[0/8] Oxenstored live update fixes

Message

Andrew Cooper Nov. 22, 2022, 3:20 p.m. UTC

First set of Ocaml fixes, cleaned up from series posted previously.

Patch 1 fixes a logical error introduced in the xenstore live update support.

Patches 2-5 fix oxenstored to keep /dev/xen/evtchn open across live update.

Patches 6-8 fix various issues with diagnostics.

All previous feedback applied, but I've started this series again to avoid
confusion.
