This patch changes the stp_port_get_role and removes
the stp_port_get_id, because stp/show has locked the
mutex before calling the stp_port_get_role, and
stp_port_get_id will not be used.

Currently dp-packet make use of ofpbuf for managing packet
buffers. That complicates ofpbuf, by making dp-packet
independent of ofpbuf both libraries can be optimized for
their own use case.
This avoids mapping operation between ofpbuf and dp_packet
in datapath upcalls.

Commit 0d1cee123a (stp: Fix bpdu tx problem in listening state)
makes ovs drop the stp bpdu packets if stp is not enabled on the
input port. However, when pif bridge is used and stp is enabled
on the integration bridge. The flow translation of stp bpdu
packets will go through a level of resubmission which changes
the input port to the corresponding peer port. Since, the
patch port on the pif bridge does not have stp enabled, the
flow translation will drop the bpdu packets.
This commit fixes the issue by making ovs forward stp bpdu packets
on stp-disabled port.

The restriction only allows to send bpdu in forwarding state in
compose_output_action__. But a port could send bpdu in listening
and learning state according to comments in lib/stp.h(State of
an STP port).
Until this commit, OVS did not send out BPDUs in listening and learning
states. But those two states are temporary, the stp port will be in
forwarding state and send out BPDUs eventually (In the default
configuration listening and learning states last 15+15 second). Therefore,
this bug increased convergence time but did not entirely break STP.

When debugging spanning tree, it's useful to have counters about how
many BPDUs have been sent and received. This commit keeps track of
these counters and stores them in a new "statistics" column of the Port
table.
Feature #8103
- Don't apply endian conversions to flags, which are 8 bits.
- Use #defines for default times for use outside library.
- Clarify our behavior when in STP_DISABLED state.
- Add "aux" member to STP port struct to be able to refer back to
the owning port.
- Define macros to print STP bridge and port ids.
- New helper function to get port id.
- New helper function to convert speed to cost.
- New functions to describe current role of port.
At one point, the OVS distribution contained an IEEE 802.1D Spanning
Tree Protocol (STP) library written by Ben Pfaff and based on the
802.1D-1998 reference code. It was never integrated into ovs-vswitchd,
so it was removed as part of commit ba18611 (Remove vestigial support
for Spanning Tree Protocol.)
This commit reintroduces the library, cleans up a few spots, and makes
it build cleanly against new code. A future commit will have
ovs-vswitchd use this library.
Open vSwitch has never properly supported IEEE 802.1D Spanning Tree
Protocol (STP), but it has various bits and pieces that claim to support
it. This commit deletes them, to reduce the amount of dead code in the
tree. We can always reintroduce it later if it proves to be a good idea.
Bug #1175.
