This new option allows the user to define a list of SGX EPC sections
attached to a specific NUMA node.

In order to uniquely identify each SGX EPC section, we introduce a
mandatory option `id` to the `--sgx-epc` parameter.

Enabling CONFIG_HYPERV in the Linux Kernel allows

The guest can see that SGX supports provisioning as it is exposed
through the CPUID. This patch enables the proper backing of this
feature by having the host open the provisioning device and enable
this capability through the hypervisor.

The cloud hypervisor tells the VM and the backend to support the PACKED_RING feature,
but it actually processes various variables according to the split ring logic, such
as last_avail_index. Eventually it will cause the following error (SPDK as an example):
vhost.c: 516:vhost_vq_packed_ring_enqueue: *ERROR*: descriptor has been used before
vhost_blk.c: 596:process_blk_task: *ERROR*: ====== Task 0x200113784640 req_idx 0 failed ======

This patch fixes a few things to support TDVF correctly.
The HOB memory resources must contain EFI_RESOURCE_ATTRIBUTE_ENCRYPTED
attribute.
Any section with a base address within the already allocated guest RAM
must not be allocated.
The list of TD_HOB memory resources should contain both TempMem and
TdHob sections as well.

If GICR_CTLR is restored before GICR_PROPBASER and GICR_PENDBASER,
the restoring of the latter registers will fail, as the LPI enable
bit is already set in GICR_CTLR. Therefore, in this commit, the
order of restoring GICR registers is changed.

This commit implements two helper functions `gicv3_its_attr_access`

ITS tables.

In current code, the ITS device fd of GICv3 will be lost after the
creation of GIC. This commit adds a new `its_device` field for the
`GicV3Its` struct, which will be useful to save the ITS device fd.
This fd will be used in restoring the ITS device.

The BAR calculation code was incorrect for calculating I/O BARs but also
has misleading comments (mixing bits and bytes, first and least
significant, etc).
This change adjusts the algorithm to more closely match the version
described in the PCI specification and takes advantage of Rust's binary
literals for ease of reading. Although this is slightly longer by
calculating the 64-bit and 32-bit paths separately I think this is
easier to read.

Previously the same function was used to both create and remove regions.
This worked on KVM because it uses size 0 to indicate removal.
MSHV has two calls -- one for creation and one for removal. It also
requires having the size field available because it is not slot based.
Split set_user_memory_region to {create/remove}_user_memory_region. For
KVM they still use set_user_memory_region underneath, but for MSHV they
map to different functions.
This fixes user memory region removal on MSHV.

The to-be-introduced MSHV rules don't need to contain KVM rules and vice
versa.
Put KVM constants into to a module. This avoids the warnings about
dead code in the future.

The TX rate limiter didn't correctly handle the `-EAGAIN` situation
where it should replenish the rate-limiter tokens. This patch simplifies
the TX rate-limiter code path by following the similar trade-off made in
the TX rate limiter, where we always let the `last` descriptor
go-through (even if it was over the rate limit. We simply stop
processing the oncoming `descriptors` if any.
Fixes: #2817

The output from getty ("login:") does not always appear. This can be
observed interactively when booting the VM. (Mashing return will bring
it up.) Instead of checking for that string to ensure the VM has booted
instead check for a message from systemd to say it has started the SSH
daemon.
