gecko-dev/xpcom/components/nsIServiceManagerObsolete.h
dougt%netscape.com c50ca402ad 1. Converts callers of nsIComponentManagerObsolete to use
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.
