Rolls the current transaction back to a savepoint.
Return value: 0 if success, 1 if there was not a savepoint of the given
name.
NOTE: how do we handle this (unlikely but legal) case:
[transaction] + [update to non-trans table] + [rollback to savepoint] ?
The problem occurs when a savepoint is before the update to the
non-transactional table. Then when there's a rollback to the savepoint, if we
simply truncate the binlog cache, we lose the part of the binlog cache where
the update is. If we want to not lose it, we need to write the SAVEPOINT
command and the ROLLBACK TO SAVEPOINT command to the binlog cache. The latter
is easy: it's just write at the end of the binlog cache, but the former should
be *inserted* to the place where the user called SAVEPOINT. The solution is
that when the user calls SAVEPOINT, we write it to the binlog cache (so no
need to later insert it). As transactions are never intermixed in the binary log
(i.e. they are serialized), we won't have conflicts with savepoint names when
using mysqlbinlog or in the slave SQL thread.
Then when ROLLBACK TO SAVEPOINT is called, if we updated some
non-transactional table, we don't truncate the binlog cache but instead write
ROLLBACK TO SAVEPOINT to it; otherwise we truncate the binlog cache (which
will chop the SAVEPOINT command from the binlog cache, which is good as in
that case there is no need to have it in the binlog).
