Bug#898325: getdp: FTBFS against PETSc 3.9

[Drew Parsons]

Source: getdp
Version: 2.11.3+dfsg1-1
Severity: normal

getdp now fails to build against PETSc, from petsc 3.9.

The error message is:
  [ 60%] Building CXX object CMakeFiles/getdp.dir/Kernel/SolvingAnalyse.cpp.o

               MatSolverType
... etc

This happens because of a change in API in PETSc 3.9. 

There is a tentative patch upstream at
https://gitlab.onelab.info/getdp/getdp/commit/8610fc15c426b322bc37f52796e7b3ca65a2d2d3

petsc 3.9 is currently in experimental. This bug will become serious
once we upload it to unstable.
