Use a QDoubleSpinBox instead of a QLineEdit for the snapping
 tolerance, make the treeview columns adjust better to the size of the
 contents
OGR provider: deal with wkbUnknown25D (wkbUnknown | wkb25DBit)

This geometry type doesn't exist admitedly in the OGRwkbGeometryType
enumeration but a few OGR drivers can expose layers of this type.
Those layers should be dealt exactly like wkbUnknown layers, i.e.
QGIS should analyze the content to see if there are points, lines,
polygons and create derived layers.

Also report the geometry type of wkbGeometryCollection25D layers in
the U.I.
Use GEOS reentrant API (_r functions) and update requirement to GEOS >= 3.1.0

Currently QGIS uses the 'classic' GEOS API that uses a global context.
This can conflict with libraries that would also use the global context
and potentially finalize it whereas QGIS will still use it later.

See https://groups.google.com/forum/#!topic/spatialite-users/9YSU6c5AVQ4 for
such an example of such a recent issue with Spatialite.

The _r API is available since GEOS 3.1.0, which is already an ancient GEOS
version. For example, old-old-stable Ubuntu (Lucid 10.04) and Debian (squeeze)
ship with GEOS 3.1.0 or later.

Such move has also been done in GDAL 1.11
(http://lists.osgeo.org/pipermail/gdal-dev/2013-August/036877.html)
and MapServer 7.0 (https://github.com/mapserver/mapserver/issues/4733)

There's no easy way unfortunately to check at compile time that you don't
use the non _r API. I have patched my geos_c.h header to #ifdef that API (quite
painfull to do..). A postprocessing check can be done however with :

objdump -T output/lib/*.so | grep -v Base | grep GEOS | grep -v _r | grep -v "_ZN" | grep -v GEOSversion

It should return nothing.
