rename src/ as spot/ and use include <spot/...>

* NEWS: Mention the change. * src/: Rename as ... * spot/: ... this, adjust all headers to include <spot/...> instead of "...", and adjust all Makefile.am to search headers from the top-level directory. * HACKING: Add conventions about #include. * spot/sanity/style.test: Add a few more grep to catch cases that do not follow these conventions. * .gitignore, Makefile.am, README, bench/stutter/Makefile.am, bench/stutter/stutter_invariance_formulas.cc, bench/stutter/stutter_invariance_randomgraph.cc, configure.ac, debian/rules, doc/Doxyfile.in, doc/Makefile.am, doc/org/.dir-locals.el.in, doc/org/g++wrap.in, doc/org/init.el.in, doc/org/tut01.org, doc/org/tut02.org, doc/org/tut03.org, doc/org/tut10.org, doc/org/tut20.org, doc/org/tut21.org, doc/org/tut22.org, doc/org/tut30.org, iface/ltsmin/Makefile.am, iface/ltsmin/kripke.test, iface/ltsmin/ltsmin.cc, iface/ltsmin/ltsmin.hh, iface/ltsmin/modelcheck.cc, wrap/python/Makefile.am, wrap/python/ajax/spotcgi.in, wrap/python/spot_impl.i, wrap/python/tests/ltl2tgba.py, wrap/python/tests/randgen.py, wrap/python/tests/run.in: Adjust.
