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.

./configure accepts --enable-ndebug option. Make ovs_assert() honor
it, and make sure all test programs disable it.
The order of include files in test programs is also made uniform:
1. #include <config.h>
2. #undef NDEBUG
3. Include file of the test subject (to make sure it itself has
sufficient include directives).
4. System includes in alphapetical order.
5. OVS includes in aplhapetical order.

To prevent warnings such as "Not all control paths return a value",
we should define NO_RETURN for MSVC.
Currently for gcc, we add NO_RETURN at the end of function declaration.
But for MSVC, "__declspec(noreturn)" is needed at the beginning of function
declaration. So this commit moves NO_RETURN to the beginning of the function
declaration as it works with gcc and clang too.

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.
