bc6acb842f block: fix status value size 
As per VirtIO spec 1.2 section 5.2.6, the `status` field is a byte, not
u32. cloud-hypervisor writes an `u32` to guest memory, which
accidentally zeros out the following 3 bytes, and may corrupt guest OS

18340d9761 hypervisor: mshv: fine-grained control over translation flags 
The assertion that only code emulation requires GVA to GPA translation
is wrong.

Allow the caller of `translate` to pass in permission flags directly.

Provide a new method `read_memory_flags` so that we can add the EXECUTE

e7c7a304e8 virtio-devices: fix UB getting tty size 
TIOCGWINSZ modifies its argument, so it needs to mutably borrow it.
Unfortunately, ioctl()'s signature is not able to enforce this, and
the write happens in the kernel, so I don't think anything like miri,
valgrind, UBSan, etc. would have been able to catch this.

The UB passing an immutable reference caused resulted, for me, in
get_win_size() returning (0, 0) since LLVM commit
9a09c737a052 ("[BasicAA] Make isNotCapturedBeforeOrAt() check for
calls more precise (#69931)").

I've had a look through the other ioctl() calls in Cloud Hypervisor,
and I don't think any others have the same problem.
