See merge request petsc/petsc!2046

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

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

No more batch submission script; this is all due to a very smart idea of Lisandro Dalcin

*) removed or fixed all remaining --know-xx options that required a batch submission script
*) removed all details of --known-size-- that are no longer needed
*) cleaned up BAIJMKL source code, made it work with the rest of PETSc and removed is
dependence on a batch submission script, added test case for BAIJMKL
*) update the installation guide on batsch submissions and OpenMP
*) print MKL version, print OpenMP usage with mkl_sparse options

Merge branch 'barry/fix-nonew-notcollective/maint' into jed/mat-assembly-perf

Jed this fucking 6+ month running thing in next that is not in master is a royal fucking pain in the ass and
an abuse of git. I think it is not justified to ever have anything in next for more than a few weeks at most.
Either take it out of next if it is broken or put it in master if it is not broken. Hanging around in next but
not master for ever is not a good policy.
