stream-ssl: Change "bootstrap race" log message from ERR to INFO.

This situation can and will happen, and we handle it successfully, so it's
not an error.

Bug #12922.

cfm: Report opup as undefined if not in extended mode.

The cfm_get_opup() function's result doesn't make sense when CFM is
not configured in extended mode.  This patch makes it report -1 in
this case.  Future patches will rely on this behavior.

cfm: Expose remote CFM opstate in the database.

A controller may want to know the remote CFM opstate of a given CFM
enabled interface.  This patch makes this data available in the
database.

tests: Add delay in NetFlow unit tests before killing processes.

At the end of the NetFlow unit tests we warp time to force any
remaining flows to expire and then immediately kill OVS and the
collector.  However, this creates a race where sometimes these
processes are killed before the last records are sent or collected.
It's possible to force OVS to go through the run loop one last time
before exiting but it's harder to enforce that the collector receives
the packet.  This simply avoids the problem by adding a 1 second delay
before killing the processes, which should be more than enough time.

Correct number of bytes to allocated for slaves in bundle action.

The size of each slave is a uint16_t.  This means that each slave needs 2 bytes
at the end of nx_action_bundle.  Earlier, the size of each slave was not being
factored in when allocating space.  This commit corrects that by allocating 2
bytes for each slave when calculating the total number of bytes to be allocated
at the end of nx_action_bundle.

bridge: Write certain statistics to the database instantly.

Traditionally the bridge has written interface and port statistics
to the database in a rate limited fashion.  This makes a lot of
sense for statistics which are either constantly changing, or are
expensive to collect.  However, some statistics were rate limited
which have neither of these properties.  Furthermore some of these
statistics (most notably carrier) could be very useful to a
controller if updated promptly.

netdev: Map to OpenFlow port for flow lookup

In the flow hash special ports are stored using OpenFlow constants.
For example the "local port" is stored as 0xfffe (OFPP_LOCAL).

ofproto-dpif: Avoid searching all subfacets when creating first in a facet.

When we create the first subfacet within a facet, we know that there
cannot be an existing subfacet with the same key, so we can skip the search
through the ofproto's table of subfacets.

This is a small optimization, but it should not affect the flow setup rate
in most benchmarks, because in the stressful situations that benchmarks
create, OVS does not set up flows.

ofproto-dpif: Make sure one-packet flows have zero duration.

A Nicira internal build recently failed the "ofproto-dpif - NetFlow flow
expiration" test because of the following difference in output:

     header: v5, seq 0, engine 2,1
    -rec: [...], 1 pkts, 60 bytes, ICMP 8:0, time <moment>
    +rec: [...], 1 pkts, 60 bytes, ICMP 8:0, time <range>

Looking at the actual output, it is:
    rec: 192.168.0.1 > 192.168.0.2, if 1 > 65535, 1 pkts, 60 bytes,
    ICMP 8:0, time 8...9

That is, a one-packet flow was shown to have more than a momentary
duration, which doesn't make sense.

This commit fixes the problem by making sure that creating a facet and then
its initial subfacet only checks the current time once.
