[v8,0/3] Initial support for SPDM Responders

Message

The Security Protocol and Data Model (SPDM) Specification defines
messages, data objects, and sequences for performing message exchanges
over a variety of transport and physical media.

SPDM currently supports PCIe DOE and MCTP transports, but it can be
extended to support others in the future. This series adds
support to QEMU to connect to an external SPDM instance.

SPDM support can be added to any QEMU device by exposing a
TCP socket to a SPDM server. The server can then implement the SPDM
decoding/encoding support, generally using libspdm [1].

This is similar to how the current TPM implementation works and means
that the heavy lifting of setting up certificate chains, capabilities,
measurements and complex crypto can be done outside QEMU by a well
supported and tested library.

This series implements socket support and exposes SPDM for a NVMe device.

v8:
 - Fixup i386 failures (thanks to Wilfred)
 - Passes CI on GitLab: https://gitlab.com/alistair23/qemu/-/tree/mainline/alistair/spdm-socket.next?ref_type=heads
v7:
 - Fixup checkpatch failures
 - Fixup test failures
 - Rename port name to be clearer
v6:
 - Add documentation to public functions
 - Rename socket variable to spdm_socket
 - Don't override errp
 - Correctly return false from nvme_init_pci() on error
v5:
 - Update MAINTAINERS
v4:
 - Rebase
v3:
 - Spelling fixes
 - Support for SPDM-Utils
v2:
 - Add cover letter
 - A few code fixes based on comments
