Introduce 'virt-what-cvm' program
The 'virt-what' program prints facts that reflect the hypervisor that
the guest is running under.
The new complementary 'virt-what-cvm' program prints facts that reflect
the confidential virtualization technology the guest is running under,
if any.
It is kept as a separate tool, rather than incorporating the facts into
'virt-what' output because it is considering a different aspect of the
virtualization. Furthermore there are specific security concerns around
the usage of facts reported by 'virt-what-cvm'.
The tool has been tested in a number of environments
* Azure confidential guest with AMD SEV-SNP (GA)
* Azure confidential guest with Intel TDX (technology preview)
* Fedora 37 QEMU/KVM guest with AMD SEV (GA)
* Fedora 37 QEMU/KVM guest with AMD SEV-ES (GA)

Add support for Alibaba cloud on aarch64
This assumes you are running RHEL or another tenant which supports
ACPI. It probably won't work for guests using device tree.
Also we assume that the hypervisor is KVM. Since the hypervisor
indicates that it is RHEL 7, this is very likely to be true, but hard
to prove since there is no CPUID on Arm.

alibaba-cloud: Make the test more robust
This test worked by trying to make an HTTP connection to a path under
100.100.100.200, which if successful would indicate that it's an
Alibaba cloud instance. We only try the connection if SM-BIOS
information indicates the hardware OEM is Alibaba.
However 'make check' would hang if 100.100.100.200 doesn't immediately
reject the connection. I found that GCE is such an environment where
connecting to this address would hang rather than reject. GCE does
not have Alibaba hardware of course, but when doing 'make check' we
fake dmidecode data.
Make the test more robust by only trying to connect when we know we're

Add QEMU/KVM detection for ACPI-boot ARM
Detect QEMU/KVM on ARM guests that have been boot with ACPI, i.e.
without device tree. When boot with ACPI SMBIOS is populated, so we
can use dmidecode.

Add ARM support
Currently only detects LKVM, QEMU/KVM, and Xen. Also only works if
the guest is booted with DT (which is the only way that currently
exists).

* Makefile.am: use '$?' instead of '$<'
$< in a non-inference rule is a GNU-make extension, which fails with

virt-what.in: make option processing portable
Replace linux-specific 'getopt' usage with manual option parsing.
Because the used option are version simple (help/version) and the only
additional option is undocumented (--test-root), it's easy remove the
'getopt' usage, and make this script portable to BSD systems.
