Changes in GEOS library

[Francesco P. Lovergine]

Dear maintainer

you are receiving this mail as a mantainer of one or more packages related
to the `geos' library (i.e. having libgeos-dev as a build-dep). 

With next 3.3.1+ version, I'm going to split appropriately the Geos C and C++ 
interfaces as explained in #643658.

Most programs require tipically linking the official stable C interface,
so libgeos-dev from now on will provide *only* the libgeos_c dev stuff and
headers. You will need to build-dep on the libgeos++-dev package if 
your program *explicitly* use the C++ interface, instead.

That will allow me to avoid calling at every new geos release
a bin-NMU batch run for ALL r-builddeps, because in the 90% of cases
new releases hide in the unstable C++ library all details of 
changes. Your program in most cases simply does 
not use the OO interface, as shown in

http://trac.osgeo.org/geos/wiki/Applications

For instance, osm2pgsql is expected to FTBS and should be the
only package strictly depending on the C++ interface, ATM.

PS:

CCing release team for information about next changes.
