[ELGIS] gdal-grass draft package

[Volker Froehlich]

Dear list readers,

GDAL is built without a grass driver, because that creates a circular
dependency (GDAL depends on GRASS, GRASS depends on GDAL), that has been
a pain in the past. Therefore you can build the GRASS driver as a
plug-in to GDAL -- breaking the circle.

Viji started packaging this driver quite some time ago, but got busy
then. I took over the work and I think I have something working now.

On 64 bit systems, a modified GDAL is necessary, as it hard-codes the
plug-in directory to /usr/lib/gdalplugins, which is wrong for 64 bit.

gdalinfo and ogrinfo seem to work just fine with this driver, but I'd
like it to get some real-world testing. As you can read from me
comments, there still are some open questions.

If somebody is interested in testing, I'll provide binaries, if not too
complicated or will try to help you doing so.

Greetings,

Volker
