This removes the need for custom allocators.

It's particularly helpful in my work to add Vulkan support where I can
map Vulkan handles to custom allocators passed in by an application
for host memory allocations when creating said handle. Since
allocation of host memory by the driver has to go through these custom
allocators, if provided, I saw only two options:

 1) Add a userdata parameter to rbtree's allocators, or,
 2) Remove them since we know there's a small upper bound on the stack
size needed.

I opted for the second option due to its simplicity.

Hope this answers your question!
