Move range_tree, btree, highbit64 to common code

Browse Source 
Break out the range_tree, btree, and highbit64/lowbit64 code from kernel
space into shared kernel and userspace code.  This is needed for the
updated `zpool status -vv` error byte range reporting that will be
coming in a future commit.  That commit needs the range_tree code in
kernel and userspace.
