xprtrdma: add separate Kconfig options for NFSoRDMA client and server support
There are two entirely separate modules under xprtrdma/ and there's no
reason that enabling one should automatically enable the other. Add
config options for each one so they can be enabled/disabled separately.

SUNRPC: sunrpc should not explicitly depend on NFS config options

SUNRPC: Provide functions for managing universal addresses
Introduce a set of functions in the kernel's RPC implementation for
converting between a socket address and either a standard
presentation address string or an RPC universal address.
The universal address functions will be used to encode and decode
RPCB_FOO and NFSv4 SETCLIENTID arguments. The other functions are
part of a previous promise to deliver shared functions that can be
used by upper-layer protocols to display and manipulate IP
addresses.
The kernel's current address printf formatters were designed
specifically for kernel to user-space APIs that require a particular
string format for socket addresses, thus are somewhat limited for the
purposes of sunrpc.ko. The formatter for IPv6 addresses, %pI6, does
not support short-handing or scope IDs. Also, these printf formatters
are unique per address family, so a separate formatter string is
required for printing AF_INET and AF_INET6 addresses.

nfs41: New backchannel helper routines
This patch introduces support to setup the callback xprt on the client side.
It allocates/ destroys the preallocated memory structures used to process
backchannel requests.
At setup time, xprt_setup_backchannel() is invoked to allocate one or
more rpc_rqst structures and substructures. This ensures that they
are available when an RPC callback arrives. The rpc_rqst structures
are maintained in a linked list attached to the rpc_xprt structure.
We keep track of the number of allocations so that they can be correctly
removed when the channel is destroyed.
When an RPC callback arrives, xprt_alloc_bc_request() is invoked to
obtain a preallocated rpc_rqst structure. An rpc_xprt structure is
returned, and its RPC_BC_PREALLOC_IN_USE bit is set in
rpc_xprt->bc_flags. The structure is removed from the the list
since it is now in use, and it will be later added back when its
user is done with it.
After the RPC callback replies, the rpc_rqst structure is returned
by invoking xprt_free_bc_request(). This clears the
RPC_BC_PREALLOC_IN_USE bit and adds it back to the list, allowing it
to be reused by a subsequent RPC callback request.
To be consistent with the reception of RPC messages, the backchannel requests
should be placed into the 'struct rpc_rqst' rq_rcv_buf, which is then in turn
copied to the 'struct rpc_rqst' rq_private_buf.

SUNRPC: Add a generic RPC credential

svc: Add an svc transport class
The transport class (svc_xprt_class) represents a type of transport, e.g.
udp, tcp, rdma. A transport class has a unique name and a set of transport
operations kept in the svc_xprt_ops structure.
A transport class can be dynamically registered and unregisterd. The
svc_xprt_class represents the module that implements the transport
type and keeps reference counts on the module to avoid unloading while
there are active users.
The endpoint (svc_xprt) is a generic, transport independent endpoint that can
be used to send and receive data for an RPC service. It inherits it's
operations from the transport class.
A transport driver module registers and unregisters itself with svc sunrpc
by calling svc_reg_xprt_class, and svc_unreg_xprt_class respectively.

Note that rpcb_clnt.c does not yet support registering via versions 3 and

Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
