h_FindClient_r checks the connection rock for a client object twice.
First it sees if we already have a client object, and if we don't, we
effectively create one (or find a suitable one). Then we check again,
to see if someone else set the rock while we were creating a client
structure.
Currently, the first check checks if client->host->hostFlags has
HOSTDELETED set, but the second check does not. So, if the host
associated with the client has been deleted by someone else, currently
we will unnecessarily log a "stillborn client" message, and we will
continue to use the deleted host. If the host continues to be held by
someone, we will run into the same situation repeatedly on future
requests until all of the host references go away.
To fix this, also ignore HOSTDELETED clients when performing the
stillborn race check.

vos offline is supposed to bring a volume back online from "busy"
status before exiting, as volumes should not be in "busy" status for
extended periods of time. This was being enforced by required that
-sleep be specified; however, -sleep only results in the volume being
brought back online if a non-zero sleep time was specified. So, make
sure the volume is brought back online if -busy was specified.

On Linux kernels that support keyrings, when we setpag we try to add
the PAG to the session keyring and to the supplemental group list.
Currently, if we fail to add the PAG to the keyring (which may happen
due to key quotas, or possibly other reasons), we return failure but
the group list is still modified with the new PAG in it.
Therefore, if the keyring-based approach fails, the new PAG may still
be in use, but there are no keyring keys associated with that PAG, so
the PAG may never get destroyed. This can cause a large number of PAGs
to accumulate over time, causing performance problems.
So, change this so that, in the event that keyring installation fails,
we revert the group list back to what it was before we touched it.
Also mark all unixusers with the new PAG as expired, in case one got
created during processing. Thus, the new PAG never gets used.

We can end up discarding a receive queue that's been soft acked,
effectively taking back soft acks we sent. Whilst the RX
documentation says that a client can drop soft acked packets at
will, our RX implementation assumes that if the final packet in
a call has been soft acked, we won't clear the queue. If a client
clears the queue in this situation, the call will hang.
What *should* happen is that we should take necessary locks,
confirm that we have not soft-acked all of the packets in a flow,
and then discard, or, if we're just going to discard, error the
call.

The ptserver database building scripts would check to see if the server
was running from a bosserver with the noauth flag set before performing
a database rebuild.
This means that you can't start ptserver normally, and then configure
the database using pts -localauth, which is the preferred method for
configuring new cells.
Remove the check for noauth. This is slightly risky, as it means that a
corrupt database could be completely erased upon restart. However, we
already check that the dbheader (65k) is entirely blank - which will
protect us against any single page corruption errors.

unsafe to do anything after InflightLibraryEvent has been signalled.
