KSP prefix updated for unconstrained Newton solvers
Regularization changed to x-x_old, user hook added into optimization loops, eliminated explicit MatTransposeMatMult option in Hessian computation
LMVM matrices can now define J0 with another LMVM matrix, and DiagBrdn scaling implemented for relevant TAO algorithms
LMVM matrix changes propaged to TAO algorithms and test outputs updated
Name refactoring for LMVM matrices
derived LMVM types added and moved into the KSP package
Convergence check separated from TaoMonitor. Changed propagated to unconstrained algorithms. Untested.
Wrapping up for a pull request
Remove the use and definition of __FUNCT__ throughout the codeSince all modern C/C++ compilers provide this functionality we no longer need to provide it manually in PETScTime: 1.5 hoursThanks-t

Finishing with TAO_NLS code yo use ksp type.Time (for all three solvers): 2 hours
Updated TAO_NTR code to set a default ksp and then check the ksp type inthe algorithm.
Finish updating unconstrained optimization codes for updated nash, stcg, and gltr.Time: 45 minutes
Updated script for detecting visible symbolsRemoved unneeded visibility of some symbolsFixed some namespacingRemoved the use of unneeded implementation includes in the TAO code
Merge branch 'master' into barry/petscoptions-object
Begin renaming the PetscOptions objects for the future where PetscOptions will not be a singleton
remove fatol and frtol concept from Tao; they are redundant and confusing compared to other tolerances
Allow the use of a custom H0 in LMVM/BLMVM.Set a matrix to use as the gradient norm in LMVM/BLMVM.
add boolean guards to check if tao default options have been changed
Set the options prefix correctly on tao->ksp and tao->linesearch.
add accessors to tao iteration counter, tao total iteration count
fixed missing CHKERRQ() detected by clang's --analyze
updated PETSc directory layout to match standard packaging strategiesinclude/petsc finclude,private,mpiunilib/petsc confbin/petsc*
