Kristian Nielsen 3c5bfd164f Binlog-in-engine: SAVEPOINT fixes. 
1. Handle RELEASE SAVEPOINT, removing any released savepoint from the list
of savepoints pending in the cache. Also fix a bug in the server layer;
RELEASE SAVEPOINT removes the specified savepoint _and_ any later
savepoints; engines were not informed of the removal of the later ones, if
any.

2. Fix a bug when spilling non-transactional statement data inside of a
transaction using savepoints. The spill of the statement cache must not
spill any savepoints, those apply only to the trx cache.
