* spot/tl/formula.hh (formula::operator bool): Make it explicit. When
compiling in C++20 mode with g++ 10.1, this bool operator was used
instead of the comparison operators while looking up a
std::pair<formula,formula> in a hash map, causing many test suite
failures. This problem does not occur with clang++ 10.0, so it
might just be a bug in g++ 10.1. But having explicit operator bool
is good practice anyway.
* spot/tl/formula.hh: Add variant of formula::is that support 4
arguments.
* spot/tl/simplify.hh, spot/tl/simplify.cc: Add option keep_top_xor
to preserve Xor and Equiv at the top-level.
* spot/twaalgos/translate.cc: Adjust ltl-split to deal with Xor and
Equiv for the -D -G case.
* NEWS: Mention that.
* tests/core/ltl2tgba2.test: Add test case.
* tests/python/simstate.py: Adjust expected result.
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.
This was prompted by reports by Andrew Wells and Yong Li.
* NEWS, doc/tl/tl.tex: Document the changes.
* THANKS: Add Andrew.
* bin/ltlfilt.cc: Match --ltl before --from-ltlf if needed.
* spot/parsetl/parsedecl.hh, spot/parsetl/parsetl.yy,
spot/parsetl/scantl.ll: Parse X[!].
* spot/tl/formula.cc, spot/tl/formula.hh: Declare the new operator.
* spot/tl/ltlf.cc: Adjust to handle op::X and op::strong_X correctly.
* spot/tl/dot.cc, spot/tl/mark.cc, spot/tl/mutation.cc,
spot/tl/print.cc, spot/tl/simplify.cc, spot/tl/snf.cc,

* tests/core/ltlfilt.test, tests/core/sugar.test,
tests/core/utf8.test: More tests.
The first issue was reported by Victor Khomenko.
* spot/tl/formula.cc: Introduce a single-argument
version of sugar_delay().
* spot/parsetl/parsetl.yy: Use it.
* doc/tl/tl.tex, spot/tl/formula.hh: Adjust doc.
* tests/core/ltlfilt.test, tests/core/sugar.test: More tests.
* spot/tl/formula.cc, spot/tl/formula.hh (formula::sugar_delay): New
function to implement this operator as syntactic sugar.
* spot/parsetl/parsetl.yy, spot/parsetl/scantl.ll: Parse it.
* doc/tl/tl.tex: Document the syntactic sugar rules and precedence.
* tests/core/sugar.test: Add tests.
* NEWS: Mention this new feature.
* NEWS, doc/tl/tl.tex, doc/tl/tl.bib: Document these new operators.
* spot/parsetl/parsetl.yy, spot/parsetl/scantl.ll: Parse those.
* spot/tl/formula.cc, spot/tl/formula.hh: Add constructors.
* spot/gen/formulas.cc: Use it.
* tests/core/sugar.test: New file.
* tests/Makefile.am: Add it.
* doc/footer.html: Make the footer XML compatible.
* doc/mainpage.dox: Fix references to modules.
* spot/tl/formula.hh: Introduce a hierarchy module.
* spot/tl/hierarchy.hh: Use it.
Fixes#306.
* spot/tl/formula.hh, python/spot/__init__.py: Implement this
in C++ and Python.
* doc/org/tut03.org: Document (and indirectly test) it.
* NEWS: Mention it.
* spot/tl/formula.hh: Move all throw statements behind
some [[noreturn]] report...() methods...
* spot/tl/formula.cc: ... defined here. This makes the methods
shorter and helps their inlining. Incidentally, this also removes the
uninitialized read that weirdly occurs when _GLIBCXX_DEBUG is on, as
observed with #184, but I do not know why.
For #184.

spot/twaalgos/sccinfo.hh, spot/twaalgos/translate.hh: Replace
assert() by SPOT_ASSERT(), or an exception, or nothing, depending
on the case.
* tests/sanity/style.test: Flag all asserts in headers.
* HACKING: Discuss assertions.
* NEWS: Mention the change.
* src/: Rename as ...
* spot/: ... this, adjust all headers to include <spot/...> instead of
"...", and adjust all Makefile.am to search headers from the top-level
directory.
* HACKING: Add conventions about #include.
* spot/sanity/style.test: Add a few more grep to catch cases
that do not follow these conventions.
