[frankie@debian.org: HDF5 transition]

Dear RMs

it is now time to start with a transition of HDF5 library in unstable,
after months of permanence in experimental. The 1.8.3 is built in 1.6 
compatible mode, so it should not require changes to sources.

They already depend on libhdf5-serial-dev, so a simple rebuild should suffice
for a smooth transition. If you had not concerns about, I would upload in
sid the hdf5 1.8.3 ASAP. Note that upstream moved to a proper SONAME
support, so distributed new libraries will drop debian-specific versioning in their
names, still used in 1.6 series. All that should be transparent to other

Some clarifications: I mean that the 1.6 legacy libraries will be dropped,
but the 1.8 will be used in compatibility mode anyway.


The _default_ profile will be choosen at compile time, which will provide
1.6 as default API, with 1.8 available by explicit call.
