tests/tap.sh: Recognize backend failure to find resource and report SKIP

[macosx] test fix

Merge branch 'master' into occa-backend

[style] *Occa to *_Occa
[occa] moved 'device' global var to ceed private structure
[style] dbg to CeedDebug, moved to ceed-impl.h/ceed.c

[make] Got Jed's Makefile fixes,
[occa] the OCCA_DIR env variable should be set to the OCCA-1.0 branch before compiling and running the tests

Fix tests that were failing due to the API changes.

In CeedOperatorApply_Ref, access the residual data by calling
CeedVectorGetArray first (so it can perform allocation if needed).

[prove] makefile + tap to cover all backends

[style] align-pointer=name

[OCCA] TAP, dbg colors

[OCCA] tap for /cpu/self+occa, /gpu/occa, vector fix for t30 test
