HP-UX patches

The general principle is to install the latest HP-required patch bundle for the OS version, currently required bundles exist for 11i v1 and 11i v2. Proper functioning of the SSH Tectia software also requires the latest HP recommended patches for libc, pthread and linker tools. In addition, some individual patches may be needed to fix specific problems. Such patches are mentioned separately.
