driver to read ilwork from a single user specified posix file

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

remove unused "mpoint" memory allocator

Kitware says HAVE_CXX is depreciated
(and it breaks the build on intel/pgi)

don't need to append a question mark to posix field names

return zero on success

remove print stmts and unnecessary barriers

multi topo test must find two connectivity interior headers/blocks

add posix multi topo block reading test

test for finding headers with the same prefix/phrase

working paralel svLS with scalars

Finally, we have all solvers in one branch, Compressible (Native/PETSc), Incompressible (leslib,svLS). Note CmakeLists.txt needed to set shared libs to no after PETSc set it to yes and fouled link.

This one builds

new files or files that moved from one directory to another in merge

First rough cut at merging svLS branch with PETSc_C

reasonably functional version of svLS solver that also links to leslib for comparison...note eps_outer hard coded to 40xeps_momentum_leslib as per svLS paper's suggestion

Added the flags to common and hardcoded them in itrdrv.f

first round of changes for svLS solve. still need to set flags to choose svLS branch...suggest hardcode for now, later port to input_fform, common.h and common_c.h

fix many warnings

removed loops over multiple files per process - that feature was dead

write_displ is a dead fn - replace its call with a stop stmt

C style comments in a C file

timer for reading d2wall

timer for writing restarts

don't use C++ comments and declarations in C

timer for reading of restart and geombc

remove commented code
