* spot/twa/twagraph.cc: Reset prop_universal() if edges are merged in
a non-deterministic automaton.
* tests/core/det.test: Add test case.
* NEWS: Mention the issue.
Reported by František Blahoudek.
* spot/twaalgos/postproc.cc: Turn "t" into "Inf(0)" for BA.
* tests/core/ltl2tgba.test: Add test case.
* NEWS: Mention the bug.
* spot/misc/tmpfile.cc: Display strerror(errno) plus some suggestions
that depend on the error. Based on a report from Shengping Shaw.
* THANKS: Add reporter.
* tests/core/ltlcross5.test: New file.
* tests/Makefile.am: Add it.
* spot/twaalgos/degen.hh, spot/twaalgos/degen.cc: Implement it.
* tests/python/pdegen.py: New file.
* tests/Makefile.am: Add it.
* NEWS: Mention the new function.
This fixes a complementation bug reported by Juraj Major and Tereza
Šťastná.
* spot/twaalgos/remfin.cc (is_scc_tba_type): Fix the condition for
handling Fin-alone pairs.
* tests/core/complement.test: Add Juraj & Tereza's test case.
* NEWS: Mention it.
This is to workaround differences in minidom's pretty-printing that
occurred between Python 3.7 and 3.8.
* python/spot/jupyter.py (SVG): New class.
* python/spot/__init__.py: Use it.

tests/python/word.ipynb: Adjust.
* spot/twaalgos/remfin.cc (tra_to_tba): Remove the SCC-emptiness
check that was done by creating a temporary automaton. Use the
scc_info::check_scc_emptiness() function instead.
* spot/twaalgos/sccinfo.cc,
spot/twaalgos/sccinfo.hh (scc_info::check_scc_emptiness): Mark
this function as const.
(scc_and_mark_filter): Make sure we only combine with a lower filter
of the same type.
* spot/twaalgos/genem.cc: Remove one stray debugging statement.
* tests/python/genem.py: Remove a duplicate test.

* spot/tl/contain.cc, spot/tl/contain.hh: Use a pimp idiom to hide the
hash tables, use robin_hood hash, and strip common Xs to save some
cache lookups.
* spot/tl/simplify.cc: Adjust to change of #include in contain.hh.
* spot/twa/acc.hh (acc_cond::mark_t): Diagnose mark_t with set numbers
that are too larges.
* tests/python/except.py: Adjust.
* tests/core/acc.cc: Remove most of asserts, as those can be disabled,
and adjust expected exception.

that are too larges.

This corrects a bug that has never been observed yet, has it would
require more than UINT_MAX formulas allocations.
* spot/tl/formula.cc, spot/tl/formula.hh: Bump the formula ID in the
unlikely case a new atomic proposition would receive the same id as a
previous one.
* spot/twaalgos/determinize.cc: Implement various micro
optimizations. Use robin-hood hashing in a few places.
