6e1a037357 Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF.

75b170b164 Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes 
the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine
has a chance to run.  Since the aiRowEst now might be deleted from freeIndex()
which does not always have a db pointer, make sure the aiRowEst memory is
not held in lookaside.
