rust: declare self as qemu_api for proc-macros

Fix an outstanding TODO.

Declaring `extern crate self as qemu_api` allows use of `qemu_api`
within the qemu_api crate; this allows the Wrapper derive macro and

i386/tcg/svm: fix incorrect canonicalization

For all 32-bit systems and 64-bit Windows systems, "long" is 4 bytes long.
Due to using "long" for a linear address, svm_canonicalization would
set all high bits to 1 when (assuming 48-bit linear address) the segment
base is bigger than 0x7FFF.

This fixes booting guests under TCG when the guest IDT and GDT bases are
above 0x7FFF, thereby resulting in incorrect bases. When an interrupt
arrives, it would trigger a #PF exception; the #PF would trigger again,
resulting in a #DF exception; the #PF would trigger for the third time,
resulting in triple-fault, and eventually causes a shutdown VM-Exit to
the hypervisor right after guest boot.

x86/loader: Don't update kernel header for CoCo VMs

Update the header makes it different from the original kernel that user
provides via "-kernel", which leads to a different hash and breaks the
attestation, e.g., for TDX.

We already skip it for SEV VMs. Instead of adding another check of
is_tdx_vm() to cover the TDX case, check machine->cgs to cover all the

tests/functional: Mark main in QemuBaseTest class as a static method

The main() method in the QemuBaseTest class has no parameters but is
defined as a regular method. Currently, this does not cause any issues
because in the functional tests main() is always called directly from
QemuBaseTest (never from instances), but the way this method is defined
makes its signature wrong, implying a 'self'. Hence, it's best practice
to define such a method as a static method, so decorate it with
@staticmethod.
