanup would be welcome.
* spot/twaalgos/minimize.cc: Replace the uses of twa methods by
twa_graph methods, and simplify some data structures.
* tests/core/acc_word.test, tests/core/readsave.test,
tests/python/automata.ipynb: Adjust changed output due
to different data structures.
* spot/gen/automata.hh (aut_pattern): Add the dict argument.

This helps with autocompletion in IPython, and it will prevent us from
mixing LTL patterns with automata patterns (once we have more than one
automata generator).

can be called.
For #254.
* doc/org/arch.tex: Include libspotgen and its python bindings,
genaut, and also the buddy bindings.
* doc/org/concepts.org: Adjust the description.
* bin/genaut.cc: Use RANGE instead of N, and document it.
Output the FORMAT documentation, and fix handling of %F and %L.
* tests/core/genaut.test: New file.
* tests/Makefile.am: Add it.
Similarly to genltl that generates LTL formulas for various classes that
appear in the literature, genaut generates automata.
* NEWS: Mention the modification.
* bin/Makefile.am: Build the new binary.
* bin/genaut.cc: The new binary itself.
This library, called libspotgen, gathers functions to generate classes
of automata found in the literature.
Related to #254.
* NEWS, README: Mention the modification.
* Makefile.am, debian/control, debian/libspotgen0.install: Build the new
library in a separate package.
