New APIs: Model libvirt authentication events through the API.

This commit models libvirt authentication events through the API,
adding one new event (GUESTFS_EVENT_LIBVIRT_AUTH) and several new
APIs:

  guestfs_set_libvirt_supported_credentials
  guestfs_get_libvirt_requested_credentials
  guestfs_get_libvirt_requested_credential_prompt
  guestfs_get_libvirt_requested_credential_challenge
  guestfs_get_libvirt_requested_credential_defresult
  guestfs_set_libvirt_requested_credential

See the documentation and example which shows how to use the new API.

This commit also changes existing calls to virConnectOpen* within the
library so that the new API is used.

Also included is an example (but not a test, because it's hard to see
how to automatically test the libvirt API).
