My original intent for ofpbufs initialized with ofpbuf_use_stack() was that
the caller was providing enough space on the stack for the common case,
with dynamic allocation as a fallback. But in practice, none of the
clients actually do this. Instead, all of them actually know that the
stack-allocated buffer is big enough and, since they don't want to bother
with having to call ofpbuf_delete(), they instead assert that the buffer
wasn't reallocated.
Since this is a bit of a pain, this commit changes the semantics of
ofpbuf_use_stack() to be that the stack-allocated buffer cannot be
reallocated at all. This is more convenient for the existing clients.
This new function is a simple helper that creates a new ofpbuf with some
initial contents plus a caller-specified amount of headroom.
This will be used in upcoming commits.

This new function is useful in a situation where a small stack-allocated
buffer is usually appropriate but occasionally it must be expanded.

ovs_queue doesn't seem very useful; it's just a singly-linked list. It's
more generally useful to use a general-purpose "struct list" for lists of
packets, so this commit adds such a member to "struct ofpbuf" and shifts
the existing users to use it.
