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.

Flatten the formula ltl::formula hiearchy into a single ltl::vnode that
has an enumerator to distinguish the types of node, and a common
interface to access children, update reference counts, etc.  The
ltl::formula class is now a thin wrapper around an ltl::vnode pointer to
keep track of reference counts automatically.  Visitor are not used
anymore; we now have map() and traversor() methods that are more
concise.

This basically fixes #43, but should be followed by some fine tuning
that should now be localized to the formula.hh and formula.cc files.

Some statistics about this patch.  I started working on it on Sep 9, had
a first compiling version two weeks later on Sep 22, and it then took 5
days to fixes the ~70 distincts bugs that were introduced during the
conversion.  About 13200 lines were modified, and one third of those
were removed.

This actually performs three related changes, but separating them
would be quite inconvenient.

1) rename tostring.hh to print.hh a welcome side-effect is that
I could fix several files that included this file for not reason.

2) de-overload some of the to_string functions, and rename them
as follow:

  to_string -> print_psl, print_sere, str_psl, str_sere
  to_utf8_string -> print_utf8_psl, print_utf8_sere,
                    str_utf8_psl, str_utf8_sere
  to_spin_string -> print_spin_ltl, str_spin_ltl
  to_wring_string -> print_wring_ltl, str_wing_ltl
  to_lbt_string -> print_lbt_ltl, str_lbt_ltl
  to_latex_string -> print_latex_psl, str_latex_psl
  to_sclatex_string -> print_sclatex_psl, str_sclatex_psl

Now it is clearer what these functions do, and their restrictions.

3) all those print_* functions now take the stream to write onto
as their first argument.  This fixes #88.
