Paolo Bonzini ad523bca56 iov: avoid memcpy for "simple" iov_from_buf/iov_to_buf ... memcpy can take a large amount of time for small reads and writes. For virtio it is a common case that the first iovec can satisfy the whole read or write. In that case, and if bytes is a constant to avoid excessive growth of code, inline the first iteration into the caller.
