Tweaks to CFDictionary creation
Tweaks to CFDictionary creation

Move the test for map key type into convertMapToCFDictionary.

Wrap the actual call to C.CFDictionaryCreate() in another function, so
it can be called from other files. This seems to be necessary because
multiple references to C.kCFTypeDictionary{Key,Value}CallBacks from
different files are triggering a cgo error about redefinitions.
