FIXES 25869

acl_CheckRights() was generating core dumps because the client's prlist
was being invalidated by h_TossStuff_r() as part of freeing the associated
host.  This patch fixes the problem in probably redundant ways.
A missing hold on the host is now obtained.  refCounts on the client
are now preserved as part of GetClient()/PutClient().  Read/Write locks
are now obtained on the client when accessing/manipulating the prlist.

This patch adds the client parameter to GetVolumePackage() and
PutVolumePackage() and adds the new function PutClient().

This patch removes the need for the client X had conn Y stolen by X messages.
This is replaced by "deleted client X already had conn Y stolen by X.  If
we see this there is definitely a logic problem as the client should not
be deleted at this point.  We a no longer allowing the race condition that
would have resulted in the original message.

In addition, this patch fixes a problem with UAEs caused by the
inappropriate translation of VICE error into UAEs when there is overlap
between VICE error values and those in sys/errno.h.
