Just dropping tevent-0.9.30 into an existing Samba installation
without recompiling Samba is invalid. Maybe we should document that
better, but Samba makes use of internal tevent structures that we give
no ABI guarantees for. See the comment in tevent_internal.h:

   External users should only ever have to include this header when
   implementing new tevent backends.

Samba is one such user. Eventually this tight link will be removed,
but for the moment this is the case. With tevent-0.9.30 we have broken
the assumptions in tevent_internal.h by adding fields. Samba uses that
structure directly, so it needs to be compiled against the
tevent_internal.h of the tevent version that is later installed.
