When the RSTP implementation sent BPDUs, it failed to initialize some of
their bytes. None of the code initialized an array of 7 padding bytes, and
some of it also failed to initialize the version1_length field. In
addition, the padding bytes confused some implementations that did not
correctly ignore extra bytes.
This commit fixes both problems, by removing the padding bytes and
initializing every byte in outgoing messages.

This patch is useful to debug rstp subsystem and log the
port name instead of port number. This patch will also
be used to display rstp info for next patches.

To easily allow both in- and out-of-tree building of the Python
wrapper for the OVS JSON parser (e.g. w/ pip), move json.h to
include/openvswitch. This also requires moving lib/{hmap,shash}.h.
Both hmap.h and shash.h were #include-ing "util.h" even though the
headers themselves did not use anything from there, but rather from
include/openvswitch/util.h. Fixing that required including util.h
in several C files mostly due to OVS_NOT_REACHED and things like
xmalloc.

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.

All MAC addresses previously learned on a Root Port can be moved to an
Alternate Port that becomes the new Root Port; i.e., Dynamic Filtering
Entries for those addresses may be modified to show the new Root Port as
their source, reducing the need to flood frames when recovering from
some component failures.

'rstp-admin-port-state' is the Administrative Bridge Port state
variable defined in the 802.1D-2004 standard. It can be set to
include or exclude a port from the active topology by management
(section 7.4).
operPointToPointMAC and 'rstp-admin-p2p-mac' are a pair of parameters
that permit inspection of, and control over, the administrative and
operational state of the point-to-point status of the MAC entity by
the MAC Relay Entity. adminPointToPointMAC can be set by management
and its value is reflected on operPointToPointMAC.

Current code expects there to be a single thread that is responsible
for creating rstp and creating and deleting rstp_port objects. rstp
objects are also deleted from other threads, as managed by reference
counting.
rstp port objects are not reference counted, which means that
references to rstp ports may only be held while holding the rstp
mutex, or by the thread that creates and deletes them.
This patch adds reference counting to RSTP ports, which allows ports
to be passed from ofproto-dpif to ofproto-dpif-xlate without using the
RSTP port number. This simplifies RSTP port reconfiguration, as the
port need not be resynchronized with xlate if just the port number
changes. This also avoids lookups on the processing of RSTP BPDUs.
This patch also:
1. Exposes the rstp mutex so that related thread safety annotations
can be used also within rstp-state-machines.c.
2. Internal variants of most setter an getter functions are defined,
suffixed with two underscores. These are annotated to be callable
only when the mutex is held.
3. Port setters were only called in a specific pattern. The new external
port setter combines them in a single rspt_port_set() function.
