fix "input buffer overflow, can't enlarge buffer..."

Browse source 
This occured when parsing the HOA automaton generated by Rabinizer3 for
a very long LTL formula with many nested U.  State labels could easily
be more than 40k characters.

* src/parseaut/scanaut.ll: Fix that.
* src/tests/parseaut.test: New test case.
* NEWS: Mention the fix.

* unabbreviate could easily use forbidden operators.
* "autfilt --is-unambiguous" could fail to detect the nonambiguity
of some automata with empty languages.
* When parsing long tokens (e.g, state labels representing
very large strings) the automaton parser could die with
"input buffer overflow, can't enlarge buffer because scanner uses REJECT"
