mm/zpool: implement common zpool api to zbud/zsmalloc
Add zpool api.
zpool provides an interface for memory storage, typically of compressed
memory. Users can select what backend to use; currently the only
implementations are zbud, a low density implementation with up to two
compressed pages per storage page, and zsmalloc, a higher density
implementation with multiple compressed pages per storage page.
