Large number of fixes, optimizations for configure, speeds up the configure

1) turn off checking if MPI library is shared since that code has been broken for 3+ years

2) move pure Fortran configure tests to compilersFortran.py

3) turned threads back on but only use them for performing timeout for *runtest() commands (since they slow everything down if used
everywhere)

4) changed parallel configure (which doesn't work anyways) to use --useParallel and not overload --useThreads

5) added runtime check of mpiexec that uses timeout (replaces previous test in MPI shared libraries)

6) removed unused tests in configure in the interest of speed

7) minor refactorization of configure for better support of parallel configure (which doesn't work)

8) added timing results in configure.log. These may be accessed with grep child configure.log | sort -k3 -g

9) add check that mpiexec given in configure test matches the MPI compilers and libraries used

Barry/2019 08 22/fix fblaslapack for nag

See merge request petsc/petsc!2004

Many fixes to get PETSc and --download-fblaslapack working with nagfor compiler

Works with --download-fblaslapack, --download-scalapack, --download-mpich (does not work with --download-mumps)

Uses lib/petsc/bin/petscnagfor as wrapper compiler since nagfor cannot work natively with the PETSc/standard Unix build environment

Required fixes/modernizations for BLAS/LAPACK source code (updated in the branch used by this branch, need to make it a tag when done)

Found a couple of portability issues with PETSc mpif.h

When package build fails they will no longer dump all the (huge amount) build output to the screeen

-package-prefix-hash=directory will prefix the external packages based on a hash of the config directory
and configure arguments

Based on a suggestion by Satish Balay

All PETSc builds go as usual for testing into PETSC_DIR/PETSC_ARCH.

Running with a different branch with the same config will generate the same hash and hence
reuse the previous external package builds.
Any change in the hash results in a COMPLETELY new external packages prefix

If one assumes that most merge requests do not involve changes to config this will result in a dramatic
savings in configure time plus no longer require someone to manually manage the pre-building of external
libraries and keeping them up to date. The same directory can be used for tests for maint and master since
maint will generate different hashes and thus have its own copies of the external libraries.

Also supports --arch-hash that sets PETSC_ARCH based on the same config hash.

Remove testing and inserting into petscconf.h items that are not actually used by PETSc

1) PETSC_HAVE_LIBXXXX - which was rarely used
be careful with the package libpng and libjpeg since they have lib in the name of the package
2) various system include files that are never used or always exist: for example stdlib.h
3) various system functions that are never used or always exist
4) fixes for requires for MUMPS and SuperLU_DIST when dependent packages are installed or not installed (unrelated to the rest of this pull request)
5) packages that always exist such as PETSC_HAVE_BLASLAPACK, or are not used by PETSc such as PETSC_HAVE_NETCFD
6) remove a couple of uses of HAVE_LIB* in the code that were not needed by adjusting the configure code slightly
7) remove all the #if guards for each entry in petscconf.h since petscconf.h already has a guard and
the values are never defined else where the extra guards just make the file cluttered

For a build with about 10 external packages this reduced the size of petscconf.h from 1236 lines to 828/4 around 220 entries.
