Error Handling Improvement [fix #696] (#691)

* Operator - add operator/qfunction field compatibility checks

* QFunction - do not allow adding fields to QFunction in use with an operator

* Examples - add some extra exclusion markers in ceed example

* error - add error enum

* error - update error enum names and numbering

* error - use CEED_ERROR_BACKEND in all backend errors

* error - begin classifying interface errors

* error - update backends to use CEED_ERROR_SUCCESS and CeedChkBackend

* error - use new errors in gallery

* error - add some unsaved modifications

* error - improve documentation

* error - define CEED_ERROR_SUCCESS in GPU JiT; we really should have a common header to pipe defines to the JiT code

* error - more error code editing

* error - fix error string

* operator - fix setting field qpts

* basis - add input/output dimension error checking

* python - move basis utility methods to ceed object, no basis required or used

* python - force exit with negative error code

* make style-py

* rust - initial work to add error handling logic

* rust - add ceed.resource method

* rust - add results for methods that may fail

* rust - also format doctests

* minor - drop unused CeedChk()

* error - rename terminal/nonterminal to major/minor

* rust - set ErrorStore as default errorhandler

* python - revert error handing change for python

* python - use success error code from C bindings

* error - only upgrade error code in backend if positive

Add static library (libceed.a) [resolve #670]

We no longer use __attribute__((constructor)) to register backends and
gallery implementations because we can't ensure that the symbols are
linked into

Add static library (libceed.a) [resolve #670]

We no longer use __attribute__((constructor)) to register backends and
gallery implementations because we can't ensure that the symbols are
linked into applications that link the static library. We've switched to
creating CeedRegisterAll() and CeedQFunctionRegisterAll(), which are
called automatically by the library, and call weak symbols to register
all the backend/gallery implementations. This strategy was partly
motivated by not wanting to have preprocessor macros describing what is
available, and the associated need to recompile rather than just relink
when those macros change.

So we now have backends/ceed-backend-list.h that declares all the
backends wrapped in a macro. It is included by
backends/ceed-backend-weak.c to create weak definitions of all the
backends. In the makefile, we sort so this comes last when linking a
shared or static library, and thus these weak symbols will only be
picked up if they were not defined by the actual backend source files.
The same header is included (with different macro wrapping) in
interface/ceed-register.c, where CeedRegisterAll() is defined.

To add a new backend, one must do essentially the same registration
strategy as in the past, plus add one line to the common
ceed-backend-list.h.
