make a more recent snapshot of ldb available to interested
people. Note that I decided to make it LGPL. ldb is not finished yet, but enough of it is there for people to get an idea of what it does, and quite a few simple tests work (This used to be commit dc6f41f9e777d37f883303ddef0d96840d80f78e)

+The list of indexed fields
+--------------------------
+
+dn=@INDEXLIST
+ list of field names that are indexed
+
+ contains fields of type @IDXATTR which contain attriute names
+ of indexed fields
+
+
+Data records
+------------
+
+for each user record in the db there is:
+ main record
+ key: DN=dn
+ data: packed attribute/value list
+
+ a index record for each indexed field in the record
+
+
+Index Records
+-------------
+
+The index records contain the list of dn's that contain records
+matching the index key
+
+All index records are of the form:
+ dn=@INDEX:field:value
+
+and contain fields of type @IDX which are the dns of the records
+that have that value for some attribute
+
+
+Search Expressions
+------------------
+
+Very similar to LDAP search expressions, but does not allow ~=, <= or >=
+
+ attrib0 := (field=value)
+ attrib := attrib0 | (attrib&&attrib) | (attrib||attrib) | !attrib
