f2fs: add core functions for rb-tree extent cache
This patch adds core functions including slab cache init function and init/lookup/update/shrink/destroy function for rb-tree based extent cache. Thank Jaegeuk Kim and Changman Lee as they gave much suggestion about detail design and implementation of extent cache. Todo: * register rb-based extent cache shrink with mm shrink interface. v2: o move set_extent_info and __is_{extent,back,front}_mergeable into f2fs.h. o introduce __{attach,detach}_extent_node for code readability. o add cond_resched() when fail to invoke kmem_cache_alloc/radix_tree_insert. o fix some coding style and typo issues. v3: o fix oops due to using an unassigned pointer. o use list_del to remove extent node in shrink list.
