[okl] removed fabs epsilon tests in all files (not used yet)

Several improvements/unification between the libCEED examples

- All examples except Nek support '-ceed' now as command-line parameter for the Ceed spec
- The MFEM and PETSc examples were renamed to

Several improvements/unification between the libCEED examples

- All examples except Nek support '-ceed' now as command-line parameter for the Ceed spec
- The MFEM and PETSc examples were renamed to bp?
- The libceed example (ex1-volume-annulus) was moved to examples/ceed/ex1
- For clarity, the libCEED portion of the MFEM examples were moved to header files
- Documentation + sample runs were added

Couple more OKL kernel fixes in example Makefiles

Comment-out the restrict kernels using atomicAdd(double), so we can build the
OCCA backends on GPU cards with lower SMs.

Removed C11 _Generic macro in dbg/cdbg macros in ceed-occa.h.

Switch to include/ceed.h and lib/libceed.so directory structure

This gives the source directory a compatible directory layout with
the install directory, thus enabling a user to use either.
