BUG#6034 - Error code 124: Wrong medium type.

Browse Source 
Version for 5.0. Committed for merge.
If the result table is one of the select tables in INSERT SELECT,
we must not disable the result tables indexes before selecting.
Now the preparation is split into two prepare methods.
The first detects the situation and defers some preparations
until the second phase.
