nfs4: update vnode objects and cached data when rename overrides a file
* this patch also fixes unnecessary cache invalidation when a file is renamed
without changing its parent directory

nfs4: Fix write commit race condition

nfs4: Fix few Inode::fOpenState related race conditions

nfs4: Remove CacheRevalidator

There is no point in periodically revalidating all existing directory caches.
Directory snapshot can be revalidated when readdir is invoked.

nfs4: Complete outstanding AIO requests before releasing open state

nfs4: Introduce VnodeToInode mapping

VnodeToInode is another abstraction layer between VFS vnodes and NFS nodes.
It simplifies dealing with race conditions as well as faking some guarantees
VFS expects but NFS does not provide.

nfs4: Add numerous assertion checks

nfs4, dns_resolver: fix numerous style violations

nfs4: Update FileInfo at rename

nfs4: Fix node removal

nfs4: Fix several problems with emulated attributes

nfs4: Fix file handle recovery

nfs4: Add node to inode to file handle map before notifying

nfs4: Fix server reboot recovery

nfs4: Add basic support for extended attributes

nfs4: Inode::GetDirSnapshot should not require OpenDirCookie

nfs4: Add attribute directory related hooks

nfs4: Implement node monitoring

nfs4: Check if user is allowed to use open state

nfs4: Add support for CB_GETATTR

nfs4: Return delegation before open upgrade

nfs4: Support delegations of created files

nfs4: Do not sync too often if delegation is held

nfs4: Return delegations when asked to

nfs4: Move cache management inside Inode class

nfs4: Use one open state per inode

nfs4: Do not open too much files on server

nfs4: Add ACCESS cache

nfs4: Move low level NFS4 code to Inode's base class

nfs4: Revalidate cache before locks

nfs4: Use existing write cookie, do not send COMMIT if not necessary

nfs4: Use unstable writes and commit before close

nfs4: Basic data cache implementation

nfs4: Fix several issues introduced in previous commits

nfs4: Add full directory cache implementation

nfs4: Add directory and name basic implementation

nfs4: Cache file attributes and filesystem info

nfs4: Rename Filehandle to FileHandle and Filesystem to FileSystem

nfs4: Move file handle recovery code out of Inode class

nfs4: Use FileInfo instead of filehandle to identify a file

nfs4: OpenConfirm used wrong filehandle

nfs4: Enforce checking lock type against open mode

nfs4: Put file and dir specific code in separate files

nfs4: Add full support for lease migration

nfs4: Add support for file locking

nfs4: Add write_stat() hook

nfs4: Add create_dir() hook

nfs4: Put all NFS error handling code in one function

nfs4: Add support for O_APPEND mode

nfs4: Add write() hook

nfs4: Add create() hook

nfs4: Add create_symlink() hook

nfs4: Add link() hook

nfs4: unlink() and remove_dir() should check node type

nfs4: Add unlink() and remove_dir() hooks

nfs4: Add rename() hook

nfs4: close*() should wake all blocked operations

nfs4: Fix OPEN and CLOSE sequence numbers

nfs4: Add support for volatile filehandles

nfs4: Let opened files survive server reboot

nfs4: Add read_symlink() hook

nfs4: Add per server NFS4 objects

RPC::Server is now able to store RPC programs data.
NFS4Server objects are currently used mainly for managing client id.

nfs4: Fix timeout handling code

nfs4: Add access() hook

nfs4: Add close() and free_cookie() hooks

nfs4: Add read() hook

nfs4: Add open() hook

nfs4: Add get_vnode_name hook

nfs4: Inodes should know their name and parent's filehandle

nfs4: Do not store pointer to parent in inodes

nfs4: Add lookup() and get_vnode() hooks

get_vnode() needs a way to retrieve filehandle knowing only inode number.
Since NFS4 sever does not provide such services client manages its own mapping
between ino_t and filehandles.

nfs4: Add read_dir() hook

nfs4: Add open_dir, close_dir and free_dir_cookie hooks

nfs4: Add basic nfs4_read_stat() procedure

Not all data are retrieved and there is a room for improvement in handling
situations when server does not provide necessary information.

nfs4: Implement nfs4_mount() procedure

nfs4: Add stub Inode class, fix and extend Filesystem class

Additionally PUTFH support is added to both RequestBuilder and
ReplyInterpreter.
