[PATCH v2 00/12] nbd: enable use of TLS on non-TCP transports and other TLS improvements

["Daniel P. Berrangé" <berrange@redhat.com>]

This series was principally motivated by a desire to enabl use of TLS
on non-TCP transports. For x509 certificates this means we need a way
to set the hostname to use for validation. This also lets us override
the hostname when connecting on a TCP transport that is tunnelled or
port-forwarded. It also unlocks the ability to use PSK (pre-shared
keys) with UNIX sockets which would always have worked, had it not
been blocked by explicit checks in NBD code.

NB, the first patch in this series is common with my corresponding
migration series for TLS

  https://lists.gnu.org/archive/html/qemu-devel/2022-03/msg00556.html

In v2:

  - Tweak the filter for qemu-nbd export list to expose export name
  - Add "since" tag to QAPI addition
  - Minor docs fixes
