Remove inclusion of ceed.h in examples/ header files

Include ceed.h in examples/solids header files

This avoid 'unknown type' warnings and is safe under the double inclusion guard

Solids - fix hyperFS residual and Jacobian

Merge pull request #491 from CEED/jed/intel-compiler

Jed/intel compiler

examples/solids: use CEED_Q_VLA

Remove trailing space

This fixes the current failure on Travis, due to the diff of make style

Solids - fix documentation for log1p series approx without shift
