These translator may output guards such as (a) || (b), but with the
changes in Spot 1.1.3 it would only work with ((a) || (b)).
Furthermore when ltlcross would fail to parse a neverclaim containing
such a guard, it would fail to parse all later neverclaims, because
the lexer was not properly reset.
* src/neverparse/neverclaimscan.ll: Scan (a) || (b) as a single
token.
(neverclaimyyopen): Reset the lexer.
* src/tgbatest/neverclaimread.test: Add a test for (a) || (b).

the logic.

function. Also speedup the existing functions by avoiding

* src/tgbaalgos/postproc.cc: Use it for monitors, because we do not
care about acceptance conditions.

only LTL formulas with --stutter-invariant.
* src/ltltest/ltlfilt.test: New file.
* src/ltltest/Makefile.am (TESTS): Add it.
* NEWS: Mention these bug fixes.
Provide a way to output automata with state-based acceptance. Also
print the guards using to_lbt_string() for consistency: as a
consequence, atomic proposition that do not match p[0-9]+ are now
double-quoted.

* src/tgbaalgos/isweakscc.cc, src/tgbaalgos/isweakscc.hh: Do not pass
automata since they are known from the scc. Avoid several dynamic
casts. Try to match the established vocabulary wrt "weak" and
"inherently weak". The old is_weak_scc() that used to enumerate cycles
is therefore renamed to is_inherently_weak_scc(), while the new
is_weak_scc() will should ensure all transitions are fully accepting.
* NEWS: Mention the new interface.
Provides 3 heurisitics to compute the strength of an SCC:
inherent, structural and syntactic
* src/tgbaalgos/isweakscc.cc: implementation
* src/tgbaalgos/isweakscc.hh: definition
The set of rules enabled by favor_even_univ try to "lift" the
subformulae that are both eventual and universal, so they appear
higher in the AST. This is contrary to what we used to do (and still
do when the option is unset), were we try to postpone such subformulae
(by moving them down the AST). It is still a bit experimental.
