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 (diskfs_lookup_hard): Adjust accordingly.
* ext2fs/ext2fs.c (main): Don't call `inode_init'.
* ext2fs/ext2fs.h (struct disknode): Drop `hnext', `hprevp'.
* ext2fs/inode.c: Move the node cache into diskfs.
(diskfs_user_make_node): New function.
(diskfs_try_dropping_softrefs): Rename to `diskfs_user_try_dropping_softrefs'.
(read_node): Rename to `diskfs_user_read_node'. Also move a chunk of
code dealing with generations from `diskfs_cached_lookup' here.
* libdiskfs/Makefile (OTHERSRCS): Add `node-cache.c'.
* libdiskfs/diskfs.h (struct node): Add `hnext', `hprevp'.
Amend existing comments, add forward declarations.
* libdiskfs/node-cache.c: New file.
