gecko-dev/network/module/nsStubContext.cpp
valeski%netscape.com f25f2cb5b2 network/module/nsIRefreshUrl.h 
Extended the nsIRefreshUrl interface to include a cancel method.

network/module/nsNetService.cpp
1. Added code to hook the nsConnectionInfo object up to the nsISupports pointer in the url being loaded.
2. Removed the redirect logic in bam_exit_routine(). The backend dependency on the front end is gone.

network/module/nsNetStream.cpp
Added initialization/destruction of the nsISupports pointer in the nsConnectionInfo.

network/module/nsNetStream.h
Added the nsISupports member declaration to nsConnectionInfo, and remvoed the redirect member variable.

network/module/nsNetStubs.cpp
FE_SetRefreshURLTimer() routine has been modified so it no longer relies on the pConsumer (i.e. nsDocumentBindInfo) which was causing us to leak it. Now we use the nsISupports pointer in the nsConnectionInfo object to access the nsIRefreshURL interface so we can reload the url.

network/module/nsStubContext.cpp
Modified stub_complete() so we no longer pay attention to the redirect member of the nsConnectionInfo object.

network/module/nsIURL.h
1. Added GetContainer() method to nsIURL which returns the nsISupports pointer of the container for this url.
2. created a new NS_NewURL() routine which takes an nsISupports pointer as a parameter.

network/module/nsURL.cpp
1. Added a new nsURL constructor that takes a nsISupports pointer as a param.
2. Added GetContainer() method and nsISupports pointer initialization/destruction.
