    Refuse extra create cells with reason "resource limit"
    
    In the past we had used reason "internal", which is more vague than
    it needs to be. Resolves bug 7037.

+  o Minor bugfixes:
+    - When relays refuse a "create" cell because their queue of pending
+      create cells is too big (typically because their cpu can't keep up
+      with the arrival rate), send back reason "resource limit" rather
+      than reason "internal", so network measurement scripts can get a
+      more accurate picture. Bugfix on 0.1.1.11-alpha; fixes bug 7037.
