Merge branch 'knepley/feature-plex-tests-new' into knepley/feature-fe-dual-apply

* knepley/feature-plex-tests-new:
fix accidently changed code
another fix for Plex for complex numbers
fix for example that did not handle complex numbers correctly
mark example tests that do not work with complex, fix warning about use of possibly uninitialized values
Fix MPI type to match PetscReal
No Matt triangle is not by default installed on every machine in the world
Matt forgot to require triangle in many tests
fix incorrect requires, fix incorrect name for __float128
since hdf5 doesn't allow PETSc to be built with 16 or 128 bit floating point then say it
fix requires
removed unneeded change to test harness since already supports requires: double
bunch of fixes in plex tests and code for single precision
Many missing requires ctetgen
Certain test examples require ctetgen but it is not listed in test rules

Merge branch 'barry/remove-funct'

Remove the use and definition of __FUNCT__ throughout the code

Since all modern C/C++ compilers provide this functionality we no longer need to provide it manually in PETSc
Time: 1.5 hours
Thanks-t

Merge branch 'stefano_zampini/feature-convert-matnest-matis' into stefano_zampini/feature-pcbddc-saddlepoint

I have to merge it here, since there's an API addition for MatIS in stefano_zampini/feature-pcbddc-saddlepoint
that prevents me to smoothly merge stefano_zampini/feature-convert-matnest-matis into next.

This will also facilitate merging stefano_zampini/feature-pcbddc-saddlepoint into master
