The webapp will check twice a day, when the network is connected, to see if
it can download a distributon upgrade file. If a newer version is found,
display an upgrade alert.
This will need the autobuilders to set UPGRADE_LOCATION to the url
it can be downloaded from when building git-annex. Only builds with that
set need automatic upgrade alerts.
Currently, the upgrade page just requests the user manually download
and upgrade it. But, all the info is provided to do automated upgrades
in the future.
Note that urls used will need to all be https.

This affected both the hourly NetWatcherFallback thread and the syncing
when network connection is detected.
It was a reversion of sorts, introduced in
8861e270be, when annex-ignore was changed to
not control git syncing. I forgot to make it check annex-sync at that
point.
This is so git remotes on servers without git-annex installed can be used
to keep clients' git repos in sync.
This is a behavior change, but since annex-sync can be set to disable
syncing with a remote, I think it's acceptable.
Converted several threads to run in the monad.
Added a lot of useful combinators for working with the monad.
Now the monad includes the name of the thread.
Some debugging messages are disabled pending converting other threads.
MountWatcher can't do this, because it uses the session dbus,
and won't have access to the new DBUS_SESSION_BUS_ADDRESS if a new session
is started.
Bumped dbus library version, FD leak in it is fixed.
Now when the dbus connection is dropped, it'll fall back to polling.
I could make it try to reconnect, but there's a FD leak in the dbus
library, so not yet.
Hooked up everything that needs to notify on pushes. Note that
syncNewRemote does not notify. This is probably ok, and I'd need to thread
more state through to make it do so.
This is only set up to support a single push notification method; I didn't
use a NotificationBroadcaster. Partly because I don't yet know what info
about pushes needs to be communicated, so my data types are only
preliminary.
Avoid trying to git push/pull to special remotes, but still do transfer
scans of them, after git pull from any other remotes, so we know about
any values that have been placed on them.
There are multiple reasons to do this:
* The local network may be up solid, but a route to a networked remote
is having trouble. Any transfers to it that fail should be retried.
* Someone might have wicd running, but like to bring up new networks
by hand too. This way, it'll eventually notice them.
This deals with interruptions in network connectevity, by listening
for a new network interface coming up (using dbus to see when
network-manager or wicd do it), and forcing a rescan of
