nfsd: protect clid and verifier generation with client_lock
The clid counter is a global counter currently. Move it to be a per-net
property so that it can be properly protected by the nn->client_lock
instead of relying on the client_mutex.
The verifier generator is also potentially racy if there are two
simultaneous callers. Generate the verifier when we generate the clid
value, so it's also created under the client_lock. With this, there's
no need to keep two counters as they'd always be in sync anyway, so
just use the clientid_counter for both.
As Trond points out, what would be best is to eventually move this
code to use IDR instead of the hash tables. That would also help ensure
uniqueness, but that's probably best done as a separate project.

nfsd: add a new /proc/fs/nfsd/max_connections file
Currently, the maximum number of connections that nfsd will allow
is based on the number of threads spawned. While this is fine for a
default, there really isn't a clear relationship between the two.
The number of threads corresponds to the number of concurrent requests
that we want to allow the server to process at any given time. The
connection limit corresponds to the maximum number of clients that we
want to allow the server to handle. These are two entirely different
quantities.
Break the dependency on increasing threads in order to allow for more
connections, by adding a new per-net parameter that can be set to a
non-zero value. The default is still to base it on the number of threads,
so there should be no behavior change for anyone who doesn't use it.

nfsd: make NFSd service structure allocated per net
This patch makes main step in NFSd containerisation.
There could be different approaches to how to make NFSd able to handle
incoming RPC request from different network namespaces. The two main
options are:
1) Share NFSd kthreads betwween all network namespaces.
2) Create separated pool of threads for each namespace.
While first approach looks more flexible, second one is simpler and
non-racy. This patch implements the second option.
To make it possible to allocate separate pools of threads, we have to
make it possible to allocate separate NFSd service structures per net.
