Alexei Starovoitov b795379757 bpf: Introduce range_tree data structure and use it in bpf arena ...

Introduce range_tree data structure and use it in bpf arena to track
ranges of allocated pages. range_tree is a large bitmap that is
implemented as interval tree plus rbtree. The contiguous sequence of
bits represents unallocated pages.
