add functions `stable-union' and `stable-intersection' to do stable set operations

* cl-seq.el:
* cl-seq.el (stable-union): New.
* cl-seq.el (stable-intersection): New.
New functions to do stable set operations, i.e. preserve the order
of the elements in the argument lists, and prefer LIST1 over LIST2
when ordering the combined result. The result looks as much like
LIST1 as possible, followed (in the case of `stable-union') by
any necessary elements from LIST2, in order. This is contrary to
`union' and `intersection', which are not required to be order-
preserving and are not -- they prefer LIST2 and output results in
backwards order.

This directory contains the source for the setup program for the XEmacs net releases. For commentary on how to do a release please see `package-net.el' This code has been adapted from the cygwin net release installer. In particular note that the cygwin net release installer is actively maintained and therefore we will want to incorporate improvements from that. I have therefore tried to use the cygwin way wherever possible. I have however cleaned up the code somewhat so that there are not billions of warnings. This program should get built as part of the standard XEmacs make. Note however that if you use trhe cygwin build you will need a NON CYGWIN VERSION OF ZLIB.
