thunk: add thunk_dispatch_keep() non-freeing variant

In scenarios where a thunk instance must be dispatched multiple
times, the automatic free is a problem.

This commit moves the free out of the dispatch implementations
and into the thunk_dispatch() wrapper.  So the behavior of
thunk_dispatch() is unchanged.

The new thunk_dispatch_keep() is a plain ->dispatch().  This does
implicitly turn 'thunk_t *' being a free() able allocation into
part of the API, which may be a problem later.  But who cares,
this is a .h for vendoring, not a .so w/ABI guarantees.
