This operator is to ':' what [*i..j] is to ';'.
Part of issue #51.
* doc/tl/tl.tex: Document syntax, semantic, and trivial
simplifications.
* doc/tl/spotltl.sty: Add macros for new operators.
* src/ltlast/bunop.cc, src/ltlast/bunop.hh: Implement it.
* src/ltlast/multop.cc: Add some trivial simplifications.
* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Parse it.
* src/ltltest/equals.test, src/ltltest/latex.test,

Instead, manage all reference counting from ltl::formula.
It ridance of virtual calls to clone() and destroy() easily compensate
the extra test in destroy() to not delete constant nodes.

src/ltlast/multop.cc, src/ltlast/multop.hh, src/ltlast/unop.cc,
src/ltlast/unop.hh: Use std::tuple to replace nested std::pair,
simplify calls to std::map::erase, use auto and std::make_pair with
insert, and simplify the dump() method using a range for.
* src/ltlvisit/simplify.cc: Here.
* doc/tl/tl.tex: Document then.
* src/ltlast/bunop.hh (as_KleenStar): New helper function.
* src/ltltest/reduccmp.test: Add more tests.

without reduce_size_stricly.

* src/ltlast/multop.cc: Implement the trivial rewriting.
* src/ltlast/multop.hh, doc/tl/tl.tex: Document it.

src/ltlvisit/simplify.cc, src/ltlvisit/tostring.cc,
src/tgbaalgos/ltl2tgba_fm.cc: Remove all traces of these two
operators since they are not handled like sugar.
* doc/tl/tl.tex: Adjust documentation to reflect the fact that these
two operators are sugar.
* src/ltlast/bunop.hh: Declare bunop::Goto
* src/ltlast/bunop.cc: Handle it.

the translation.
* src/ltltest/equals.test: Test trivial identities.
* src/tgbatest/ltl2tgba.test: Test two more formulae using [->].
* src/ltlast/bunop.hh: Declare bunop::Equal
* src/ltlast/bunop.cc: Handle it.
* src/ltlparse/ltlparse.yy,
src/ltlparse/ltlscan.ll: Add rules for [=min..max].
* src/tgbaalgos/ltl2tgba_fm.cc: Handle bunop::Equal in
the translation.
* src/ltltest/equals.test: Test trivial identities
for [=min..max].
* src/tgbatest/ltl2tgba.test: Add new formulae to test.
* src/ltlast/bunop.hh, src/ltlast/bunop.cc: New files for
bounded unary operators.

* src/ltlparse/ltlparse.yy, src/ltlparse/ltlscan.ll: Add parse
rules for LTL. This required passing the parse_error list
to the lexer, so it can report scanning errors when it reads
a number that does not fit in an unsigned int.
* src/ltlparse/parsedecl.hh (YY_DECL): Take error_list
as third argument.
* src/ltltest/consterm.test, src/ltltest/tostring.test,

"bunop::Star" instead of "unop::Star".
* src/tgbaalgos/ltl2tgba_fm.cc: Likewise, but also adjust
the code to handle the bounds of the operator.
