* Moves how snapshots are supplied to the Isolate. Previously they were given by Behavior::startup_data() but it was only called once at startup. It makes more sense (and simplifies Behavior) to pass it to the constructor of Isolate. * Adds new libdeno type deno_snapshot instead of overloading deno_buf. * Adds new libdeno method to delete snapshot deno_snapshot_delete(). * Renames deno_get_snapshot() to deno_snapshot_new(). * Makes StartupData hold references to snapshots. This was implicit when it previously held a deno_buf but is made explicit now. Note that include_bytes!() returns a &'static [u8] and we want to avoid copying that.
