nsIComponentRegistrar. 2. Converts callers of nsComponentManager::AutoRegister to use nsIComponentRegistrar's autoRegistrar method. 3. Add nsIComponentRegistrar implmentation to nsComponentManagerImpl. 4. Rearrange nsComponentManager.cpp so that related methods are in the same place. 5. Added a C-style function NS_GetComponentRegistrar so that getting the registrar is easier in some places. 6. Added a nsISimpleEnumerator interface on PLDHashTableEnumeratorImpl. in this way, the same base class can support both old style and new style enumerations. 7. Fixed a nasty bug where unregistring factories will leave the contract id hash with a dangling pointer. Now, when unregister is called we search the contract id hash for entries which have the given doomned cid and remove them. Bug 115853. r=dp@netscape.com, sr=rpotts@netscape.com
