GPX test fails on win32

[warmerdam]

The ogr_gpx.py test script is currently failing on win32 (fwtools build). It seems likely that the ogr_gpx_4 test dataset isn't being closed as expected, so the open fails due to the win32 file io exclusion rules.

C:\warmerda\gdal\autotest\ogr>python ogr_gpx.py
python ogr_gpx.py
  TEST: ogr_gpx_init ... success

  TEST: ogr_gpx_3 ... success
  TEST: ogr_gpx_4 ... fail (blowup)

    Got only 0 features, not the expected 2 features.
  TEST: ogr_gpx_2 ... success

I'm looking if I can see something wrong on Linux first.

This could be reproduced on Linux too, with old-gen python bindings. They require explicit destroy on OGR datasets, whereas NG python bindings don't. Fix commited in r12898
