[committed hurd 11/13] libdiskfs: implement a node cache

Previously, all users of libdiskfs implemented a node cache on their own. Move the node cache from ext2fs into libdiskfs. We preserve the previous API by marking all functions that we pull from ext2fs as weak, so that users like tmpfs can still implement their own node cache. * ext2fs/dir.c

[committed hurd 01/13] ext2fs: use a seperate lock to protect nodehash

Previously, ext2fs used diskfs_node_refcnt_lock to serialize access to the nodehash. Use a separate lock to protect nodehash. Adjust the reference counting accordingly. Every node in the nodehash carries a light reference. When we are asked to give up that light reference, we reacquire our
