Please add support for PETSc 3.1

[Johannes Ring]

Hi,

PETSc 3.1 was released earlier this year (end of March) but it does not yet work with DOLFIN. It would be nice to add support for this version of PETSc. Here is the error message on the buildbot (linux64-exp):

mpic++ -o dolfin/la/PETScLUSolver.os -c -Wall -pipe -ansi -BOOST_UBLAS_NDEBUG -DDEBUG -g -O2 -Werror -DHAS_MPI=1 -DMPICH_IGNORE_CXX_SEEK -DPACKAGE_VERSION=\"0.9.7\" -DHAS_LAPACK=1 -DHAS_TRILINOS=1 -DHAS_ZLIB=1 -DHAS_UMFPACK=1 -DHAS_PETSC=1 -DHAS_CHOLMOD=1 -DHAS_CGAL=1 -DHAS_SCOTCH=1 -DHAS_PARMETIS=1 -fno-strict-aliasing -frounding-math -fPIC -I. -I/work/jhbuildbot/fenics/include -I/usr/include -I/usr/include -I/usr/include -I/usr/include/libxml2 -I/work/jhbuildbot/local/include -I/usr/include -I/work/jhbuildbot/local/include/trilinos -I/usr/include -I/usr/include/suitesparse -I/work/jhbuildbot/src/petsc-3.1-p2/local/linux-gnu-cxx-debug/include -I/work/jhbuildbot/src/petsc-3.1-p2/local/include -I/work/jhbuildbot/local/include -I/work/jhbuildbot/local/lib -I/usr/include/suitesparse -I/work/jhbuildbot/src/CGAL-3.5.1/Build/local/include -I/work/jhbuildbot/src/scotch_5.1/local/include -I/usr/include dolfin/la/PETScLUSolver.cpp

dolfin/la/PETScLUSolver.cpp:176: error: ‘PCFactorSetShiftNonzero’ was not declared in this scope

PETSc 3.1 was also recently introduced in Debian replacing the PETSc 3.0 packages. DOLFIN in Debian is therefore currently broken: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=583419

I fixed this a while ago, but it must have become 'unfixed'. I'll take
another look.

I haven't been using PETSc 3.1 since SLEPc hasn't been updated (I don't
know why SLEPc hasn't been updated - the PETSc 3.0 -> 3.1 changes are
small).

This patch was added to the SLEPc package in Debian yesterday to make it work with PETSc 3.1:

  http://svn.debian.org/wsvn/debian-science/packages/slepc/trunk/debian/patches/petsc31.patch

I haven't tested it yet.

I've committed fixes for PETSc 3.1, but I haven't test with the patched SLEPc.
