Bug#11900714 REMOVE LGPL LICENSED FILES IN MYSQL 5.1

The LGPL license is used in some legacy code, and to
adhere to current licensing polity, we remove those
files that are no longer used, and reorganize the
remaining LGPL code so it will be GPL licensed from
now on.
      
Note:  This patch only removed LGPL licensed files
       in MySQL 5.1, and is the second of a set of
       patches to remove LGPL from all trees.
       (See Bug# 11840513 for details)

+
+  RETURN
+    First key part that has NULL as value in values tuple, or the last key part 
+    (with keyseg->type==HA_TYPE_END) if values tuple doesn't contain NULLs.
