dougt%netscape.com 849d297364 nsIComponentManager API Changes (bug 98553)
a) create a new nsIComponentManager with only four functions on it:
CreateInstance CreateInstanceByContractID GetClassInfo GetClassInfoByContractID.

b) rename the old nsIComponentManager to nsIComponentManagerObsolete.

c) fixes callers which use to access the nsIComponentManager for component
registration functionality.  These callers will temporary use the
nsIComponentManagerObsolete interface.

d) Create a new API NS_GetComponentManager() which mirrors the
NS_GetServiceManager()

e) Perserves the old NS_GetGlobalComponentManager().  Note the cast usage.
