[PATCH - Shapelib] Add API to support SAHooks in shptree
|Reported by:||Even Rouault||Owned by:||warmerdam|
Attached a patch for shapelib that adds new API to access .QIX files through SAHooks instead of STDIO API. Old API is preserved of course.
After this patch is applied, I'll be able to apply the shapefile_full_use_of_vsil.patch to have only VSIF*L use in shapefile driver. Illustrated by the ogr_shape.py.patch that can operate on /vsimem.
