Make TCP and UDP svc_sock transports, and register them
with the svc transport core.
A transport type (svc_sock) has an svc_xprt as its first member,
and calls svc_xprt_init to initialize this field.

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.

Support for binary sysctls is being deprecated in 2.6.24. Since there
are no applications using the NFS/RDMA client's binary sysctls, it
makes sense to remove them. The patch below does this while leaving
the /proc/sys interface unchanged.
Please consider this for 2.6.24.

This implements the configuration and building of the core transport
switch implementation of the rpcrdma transport. Stubs are provided for
the rpcrdma protocol handling, and the infiniband/iwarp verbs interface.
These are provided in following patches.

Introduce a replacement for the in-kernel portmapper client that supports
all 3 versions of the rpcbind protocol. This code is not used yet.
Original code by Groupe Bull updated for the latest kernel, with multiple
bug fixes.
Note that rpcb_clnt.c does not yet support registering via versions 3 and
4 of the rpcbind protocol. That is planned for a later patch.

Select an RPC client source port between 650 and 1023 instead of between
1 and 800. The old range conflicts with a number of network services.
Provide sysctls to allow admins to select a different port range.
Note that this doesn't affect user-level RPC library behavior, which
still uses 1 to 800.
Based on a suggestion by Olaf Kirch <okir@suse.de>.
Test-plan:
Repeated mount and unmount. Destructive testing. Idle timeouts.

Introduce block header comments and a function naming convention to the
socket transport implementation. Provide a debug setting for transports
that is separate from RPCDBG_XPRT. Eliminate xprt_default_timeout().
Provide block comments for exposed interfaces in xprt.c, and eliminate
the useless obvious comments.
Convert printk's to dprintk's.

Compile kernel with CONFIG_NFS enabled.

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!
