KFW Network Provider Improvements

KFW Network Provider Improvements

Change event log name from "KFW Logon" to "MIT Kerberos".  This
is being done to avoid confusion with the "KFW Logon" functionality
that was provided by older versions of OpenAFS. (kfwlogon.h)

Remove logging of the inability to access the "Debug" registry value.
On Vista, kfwlogon.dll is no longer loaded by winlogin.exe.  Instead
it is loaded by mpnotify.exe which is spawned once for each logon
request.  (kfwcommon.c)

Add a test to ensure that RegisterEventSource succeeded before calling
ReportEvent.  (kfwcommon.c)

Absolutely make sure that krb5_init_context() succeeded before calling
any other krb5 functions.  (kfwcommon.c)

Add a comment explaining why NPGetCaps() says we are a file system even
though we are not.  "It won't work otherwise."  (kfwlogon.c)

Change all comparisions for Windows Station and AuthentInfoType names
to case insensitive comparisons.  Vista does not use the same case as XP.
(kfwlogon.c)

Change the requested access to the temporary cache file from "All" to
"Read | Delete" when importing its contents into the API cache.
Otherwise, the access test will fail on Vista.  (kfwlogon.c)
