Alexandre Duret-Lutz 22f442f758 parsetl: change the interface to return a parsed_formula
This gets the interface of all the functions parsing formula in line
with the interface of the automaton parser: both return a "parsed_*"
object (parsed_formula or parsed_automaton) that contains the said
object and its list of errors.  Doing so avoid having to declare the
parse_error_list in advance.

* spot/tl/parse.hh, spot/parsetl/parsetl.yy: Do the change.
* spot/parsetl/fmterror.cc: Adjust the error printer.
* NEWS: Document it.
