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.
This commit also modifies the daemons that can usefully take advantage of

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.

ovsdb-idl: Fix row insertion and deletion behavior.
When the IDL was used to insert a row, but all of the new row's columns
were left at the default values, then the IDL would not insert the row at
all.
When the IDL was used to delete one or more rows, and the transaction did
not include any update or insertion operations, the transaction was dropped
entirely.
This commit fixes these two bugs. It needs a regression test, but this
commit does not add one.

xenserver: Have brctl wrapper use config DB instead of config file
This is a first cut and is likely buggy. VLANs have not been tested.

xenserver: Fixes related to creating config DB in RPM spec file
Some programs require a "Open_vSwitch" table to exist in the
configuration DB. This change adds that table when a new DB is created.
Also, don't try to create the DB unless it doesn't exist.

ovs-brcompatd: Remove references to locking config file
With the config DB, it is no longer necessary to lock the config file.
This removes references to the need for that.

With ovs-vswitchd using the config DB, it is no longer necessary to tell
it to reload its configuration file. This removes references to the
need for reloading.
It also cleans up some messages placed on the console during boot up.

xensource: Add kluge to make interface-reconfigure work better.
This change makes xsconsole able to reconfigure the management interface
on some XenServer hosts. It's not clear why it is needed--apparently
xapi is creating the bridge behind our back.

This makes debugging errors on XenServer much simpler, since many uses of
ovs-vsctl direct stderr to /dev/null.

xenserver: Make basic VM networking work.
Tested by starting and stopping a VM that has a single VIF and verifying

xenserver: Make basic interface-reconfigure calls work.
Now a XenServer can boot OK with the database at least in simple cases.
interface-reconfigure is slow because there is a 5-second sleep in place of
a proper way to wait for vswitchd reconfiguration to complete.
