name this particular macro.

Between musl and glibc there is a difference in the signature of the

after testing the build briefly, it seems upstream tianocore EDK2 works fine,
no need for the separate cloud-hypervisor edk2 repo.

Remove from the documentation and API definition but continue support
using the field (with a deprecation warning.)

Since the refactoring of the vm-migration crate broke the backward
compatibility, we must disable the live upgrade tests until next
release.

This simplifies the Snapshot creation as we expect a SnapshotData to be
provided most of the time.

The information about the identifier related to a Snapshot is only
relevant from the BTreeMap perspective, which is why we can get rid of
the duplicated identifier in every Snapshot structure.

There's no reason to carry a HashMap of SnapshotDataSection per
Snapshot. And given we now provide at most one SnapshotDataSection per
Snapshot, there's no need to keep the id part of the SnapshotDataSection
structure.

Without breaking the former way of declaring them. This is simply based
on the presence of the GUID TDX Metadata offset. If not present, we
consider the firmware is quite old and therefore we fallback onto the
previous way to expose memory resources.

The preferred way of retrieving the offset where to find the TDVF
descriptor structure is by going through a table of GUIDs that can be
found at a specific offset in the firmware file. If the expected GUIDs
can't be found, we can fallback onto the former way, which is to read
directly the value at a specific offset in the file.
This patch implements the new mechanism without breaking compatibility
for older firmwares as it keeps supporting the previous mechanism.
As a reference, here is the documentation from the EDK2 code, and
particularly from the OvmfPkg/ResetVector/Ia16/ResetVectorVtf0.asm file:
```
GUIDed structure. To traverse this you should first verify the
presence of the table footer guid
(96b582de-1fb2-45f7-baea-a366c55a082d) at 0xffffffd0. If that
is found, the two bytes at 0xffffffce are the entire table length.
The table is composed of structures with the form:
Data (arbitrary bytes identified by guid)
length from start of data to end of guid (2 bytes)
guid (16 bytes)
so work back from the footer using the length to traverse until you
either find the guid you're looking for or run off the beginning of
the table.

The datatype used for the ioctl() C library call is different between it
and the glibc toolchains. The easiest solution is to have the compiler
type cast to type of the parameter.
