Timothy Smith 980ec41fe7 Complete application of InnoDB snapshot innodb-5.1-ss2545.

still in use by another thread.

branches/5.1   issue# 4

Fixed a timing hole where a thread dropping an index can free the
in-memory index struct while another thread is still using
that structure to remove entries from adaptive hash index belonging
to one of the pages that belongs to the index being dropped.

The fix is to have a reference counter in the index struct and to
wait for this counter to drop to zero beforing freeing the struct.
