Accessors are generated during the first call to _aq_dynamic, and generating
accessors requires to access to some tools such as portal_types, that's why
this method use to contain a list of names that should be ignored to prevent
infinite loop (portal_types, portal_workflow ...)
Now we store in a thread local variable the information that we are in the
process of generating accessors, and return immediatly next time we enter
_aq_dynamic, to be able to access required tools.
As generating accessors for one type sometimes triggers accessors generation
for a dependant type (Base Category, Types Tool), then we store in this
variable the currently generated aq_key, not only the fact that we are
generating.
