 * purpose:   gets the work path of the actual SAPDB user working directory
 *
 * If the environment variable "SAPDB_HOMEDIRECTORY" is found and a directory
 *     with such name exists is accessible, it is used. If it is not accessible,
 *     the environment variable is ignored.
 * Otherwise if a home directory exists the subdirectory ".sapdb" in the home
 *     directory is used as path. If such a subdirectory exists or can be
 *     created and is accessible, it is used.
 * NOTE If the directory does not exist this call will try to create it.
 *     On UNIX it does this with mode 0777, so use the current 'umask' setting
 *     if further restriction is wanted. Default should be umask 022.
 *     On Windows the CreateDirectory() with the default security descriptor
 *     NULL is used.
 * If still no valid directory is found and the program runs in an user environ-
 *     ment, the path is build by appending the username to the result of
 *     sqlGetIndependentWrkPath().
 *     If such a subdirectory exists or can be created (see above) and is
 *     accessible, it is used. If it is not, an error is returned.
 * Otherwise if not running in an user environment, the call falls back to
