This CL fixes four cases of what I believe are undefined behavior:
- In vhost where the original code allocates a Vec<u8> with 1-byte
alignment and casts the Vec's data pointer to a &mut vhost_memory
which is required to be 8-byte aligned. Underaligned references of
type &T or &mut T are always undefined behavior in Rust.
- Same pattern in x86_64.
- Same pattern in plugin::vcpu.
- Code in crosvm_plugin that dereferences a potentially underaligned
pointer. This is always undefined behavior in Rust.
