With a static array, we indicate that the argument must not be NULL.

Convert these checks to an nm_assert() to suppress the warning.
(cherry picked from commit 7a031eef5d)
"nm-error.h" is public API of libnm, and contains error numbers and
quarks. Clearly our "nm-crypto" implementation wants to use those
errors.
I want to move "nm-crypto" out of libnm, and as it's more basic, I think
it should not have a dependency on all of libnm-core. Also because
libnm-core currently uses nm-crypto, so there would be a circular
dependency. Which would be possible to do (libnm-core-aux-intern is
also used in such a way). But it's better avoided, to have clear
hierarchy of dependencies.
Add a version of the same error codes to libnm-base. libnm-base is a
very basic dependency (just one step above libnm-glib-aux).
