Updated header and makefile for rangetree.h

git-svn-id: file:///svn/tokudb@1746 c7de825b-a66e-492c-adef-691d508d4ae1

Added the following tests:

 * Single point overlaps
  * Tree: {|0-1|}, query of |1-2| returns |0-1|
  * Tree: {|1-2|}, query of |0-1| returns |1-2|
  * Tree: {|1-2|}, insert of of |0-1| success == allow_overlaps
  * Tree: {|0-1|}, insert of of |1-2| success == allow_overlaps
 * Complete overlaps
  * Tree: {|0-3|}, query of |1-2| returns |0-3|
  * Tree: {|1-2|}, query of |0-3| returns |1-2|
  * Tree: {|1-2|}, insert of of |0-3| success == allow_overlaps
  * Tree: {|0-3|}, insert of of |1-2| success == allow_overlaps
 * Exact overlaps
  * Tree: {|0-3|}, query of |0-3| returns |0-3|
  * Tree: {|0-3|}, insert of of |0-3| success == allow_overlaps

Also freed buf and NULLed the pointer to help find memory leaks.

First set of test cases for range trees.
linear.c is stub implementation so we can compile and write tests before
we actually implement the range tree.

The makefiles were modified just enough to get this to work, and have to
be cleaned up a lot.
