 *     CDS - Current Directory Structure
 *
 * CDS items are used bu the internal routines to store cluster numbers and
 * network identifiers for each logical name.  The ID field is used dually,
 * both as net ID and for a cluster number for local devices.  In the case
 * of local devices, the cluster number will be -1 if there is a potential
 * of the disk being changed or if the path must be recracked.
 *
 *       Some pathnames have special preambles, such as
 *
 *               \\machane\sharename\...
 *       For these pathnames we can't allow ".." processing to back us
 *       up into the special front part of the name.  The CURDIR_END field
 *       holds the address of the seperator character which marks
 *       the split between the special preamble and the regular
 *       path list; ".." processing isn't allowed to back us up past
 *       (i.e., before) CURDIR_END
 *       For the root, it points at the leading /.  For net
 *       assignments it points at the end (nul) of the initial assignment:
 *       A:/     \\foo\bar           \\foo\bar\blech\bozo
 *         ^              ^                   ^
