This massively upgrades the frama-c package to be far more useful, including support for a lot more plugins, including Jessie. Jessie unfortunately requires that its plugin is installed alongside frama-c, so we install why2 (where it lives) along with frama-c now. This increases the size, but makes it much more useful. In the future, it may be possible to split out the build such that why2 is a separate expression and frama-c only installs the plugin, rather than all of why2. However, right now this is fine. Furthermore, why3 is now a dependency - the Jessie plugin can use either, and defaults to Why3 now. Per the design, Frama-C can also go from Why2->Why3 as well. We also make Coq and Alt-Ergo dependencies, so that out-of-the-box users get at least one SMT solver and a prover for support. Signed-off-by: Austin Seipp <aseipp@pobox.com>
