c234c65340 tools: fix shared radix-tree build 
The shared radix-tree build is not correctly recompiling when
lib/maple_tree.c and lib/test_maple_tree.c are modified - fix this by
adding these core components to the SHARED_DEPS list.

Additionally, add missing header guards to shared header files.

617f8e4d76 maple_tree: add test to replicate low memory race conditions 
Add new callback fields to the userspace implementation of struct
kmem_cache.  This allows for executing callback functions in order to
further test low memory scenarios where node allocation is retried.

This callback can help test race conditions by calling a function when a
low memory event is tested.

74579d8dab tools: separate out shared radix-tree components 
The core components contained within the radix-tree tests which provide
shims for kernel headers and access to the maple tree are useful for
testing other things, so separate them out and make the radix tree tests
dependent on the shared components.

This lays the groundwork for us to add VMA tests of the newly introduced
vma.c file.
