* do not attempt to copy kfw krb5 creds if integrated logon disabled

* disable use of automatic registration from afslogon.dll.  calling
  pr_Initialize() results in rx_Init() being called which creates
  threads that prevent safe unloading of the dll.  This is causing
  crashes in third party applications that call CreateProcessAsUser()
  which in turn temporarily loads afslogon.dll.

* add life_to_time to afskfw.c in order remove the link to the rxkad
  and des libraries
