Some applications would prefer that the controller only be enabled for
a subset of bridges. This commit introduces an alternative syntax for
the XAPI vSwitchController key to enable the specification of such a
configuration.
The implementation of the configuration is currently a hack. The
problem is that some bridges (especially internal bridges) are only
created when a VIF is added to them. This means that attempting to
set the controller on boot as we used to do won't work. Ideally we
would should hook the creation of the bridge and set the controller at
that time. However, in XenServer 5.5 I can't find an appropriate
place to hook to do so.
To meet immediate requirements, this commit hacks the startup-based
approach by spawning background processes that watch for the creation
of the bridge and set the controller when it becomes available. We'll
have to replace it with a better and more robust solution ASAP.

netdev-linux: Properly store netdev_dev pointer for RTNL callbacks.
We were storing a struct netdev_dev_linux ** instead of a
netdev_dev_linux * in the cache map. This prevented the cache
from being invalidated on changes such as link status.

netdev: Increase default ingress policing burst size
The default burst rate was 10Kb. This increases it to 1000kb, since
we were having problems getting traffic through at 10kb. A better value
probably exists between these two points, but that will require
additional experimentation.

idl: Gracefully handle destroying a transaction before receiving its reply.
If ovsdb_idl_txn_destroy() is called to destroy a transaction before its
reply has been received from the database server, then until now we would
drop the connection to the database when the reply actually arrived,
because we would have no record of that transaction ID any longer.
Notably, ovs-vswitchd does this: it "fires and forgets" database
transactions. (Really, it should not do that, but that's a bigger commit.)
This commit fixes the problem by not dropping the database connection in
such a case.
This fixes an observed problem such that sometimes ovs-vsctl took a long
time to complete, which was because ovs-vswitchd was dropping its
connection to the database and backing off.

netdev-linux: Don't close(0) when closing an ordinary netdev.
Calling close(0) at random points is bad. It means that the next call to
socket() or open() returns fd 0. Then the next time a netdev gets closed,
that socket or file fd gets closed too, and you end up with weird "Bad
file descriptor" errors.

fatal-signal: After fork, clear hooks instead of disabling them.
Until now, fatal_signal_fork() has simply disabled all the fatal signal
callback hooks. This worked fine, because a daemon process forked only
once and the parent didn't do much before it exited.
But upcoming commits will introduce a --monitor option, which requires
processes to fork multiple times. Sometimes the parent process will fork,
then run for a while, then fork again. It's not good to disable the
hooks in the child process in such a case, because that prevents e.g.
pidfiles from being removed at the child's exit.
So this commit changes the semantics of fatal_signal_fork() to just
clearing out hooks. After hooks are cleared, new hooks can be added and
will be executed on process termination in the usual way.
This commit also introduces a cancellation callback function so that a
canceled hook can free resources.

netdev-linux: Cleanup tap netdev.
TAP devices need to be treated slightly differently from other other
devices because they cannot be opened multiple times. Instead we
open them once and share the file descriptor. This means that if
the netdev is opened multiple times one reader can drain the buffers
of another. While this is a deviation from the normal convention,
it does not impact current or planned users.
In addition, this cleans up some confusion between the file
descriptor for tap devices versus other FD's.
