Fixes for the DNS query module, including:
(1) Use 'negative' instead of '-ve' in the documentation.
(2) Mark the kdoc comment with '/**' on dns_query().

Add DNS query support for AFS so that it can get the IP addresses of Volume
Location servers from the DNS using an AFSDB record.
This requires userspace support. /etc/request-key.conf must be configured to
invoke a helper for dns_resolver type keys with a subtype of "afsdb:" in the
description.

Separate out the DNS resolver key type from the CIFS filesystem into its own
module so that it can be made available for general use, including the AFS
filesystem module.
This facility makes it possible for the kernel to upcall to userspace to have
it issue DNS requests, package up the replies and present them to the kernel
in a useful form. The kernel is then able to cache the DNS replies as keys
can be retained in keyrings.
Resolver keys are of type "dns_resolver" and have a case-insensitive
description that is of the form "[<type>:]<domain_name>". The optional <type>
indicates the particular DNS lookup and packaging that's required. The
<domain_name> is the query to be made.
If <type> isn't given, a basic hostname to IP address lookup is made, and the
result is stored in the key in the form of a printable string consisting of a
comma-separated list of IPv4 and IPv6 addresses.
This key type is supported by userspace helpers driven from /sbin/request-key
and configured through /etc/request-key.conf. The cifs.upcall utility is
invoked for UNC path server name to IP address resolution.
The CIFS functionality is encapsulated by the dns_resolve_unc_to_ip() function,
which is used to resolve a UNC path to an IP address for CIFS filesystem. This
part remains in the CIFS module for now.
See the added Documentation/networking/dns_resolver.txt for more information.

It turns out that not all directory inodes with dentries on the
i_dentry list are unusable here. We only consider them unusable if they
are still hashed or if they have a root dentry attached.
Full disclosure -- this check is inherently racy. There's nothing that
stops someone from slapping a new dentry onto this inode just after
this check, or hashing an existing one that's already attached. So,
this is really a "best effort" thing to work around misbehaving servers.

Make cifs_convert_address() take a const src pointer and a length so that all
the strlen() calls in their can be cut out and to make it unnecessary to modify
the src string.
Also return the data length from dns_resolve_server_name_to_ip() so that a
strlen() can be cut out of cifs_compose_mount_options() too.

Subject: [PATCH 1/2] cifs: show features compiled in as part of DebugData
This patch adds the features that are compiled in to the CIFS debugging data
as shown below:
$cat /proc/fs/cifs/DebugData
Display Internal CIFS Data Structures for Debugging
---------------------------------------------------
CIFS Version 1.64
Features: dfs fscache posix spnego xattr
Active VFS Requests: 0
...
This patch provides a definitive way to tell what features are currently
enabled in the running kernel. This could also help debugging.
