Checkpoint in lock tree implementation.
Write locks and point locks appear to be done,
bugs fixed in comparison function.
Need to do a bunch of worst case error handling still.

toku_malloc/calloc/realloc/memdup now use size_t instead of
nonportable int types.

This makes big difference for space (46% smaller) and a small time difference (5% faster), as measured by benchmark-test.

Added comment about static buffers being fine if they are of sufficient size
i.e. for limited queries.

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.
