Decode the implementation ID and display in nfsd/clients/#/info. It may
be help identify the client. It won't be used otherwise.
(When this went into the protocol, I thought the implementation ID would
be a slippery slope towards implementation-specific workarounds as with
the http user-agent. But I guess I was wrong, the risk seems pretty low
now.)

NFSv4 clients are automatically expired and all their locks removed if
they don't contact the server for a certain amount of time (the lease
period, 90 seconds by default).
There can still be situations where that's not enough, so allow
userspace to force expiry by writing "expire\n" to the new
nfsd/client/#/ctl file.
(The generic "ctl" name is because I expect we may want to allow other
operations on clients in the future.)
The write will not return until the client is expired and all of its
locks and other state removed.
The fault injection code also provides a way of expiring clients, but it
fails if there are any in-progress RPC's referencing the client. Also,
its method of selecting a client to expire is a little more
primitive--it uses an IP address, which can't always uniquely specify an
NFSv4 client.

Add a nfsd/clients/#/opens file to list some information about all the
opens held by the given client, including open modes, device numbers,
inode numbers, and open owners.
Open owners are totally opaque but seem to sometimes have some useful
ascii strings included, so passing through printable ascii characters
and escaping the rest seems useful while still being machine-readable.

I'm exposing some information about NFS clients in pseudofiles. I
expect to eventually have simple tools to help read those pseudofiles.
But it's also helpful if the raw files are human-readable to the extent
possible. It aids debugging and makes them usable on systems that don't
have the latest nfs-utils.
A minor challenge there is opaque client-generated protocol objects like
state owners and client identifiers. Some clients generate those to
include handy information in plain ascii. But they may also include
arbitrary byte sequences.
I think the simplest approach is to limit to isprint(c) && isascii(c)
and escape everything else.
That means you can just cat the file and get something that looks OK.
Also, I'm trying to keep these files legal YAML, which requires them to
UTF-8, and this is a simple way to guarantee that.

After commit 95582b008388 "vfs: change inode times to use struct
timespec64" there are spots in the NFSv4 decoding where we decode the
protocol into a struct timeval and then convert that into a timeval64.
That's unnecesary in the NFSv4 case since the on-the-wire protocol also
uses 64-bit values. So just fix up our code to use timeval64 everywhere.

Do as the NLM client: allocate and track a struct nlm_lockowner for use as
the fl_owner for locks created by the NLM sever. This allows us to keep
the svid within this structure for matching locks, and will allow us to
track the pid of lockd in a future patch. It should also allow easier
reference of the nlm_host in conflicting locks, and simplify lock hashing
and comparison.

The nfsd duplicate reply cache should not be shared between network

Since commit 10a68cdf10 (nfsd: fix performance-limiting session
calculation) (Linux 5.1-rc1 and 4.19.31), shares from NFS servers with
1 TB of memory cannot be mounted anymore. The mount just hangs on the
client.
The gist of commit 10a68cdf10 is the change below.
-avail = clamp_t(int, avail, slotsize, avail/3);
+avail = clamp_t(int, avail, slotsize, total_avail/3);
Here are the macros.
#define min_t(type, x, y) __careful_cmp((type)(x), (type)(y), <)
#define clamp_t(type, val, lo, hi) min_t(type, max_t(type, val, lo), hi)
`total_avail` is 8,434,659,328 on the 1 TB machine. `clamp_t()` casts
the values to `int`, which for 32-bit integers can only hold values
−2,147,483,648 (−2^31) through 2,147,483,647 (2^31 − 1).
`avail` (in the function signature) is just 65536, so that no overflow
was happening. Before the commit the assignment would result in 21845,
and `num = 4`.
When using `total_avail`, it is causing the assignment to be
18446744072226137429 (printed as %lu), and `num` is then 4164608182.
My next guess is, that `nfsd_drc_mem_used` is then exceeded, and the
server thinks there is no memory available any more for this client.
Updating the arguments of `clamp_t()` and `min_t()` to `unsigned long`
fixes the issue.
Now, `avail = 65536` (before commit 10a68cdf10 `avail = 21845`), but
`num = 4` remains the same.
