These both look good to me.

It's perhaps a little weird to shed the now-always-NULL src arguments
from packet_read() in the second one, since the underlying function we
wrap still allows them.  But it does make the callers a little simpler,
and I think if we added any new callers that I'd much rather see them
use the struct-oriented packet_reader interface instead. Which is really
why it we can get rid of this function in the first place; it's old callers
are all using that interface.

In the long run, I'd be quite happy if could get rid of all of the
non-packet_reader calls entirely, but that's a much bigger topic. This
is a nice incremental step in that direction.
