=== Add support for SCM_CREDENTIALS / SCM_PIDFD and friends ===
'''Summary:''' Support for SCM_CREDENTIALS / SCM_PIDFD
SCM_CREDENTIALS and SCM_PIDFD are types of SCM (Socket-level Control Messages). They play a crucial role
in systemd and many other user space applications. This project is about adding support for these
SCMs to be properly saved and restored back with CRIU. There is an existing code in OpenVZ CRIU fork,
see [1] and [2]. Goal would be first of all to properly port this code, cover with extensive tests and
ensure that SCM_PIDFD / SO_PEERPIDFD are handled correctly. Also we expect to cover things like
SO_PASSRIGHTS and SO_PASSPIDFD.
There is some extra source of complexity here pidfds can be "stale" (see PIDFD_STALE in Linux kernel)
and we need to ensure that we properly cover those cases.
