make a big difference.
Especially with should write !(p0) and not !p0, because p0 is
usually #define'd by the user and he may have forgotten to quote
the value of the macro. This issue was discovered by Kristin
Yvonne Rozier and diagnosed by Gerard Holzmann.

* src/tgbaalgos/neverclaim.hh (never_claim_reachable): Take
a tgba as input.
* src/tgbaalgos/neverclaim.cc (never_claim_bfs): Call
state_is_accepting() only if this tgba turns out to be
a tgba_sba_proxy. Otherwise check the acceptance of one
outgoing transition as we do in dotty_bfs since 2011-03-05.
* src/tgbatest/ltl2tgba.cc: Do not redegeneralize before
calling never_claim_reachable() if we know the automaton is
degeneralized already.
* src/tgbatest/ltl2tgba.test: Add a test case.
Right now, destroy() just executes "delete this". But in a later
version, we will rewrite tgba_explicit so that it does not
allocate new states (and the destroy() method for explicit state
will do nothing).
* src/tgba/state.hh (state::destroy): New method, to replace
state::~state() in the future.
(shared_state_deleter): New function.
