Add an option to wait_for_read_send(), so that the request, upon
calling back, report whether the socket actually contains data
or is in EOF/error state. EOF is signalled via the EPIPE error.
This is useful for clients which do not expect data to arrive but
wait for readability to detect a closed socket (i.e. they do not
intend to actually read the socket when it's readable). Actual data
arrival would indicate a bug in this case, so the check can
be used to print an error message.

This patch allows for early cleanup of client connections if the client
has given up.
Before this patch, any received request would be processed, and then only
upon transmitting the result to the client would winbindd find out the
client is no longer with us, possibly leading to a situation where the
same client tries over and over and increases the number of client
connections.
This patch monitors the client socket for readability while the request
is being processed, and closes the client connection if the socket
becomes readable. The client is not supposed to be writing anything to
the socket while it is waiting, so readability means either that the client
has closed the connection, or that it has broken the protocol.

Note that the 60.ganesha RPC checks need to be identical to those in
the nfs-checks.d/ directory. This is because the NFS unit test
infrastructure checks output against what should be produced by the
checks in nfs-checks.d/. This is a minor issue, since one of the aims
of this work is to remove the need for a separate 60.ganesha.
In most cases configuration variable CTDB_NFS_DUMP_STUCK_THREADS is
now ignored. This is now handled by passing the desired number of
threads to the command specified in the service_debug_cmd variable in
a .check file.

Change status, nlockmgr, mountd, rquotad to be unhealthy after 6
rpcinfo check failures and do a verbose restart after every 2
failures. Change 60.ganesha for consistency, since 60.ganesha tests
are broken and depend on the consistency.
Apart from the consistency aspect, the check infrastructure will soon
be simplified so that it only allows the equivalent of "unhealthy" and
"verbose restart:b" actions.
Update tests to have a corresponding numbers of iterations. Run 1
extra iteration in most tests to check there are no unexpected
behaviour changes after the designated number of iterations completes.
