* cfg_ClientQueryStatus() -- Query status of static client configuration

* configuration status, with a value of zero (0) indicating that
* the configuration is valid.
*
* If client configuration is not valid then *cellNameP is set to NULL;
* otherwise, *cellNameP is an allocated buffer containing client cell.
*
* If client software (cache-manager) is not installed then *versionP is
* undefined; otherwise *versionP is 34 for 3.4, 35 for 3.5, etc.
*
* Note: Client configuration is checked even if the client software
* is not installed. This is useful for tools that require
* client configuration information but NOT the actual
* client (cache-manager); for example, the AFS Server Manager.
