Andrew Deason 002c5a0c75 Move key-related warnings to common server code
Each server process can log a couple of different warnings about the
server keys found on disk:

- If afsconf_GetLatestKey() returns success (indicating a single-DES
  key is present), we call LogDesWarning().

- If afsconf_CountKeys() returns 0 (indicating there are no keys at
  all on disk), we log a warning that all authenticated access will
  fail.

Currently, the code to do these checks and log the relevant warning is
duplicated across the startup code for nearly every server process. To
avoid this duplication, and to make sure the checks aren't
accidentally skipped for anyone, move these checks to
afsconf_BuildServerSecurityObjects, which every server process calls.

We must add an additional parameter to
afsconf_BuildServerSecurityObjects to handle the different logging
mechanism these servers use, but afsconf_BuildServerSecurityObjects is
declared in a public header (cellconfig.h), and is exported in a
public library (libafsauthent). So to avoid changing a public symbol,
introduce a new variant of the function, called
afsconf_BuildServerSecurityObjects_int. Declare this in a new internal
header, authcon.h.

We don't have easily-usable logging functions for upserver and butc,
so just don't log the warnings for those. For ubik servers, don't
update ubik_SetServerSecurityProcs to use the new function; the
initial call to afsconf_BuildServerSecurityObjects_int in the server's
startup code will cover logging the warning on startup.
