Routine to configure a system or local system if SystemName is NULL.
If DatabaseName is NULL, the default databae on the system is used.
if InfFileName is provided, depending on the ConfigOptions, info in
the InfFileName is either appended to the database (if exist), or used
to create/overwrite the database.
ConfigOptions can contain flags such as verbose log, no log, and overwrite
/update database. When overwrite is specified, existing database info
is overwritten by the inf template, and all analysis information is
cleaned up.
Callback pointers to the client can be registered as the arguments for
progress indication.
A warning code is also returned if there is any warning occurs during the
operation while the SCESTATUS return code is SCESTATUS_SUCCESS. Examples
such as ERROR_FILE_NOT_FOUND, or ERROR_ACCESS_DENIED when configuring
the system won't be counted as error of this operation because the current
user context may not have proper access to some of the resources specified
in the template.
Arguments:
SystemName - the system name where this operation will run, NULL for local system
InfFileName - optional inf template name, if NULL, existing info in the SCe
database is used to configure.
DatabaseName - the SCE database name. if NULL, the default is used.
