MINOR: spoe: Remove SPOE details from the appctx structure

Now, as for peers, we use an opaque pointer to store information related to the
SPOE filter in appctx structure. These information are now stored in a dedicated
structure (spoe_appctx) and allocated, using a pool, when the applet is created.

This removes the dependency between applets and the SPOE filter and avoids to
eventually inflate the appctx structure.
