Compilation of each header file alone, as a safety check, was removed
when introducing "#pragma once" because we did not have to check for
possible double inclusion.  However we still need to compile each
header to make sure they are self-contained.

* tests/sanity/includes.test: Compile each header.
* tests/run.in: Export various compiler and directory flags.
* spot/twaalgos/emptiness_stats.hh, spot/misc/mspool.hh,
spot/misc/fixpool.hh: Include <spot/misc/common.hh>.
* spot/misc/common.hh: Include <cassert>.
* NEWS: Mention the fixed headers.

* spot/parseaut/parseaut.yy: Add a diagnostic.
* tests/core/parseaut.test: Test it.
* NEWS: Document it.

* tests/run.in: Here.

* tests/sanity/style.test: Allow parenthesis after 'operator delete'.

* tests/core/randtgba.cc: do not time statistics.

* spot/twa/twagraph.hh (state_acc_sets, state_is_accepting): Do not
check num_sets()==0 since this would imply prop_state_acc().

* spot/graph/graph.hh: Use only const variants of begin()/end(), since
they do not modify the iterator.

* spot/twaalgos/sccinfo.cc: We do not need to care
about 0 states anymore.

... by calling valgrind less often.

* tests/core/reduc.test, tests/core/reducpsl.test: Call
valgrind only on 1 of the 12 calls to randltl, and
2 of the 7 calls to reduc.

* tests/core/readltl.cc: Process many formulas from a
file instead of one arg at a time.
* tests/core/parse.test, tests/core/parseerr.test, tests/core/utf8.test:
Adjust to supply a file as input.

* tests/core/tostring.test: Move all the input formulas into...
* tests/core/tostring.cc: ... the code, and do the loop there.

* NEWS, spot/twa/twa.hh: Document the change.
* spot/twa/twagraph.hh, spot/kripke/kripkegraph.hh:
  Add an exception in get_init_state_number().
  get_init_state() now calls get_init_state_number().
* spot/twa/twagraph.cc, spot/twaalgos/simulation.cc,
  spot/twaalgos/powerset.cc, spot/twaalgos/complete.cc,
  spot/twaalgos/sccfilter.cc: Remove now useless tests.
* spot/twaalgos/hoa.cc: Remove now useless comment.
* spot/twaalgos/minimize.cc: Never return an automaton with no state.

* Makefile.am: Add it.

This fix some lintian issues.

* debian/control: Add dependency.

documented.
* NEWS: Mention the fix.

Fix #198.  Reported by Maximilien Colange.

* spot/twaalgos/strength.cc (is_terminal): Test that no accepting
transition lead to a rejecting SCC.
* tests/core/strength.test: Add test case.
* spot/twaalgos/strength.hh, spot/twa/twa.hh, doc/org/concepts.org:
Adjust documentation.
* NEWS: Mention the fix.

* spot/misc/casts.hh: Add a macro down_pointer_cast.

* spot/misc/common.hh: Change SPOT_DEPRECATED definition.

Because gal2c generates some C++ sources that do not match our coding
convention and should not be checked.

* tests/sanity/80columns.test, tests/sanity/style.test: Do not test
files in tests' work directories.

Fixes #195.

* tests/ltsmin/check.test: Extract the spins and gal checks
and move them to...

* tests/Makefile.am: Adjust.

This fixes c9aabcdd.
