[Fdo_issues] SDF defect fixes(corrupt indexhandling and get extent fix)

[Badreddine Karoui]

Fixed a couple of issues:

An SDF file with a corrupt index cause the provider to crash when
accessed by a scrollable reader. The provider can detect a corrupt index
and avoid using the index table and sometimes regenerate the index on
update. The scrollable reader was not checking for the corrupt condition
and ended up accessing corrupt data.

 

The second defect is related to the get extent aggregate function where
the bound function is not visiting all the branches of the RTree root
node and returning the wrong extent.

 

The files that changed are:
