Make qemu_peek_buffer loop until it gets it's data
Make qemu_peek_buffer repeatedly call fill_buffer until it gets
all the data it requires, or until there is an error.
At the moment, qemu_peek_buffer will try one qemu_fill_buffer if there
isn't enough data waiting, however the kernel is entitled to return
just a few bytes, and still leave qemu_peek_buffer with less bytes
than it needed. I've seen this fail in a dev world, and I think it
could theoretically fail in the peeking of the subsection headers in
the current world.
Comment qemu_peek_byte to point out it's not guaranteed to work for
non-continuous peeks
