During the transition to the configuration database, not all code from

which removes port configuration based on RTNL notifications of port
removal was not updated. This commit brings that code back.

reconnect: Fix repeated RECONNECT_CONNECT that was confusing JSON-RPC.
reconnect_run() returns RECONNECT_CONNECT to tell the client that it should
start a new connection. The client is then supposed to call
reconnect_connecting() to tell the FSM that it has begun a connection
attempt. However, even after reconnect_connecting() was called,
reconnect_run() continued to return RECONNECT_CONNECT on each call until
the connection succeeded or failed. This confused the jsonrpc_session
client, which expected that it would get a 0 return value from
reconnect_run() while the connection attempt was in progress. Connections
that required multiple trips through the main poll loop, e.g. for SSL
negotiation, would often get cut off to start a second connection attempt.
This commit change reconnect_run() to return RECONNECT_CONNECT only until
the client tells it that a connection is in progress, which fixes the
problem. This change entails a change to the internal details of the
reconnect FSM, so this commit also updates the reconnect tests to match.

daemon: Allow daemon child process to report success or failure to parent.
There are conflicting pressures in startup of a daemon process:
* The parent process should exit with an error code if the daemon
cannot start up successfully.
* Some startup actions must be performed in the child process, not in
the parent. The most obvious of these are file locking, since
child processes do not inherit locks, and anything that requires
knowing the child process's PID (e.g. unixctl sockets).
Until now, this conflict has usually been handled by giving up part of the
first property, i.e. in some cases the parent process would exit
successfully and the child immediately afterward exit with a failure code.
This commit introduces a better approach, by allowing daemons to perform
startup work in the child and only then signal the parent that they have
successfully started. If the child instead exits without signaling
success, the parent passes this exit code along to its own parent.

xenserver: Actually destroy VIFs by using ovs-vsctl
When VIFs were destroyed, they were not actually being deleted in the
config database. This commit makes the appropriate ovs-vsctl commands
in the 'vif' script to accomplish that.

ovs-vsctl: Set timeout to a default value of five seconds
In general, we don't want ovs-vsctl to wait forever to connect to the
database, as ovs-vsctl is used extensively in init scripts and the
system will not boot. Use a default value of five seconds as a
stop-gap. Eventually, we'll switch to a model of connection attempts,
since using time-based approach is kind of a hack.

xenserver: Cleanup xs-network-uuids and xs-network-names usage
Switch xs-network-uuids delimiter to a semicolon to match the one used
by xs-network-uuids. Also, fix pluralization of xs-network-uuids in
vswitch IDL description of the "Bridge" table.
Add description of xs-network-names to vswitch IDL description.

vswitchd: Do not choose generated MAC address for local port.
ovs-vswitchd needs to choose a sensible MAC address for the local port of
a bridge. Until now, the algorithm has ignored certain interfaces, in
particular internal interfaces and those with the MAC addresses that
indicate that they are probably Xen VIFs. The goal is to choose a physical
interface's MAC address because this is more stable and more likely to
be meaningful to the outside world. Stability, in turn, is important
because the MAC address of the local port is used as the default datapath
ID for OpenFlow connections.
This existing algorithm was too specialized to work well with the new
kinds of ports that we have been introducing in OVS. In particular,
GRE ports could be chosen as the MAC address. This commit changes the
algorithm for choosing the local port MAC address. Now it ignores any
interface that has the "local" bit set in its MAC address, which
catches GRE ports. The new rule also catches the VIF and internal
port cases, so this commit also deletes those special cases.
This commit deleted the only user of eth_addr_is_vif(), so it deletes
that function also.
Jesse Gross suggested this revised heuristic.

socket-util: Clarify EAGAIN error code for make_unix_socket().
make_unix_socket() can return EAGAIN in rare circumstances, e.g. when the
server's socket listen queue is full. A lot of OVS callers interpret
EAGAIN as a "try again" error code, but in this case it means that the
attempt to create the socket failed. So munge EAGAIN into another error
code to prevent that misinterpretation.
