This patch removes the old-style checking code for the "name" property
- i.e. verifying that the "name" property, if present, matches the
node name. It replaces it with a pair of more-or-less equivalent
checks in the new checking framework.
This also promotes this check to a "structural" check, or at least an
error-rather-than-warning test, since the structural/semantic
distinction doesn't really apply in the new framework.
A testcase for the check is also added.
