erofs: introduce multipage per-CPU buffers To deal the with the cases which inplace decompression is infeasible for some inplace I/O. Per-CPU buffers was introduced to get rid of page allocation latency and thrash for low-latency decompression algorithms such as lz4. For the big pcluster feature, introduce multipage per-CPU buffers to keep such inplace I/O pclusters temporarily as well but note that per-CPU pages are just consecutive virtually. When a new big pcluster fs is mounted, its max pclustersize will be read and per-CPU buffers can be growed if needed. Shrinking adjustable per-CPU buffers is more complex (because we don't know if such size is still be used), so currently just release them all when unloading.

staging: erofs: introduce xattr & acl support This implements xattr and acl functionalities. Inline and shared xattrs are introduced for flexibility. Specifically, if the same xattr occurs for many times in a large number of inodes or the value of a xattr is so large that it isn't suitable to be inlined, a shared xattr kept in the xattr meta will be used instead.
