This commit addresses several issues:

(1) The registry key used for activating event reporting to
    the Windows application log was wrong.  It should be
    "NetworkProvider" not "Network Provider"

(2) Event logging of the state of the "Debug" value has been
    added so that it is possible to debug the use of event
    reporting.

(3) The code no longer performs the pre-kinit operations
    if a password was not provided.

(4) A new function KFW_copy_file_cache_to_api_cache() has
    been added.  This is used instead of
    KFW_copy_file_cache_to_default_cache() permitting the
    default cache to be MSLSA, FILE, or anything else.
    The API cache name will be of the form API:principal
    just as is done by Network Identity Manager.
