CUDA: CUBLAS initialization now lazy (at first vector creation).

Unconditional initialization of CUBLAS in PetscInitialize() is very costly for a high number of MPI ranks.
With this commit CUBLAS is only initialized if an actual GPU vector is used.
Also, global barriers are now removed and instead the local GPU driver deals with concurrent initializations.

Update to MPI-2.0 versions of attribute interfaces

Some of these interfaces were removed in MPI-3. This compiles cleanly
with Open MPI 3.0 and is clean according to the style checks.
