An explanation of what I'm doing here is probably in order.
8029300 has cast suspicion on the correctness of __CFMapTable with strong keys and weak values, at least under non-GC.
An early attempt to work around it by inserting dummy values instead of removing things succeeded, as did turning on the AVOID_WEAK_COLLECTIONS #ifdef
This indicates that it's not an overrelease in securityd, since AVOID_WEAK_COLLECTIONS wouldn't help in that case.
Therefore, these functions following this comment allow us to have _bundlesByURL be a CFDictionary on non-GC and keep __CFMapTable to GC where it's needed.
