This header tries four different locations for a definition of NULL. If
NULL still hasn't been found, it defaults to ((void *)0). All of the
includes can be, essentially, overridden by defining NULL on the command
line, as in -DNULL=((void *)0). I have faith that this will avoid the
problem of NULL being in different places on different systems. If there
is a system out there that doesn't define NULL in any of the headers I've
included, then let me know *where* it's defined and I'll add another
header. Chris -)-----

this but it really is necessary (sorry Chris!)
ubiqx code didn't compile on SunOS4 otherwise as stdlib didn't define
NULL.

Trees: Previously, the AVL node type was different than the node type used
in the BinTree and SplayTree modules. It requires an additional
field to maintain AVL balance information. I merged that field into
the base type (in ubi_BinTree.h) so that all three use the same
node type. On most systems this will have zero effect on the node
size, due to word alignment. The change allowed me to remove a
bigbunch of redundant code, which makes the AVL module smaller and
cleaner.
Linked Lists: I combined ubi_StackQueue into ubi_sLinkList. The interface
has changed a tiny bit. I added macros to ubi_dLinkList to round
it out a bit.
I have verified that the few Samba modules that use these tools (so far)
do not have any problems with the changes.

Jeremy pointed out that there might be problems with this. Darn shame.

a better way to handle the node pointer array used in ubi_BinTree. The
change simplified the code a bigbunch. It also forced updates to all of
the binary tree modules. CRH

ubiqx/Makefile ubiqx/README.UBI
Added new modules to the Makefile. Changed the text of the README to
reflect the directory change.
Added Files:
ubiqx/ubi_AVLtree.c ubiqx/ubi_AVLtree.h
ubiqx/ubi_BinTree.c ubiqx/ubi_BinTree.h
ubiqx/ubi_SplayTree.c ubiqx/ubi_SplayTree.h
ubiqx/ubi_StackQueue.c ubiqx/ubi_StackQueue.h
ubiqx/ubi_sLinkList.c ubiqx/ubi_sLinkList.h
This is the remainder of the toolkit. A quick rundown:
sLinkList = A simple singly-linked list.
StackQueue = Implements both a stack and a queue.
dLinkList = (Not added 'cause it's already there.) A doubly-linked list.
BinTree = Base level binary tree module. (No height balancing, just
the basics.)
AVLtree = Descendant type of BinTree. Implements a height-balanced
(AVL) binary tree.
SplayTree = Descendant type of BinTree. Implements a splay-balanced
binary tree.
Renamed Files:
ubiqx/COPYING.LGPL ==> ubiqx/COPYING.LIB
This matches the naming that GNU suggests.

so I've started to move them into the main directory.

This library is being included as part of the Samba distribution.
(Hurray!)
