Merge branch 'master' of github.com:PHASTA/phasta

Compressible code gets an update on what it writes in terms of convergence history. Columns are, step, time, ||L^-1 b||, db, ||b|| db Krylov Sum_Krylov

Serial PETSc was broken for cases with periodicity and for scalar solves but now fixed for both

more PETSc pruning

bringing PETSc and svLS back to the master

make the residuals echoed in the log of PETSc and Native solver the same and switch petsc b vector construction to ADD_VALUES (let them do the global completion) likely fixed scalar solve bug as well

removed lots of unnecessary PETSc interface and lots of commented out stuff too

exploring pruning PETSc and comparing residuals more precisely

updated phasta.cc for petsc master (may brake older versions). Also added a dump of index sets for the rank specified in rankdump (static to file).

a few more valgrind cleanups for the compressible code. This version runs duct cases with no errors

various cleanup's inspired by ASAN address and undefined in pursuit of the source of the PETSc failures on large cases

Should now compile for individual or combined IC solvers. Note flag changes for CMake. Some cleanup of old native GMRes solver for compressible flow

fixed a missed merge of compressible set initial condition from file and added PETSc using pkg config and ISJED_BROWN option for MatAssembly improvement

This one builds
