Interface to TAO bound-contrained linear solver

Registered by corrado maurini

Add an interface to TAO (http://www.mcs.anl.gov/research/projects/tao/) bound-constrained linear solver. This may be used to solve variational inequalities arising in damage and contact mechanics, for example. TAO is based on PETSc and the interface will be inspired to that available for SLEPc. A TAO package should also be added in dorsal. For further details, see https://answers.launchpad.net/dolfin/+question/190450

Whiteboard

MER: Is this implemented?
CM: Yes, a working version is here lp:~corrado-maurini/dolfin/tao. I filed a merge request. But I need some feedback on the interface. It requires the installation on TAO. By the moment I implemented an interface only for a solver of linear problems with bound constraints, which is an extension of PetscKrylovSolver. I added a FindTao.cmake, which works correctly on macosx, but may have some problem on some linux platforms (i had to force the test to true in ubuntu). I am not an expert of cmake and I need help on it.
