Add loopback port to l2gre vport.

loci: remove *_new_from_message

These functions were never used. How would you know what type of message it was
without parsing it first? The test is changed to use
of_object_new_from_message, which is what actual clients use.
loci: factor out of_object_attach

This code was duplicated by bind and list operations, and will be used for
match deserialization..
loci: remove a malloc/free from parsing of_match_t

The code was allocating an of_wire_buffer_t on the heap (through some
indirection) and then immediately freeing it. We can just use the parent
object's wire buffer instead.

loci: remove minimum wire buffer allocation size

This hasn't been useful since writable wire buffers were changed to be
allocated at maximum size. This code was causing excessive memory usage in
Indigo when storing the instruction list, which is often only around 16 bytes.
Removing this code saves us 17% memory usage and increases flow-add performance
by 9%.

messages were using enum ofp_flow_mod_flags.
