Default to not performing the early-boot memory tests when we detect we
are booting inside a VM. There are three reasons to disable this:
o It causes the VM host to believe that all the tested pages or RAM are
in use. This in turn may force the host to page out pages of RAM
belonging to other VMs, or otherwise cause problems with fair resource
sharing on the VM cluster.
o It adds significant time to the boot process (around 1 second/Gig in
testing)
o It is unnecessary - the host should have already verified that the
memory is functional etc.
Note that this simply changes the default when in a VM - it can still be
overridden using the hw.memtest.tests tunable.

The code in tcp_input() already safely handled this case. It can happen
due to delayed ACKs along with a remote sender that sends data beyond

many BIOSes are inconsistent/broken and that settings programmed into BARs

jhb@ spotted that nfscl_getstateid() might modify credentials when
called from nfsrpc_read() for the case where p != NULL, whereas
nfsrpc_read() only did a crdup() to get new credentials for p == NULL.

jwd@ reported a problem via email where the old NFS client would
get a reply of EEXIST from an NFS server when a Mkdir RPC was retried,
for an NFS over UDP mount.
Upon investigation, it was found that the client was retransmitting
the Mkdir RPC request over UDP, but with a different xid. As such,
the retransmitted message would miss the Duplicate Request Cache
in the server, causing it to reply EEXIST. The kernel client side
UDP rpc code has two timers. The first one causes a retransmit using
the same xid and socket and was set to a fixed value of 3seconds.
(The default can be overridden via CLSET_RETRY_TIMEOUT.)
The second one creates a new socket and xid and should be larger
than the first. However, both NFS clients were setting the second
timer to nm_timeo ("timeout=<value>" mount argument), which defaulted to
1second, so the first timer would never time out.
This patch fixes both NFS clients so that they set the first timer
using nm_timeo and makes the second timer larger than the first one.
