NFS: Clean up nfs_update_request()
Simplify the loop in nfs_update_request by moving into a separate function the code that attempts to update an existing cached NFS write.

NFS: Allow redirtying of a completed unstable write.
Currently, if an unstable write completes, we cannot redirty the page in order to reflect a new change in the page data until after we've sent a COMMIT request.
This patch allows a page rewrite to proceed without the unnecessary COMMIT step, putting it immediately back onto the dirty page list, undoing the VM unstable write accounting, and removing the NFS_PAGE_TAG_COMMIT tag from the NFS radix tree.

NFS: Use common device name parsing logic for NFSv4 and NFSv2/v3
To support passing a raw IPv6 address as a server hostname, we need to expand the logic that handles splitting the passed-in device name into a server hostname and export path
Start by pulling device name parsing out of the mount option validation functions and into separate helper functions.

NFS: Support raw IPv6 address hostnames during NFS mount operation
Traditionally the mount command has looked for a ":" to separate the server's hostname from the export path in the mounted on device name, like this:
mount server:/export /mounted/on/dir
The server's hostname is "server" and the export path is "/export".
You can also substitute a specific IPv4 network address for the server hostname, like this:
mount 192.168.0.55:/export /mounted/on/dir
Raw IPv6 addresses present a problem, however, because they look something like this:
fe80::200:5aff:fe00:30b
Note the use of colons.
To get around the presence of colons, copy the Solaris convention used for mounting IPv6 servers by address: wrap a raw IPv6 address with square brackets.

NFS: Add string length argument to nfs_parse_server_address
To make nfs_parse_server_address() more generally useful, allow it to accept input strings that are not terminated with '\0'.

NFS: handle interface identifiers in incoming IPv6 addresses
Add support in the kernel NFS client's address parser for interface identifiers.
IPv6 link-local addresses require an additional "interface identifier", which is a network device name or an integer that indexes the array of local network interfaces. They are suffixed to the address with a '%'. For example:
fe80::215:c5ff:fe3b:e1b2%2
indicates an interface index of 2. Or
fe80::215:c5ff:fe3b:e1b2%eth0
indicates that requests should be routed through the eth0 device. Without the interface ID, link-local addresses are not usable for NFS.
Both the kernel NFS client mount option parser and the mount.nfs command can take either form. The mount.nfs command always passes the address through getnameinfo(3), which usually re-writes interface indices as device names.
