I made the MountWatcher only use dbus if it sees a client connected to dbus
that it knows will send mount events, or if it can start up such a client
via dbus. (Fancy!) Otherwise it falls back to polling. This should be enough
to support users who manually mount things -- if they have gvfs
installed, it'll be used to detect their manual mounts, even when a desktop
is not running, and if they don't have gvfs, they get polling.
Also, I got the MountWatcher to work with KDE. Found a dbus event that's
emitted when KDE mounts a drive, and this is also used. If anyone with
some other desktop environment wants me to add support for it, and it uses
dbus, it should be easy: Run `dbus-monitor`, plug in a drive, get
it mounted, and send me a transcript.
Of course, it'd also be nice to support anything similar on OSX that can
provide mount event notifications. Not a priority though, since the polling
code will work.

Some OS X fixes today..
* Jimmy pointed out that my `getmntent` code broke the build on OSX again.
Sorry about that.. I keep thinking Unix portability nightmares are a 80's
thing, not a 2010's thing. Anyway, adapted a lot of hackish C code
to emulate `getmntent` on BSD systems, and it seems to work. (I actually
think the BSD interface to this is saner than Linux's, but I'd rather have
either one than both, sigh..)
* Kqueue was blocking all the threads on OSX. This is fixed, and the
assistant seems to be working on OSX again.

I put together a preliminary page thanking everyone who contributed to the
git-annex Kickstarter. [[thanks]] The wall-o-names is scary crazy humbling.
----
Improved `--debug` mode for the assistant, now every thread says whenever
it's doing anything interesting, and also there are timestamps.
----
Had been meaning to get on with syncing to drives when they're mounted, but
got sidetracked with the above. Maybe tomorrow. I did think through it
in some detail as I was waking up this morning, and think I have a pretty
good handle on it.
