Backward compatibility issues

Due to the 2-digit number '10' in GDAL 1.10, the GDAL_VERSION_NUM macro has been changed.
The new advised way of testing the GDAL version number (for GDAL 1.10 or later) at compilation time is :

ifdef GDAL_COMPUTE_VERSION /* only available in GDAL 1.10 or later */
if GDAL_VERSION_NUM >= GDAL_COMPUTE_VERSION(1,10,0)
///
endif
endif

Testing of previous versions is of course unchanged.

* Add Geometry.GetPoints() (only for Python and Java) (4016)
* Add Geometry.GetEnvelope3D()
* Add Geometry.SimplifyPreserveTopology()
* Extend SWIG Geometry.ExportToJson() to accept a list of options (4108)
* Add (OGR)DataSource.SyncToDisk()
* Add SpatialReference.SetVertCS(), IsSameVertCS(), IsVertical(), SetCompound(), IsCompound()
* Add SpatialReference.SetIGH() (4060)
* RFC 35: Add OGRLayer.DeleteField(), ReorderField(), ReorderFields(), AlterFieldDefn()
* Add gdal.VSIFTruncateL()

CSharp bindings:
* Implement the typemap for utf8_path in C (3766)
* Correcting the signature of OGRDataSource.Open to make the utf8 typemap to work (3766)

Java bindings:
* Turn the gdalJNI, gdalconstJNI and osrJNI into package private classes
* Make Layer.GetExtent() return null when OGR_L_GetExtent() fails.

Perl bindings:
* The "Points" method of Geometry was not accepting its own output in the case of a single point. It accepted only a point as a list. Now it accepts a point both as a list containing one point (a ref to a point as a list) and a point as a list.
* Fixed UTF-8 support in decoding names (datasource, layer, field etc.).
* Assume all GDAL strings are UTF-8, handle all changes in typemaps.
* Additions to Perl bindings due to new developments etc: Layer capabilities, GeometryType method for Layer, improved create, new Export and Set methods for SpatialReference.
* Detect context in a typemap which returns a array, this now returns a list in list context; the change affects at least GetExtent and GetEnvelope methods, which retain backward compatibility though new and/or changed methods: FeatureDefn::Name, FeatureDefn::GeometryIgnored, FeatureDefn::StyleIgnored, Feature::ReferenceGeometry, Feature::SetFrom, FieldDefn::Ignored, Geometry::AsJSON
* Perl typemaps: more correct manipulation of the stack, more cases where a list is returned in a list context, better handling of callback_data Band::COLORINTERPRETATIONS, Band methods Unit, ScaleAndOffset, GetBandNumber, RasterAttributeTable method LinearBinning
* Typemaps for VSIF{Write|Read}L, tests and docs for some VSI* functions.
* Perl bindings: better by name / by index logic, some checks for silent failures, return schema as a hash if wanted, support ->{field} syntax for features, return list attributes as lists or listrefs as wished so that ->{field} works for lists too (API change)

Python bindings:
* Improvements for ogr.Feature field get/set
* Add hack to bring Python 3.2 compatibility
* First argument of VSIFWriteL() should accept buffers for Python3 compat
* Fix reference leak in 'typemap(in) char **dict'
* Add gdal.VSIStatL()
* swig/python/setup.py : fix for virtualenv setups (4285)
* Layer.GetExtent() : add optional parameter can_return_null that can be set to allow returning None when OGR_L_GetExtent() fails
* Make gdal.VSIFSeekL(), gdal.VSIFTellL() and gdal.VSIFTruncateL() use GIntBig instead of long for compat with 32bit platforms
* Add script to build the python extensions with Python 2.7 and a mingw32 cross-compiler under Linux/Unix

Ruby bindings:
* Build SWIG Ruby Bindings against modern Ruby versions (1.8.7 and 1.9.2) (3999)
