parsetl: change the interface to return a parsed_formula

Browse source 
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.

* The interface for all functions parsing formulas (LTL, PSL, SERE,

for parsing automata. These function now return a parsed_formula
object that includes both a formula and a list of syntax errors.

desire (stored as the =spot::parsed_formula::f= attribute), the

parsing. Those diagnostics are stored in the
=spot::parsed_formula::errors= attribute, but they can conveniently be
printed by calling the =spot::parsed::format_errors()= method: this
method returns true if and only if a diagnostic was output, so this is
usually used to abort the program with an error status as above.
If =pel= is non empty, =format_parse_errors()= will display the errors
messages and return true. In the above code, we have decided to
