Instead of manually signalling the related events, use PurgeComm which
can then abort the operations itself. Also make sure all of the
relevant handles are set to INVALID before closing them to avoid race conditions.

The Windows modem driver is quite chatty at startup time, getting and
setting the comm parameters each time the device is opened. Sometimes,
when setting the parameters, the cc1111 would STALL EP0.
Most of the time, Windows would happily pass this as an error back to
AltosUI which would then re-try the open (and succeed, most of the
time).
Sometimes, Windows would stall for 30 seconds before passing the error
back. This made the whole UI freeze, and I suspect most people assumed
our app had died.
A bit of analysis with the beagle USB sniffer and I discovered the
STALL settings, but there wasn't any correlation between the data on
the wire and when the STALL would be generated.
So, I found a couple of other cc1111 USB stacks on the net and just
looked to see how our driver differed. There wasn't anything clearly
related, but there were a list of small differences:
1) Other drivers didn't bother waiting for the hardware to
ack the USBADDR setting; doing it this way means we can set
the address *before* acking the setup packet. It'll get
set eventually, at which point the device will start responding to
packets again.
Easy to fix, and saves a bit of code space too.
2) The other drivers set the STALL bit for setup packets which aren't
understood. This shouldn't have any effect on 'good' systems as
those shouldn't ever be generating bogus setup packets anyways.
The driver already handled the STALL state in the interrupt
handler, the only requirement was to figure out when to explicitly
set the STALL bit.
That required moving the state updating code from the start of the
ep0 setup handling to the end, after the setup packet had been
examined and data queued in or out as appropriate.
3) Our driver explicitly queued an IN packet for any setup request
that wasn't waiting for an OUT pack. This appears to tie in with
the USBADDR change above as before I made that change, this change
caused the driver to fail to respond to most setup packets.
This was simple once the above change was made, just move the
generation of the IN packet inside the code that switched to the
IN state.

GPS altitude is generally more absolutely correct than baro altitude,
so use that as the nominal pad altitude when generating a KML
file. This results in a KML file that has the flight trace start and
end closer to the ground, which is always nice.

State objects now record what GPS sequence ID they have to know when
the GPS data has been updated. Record objects bump the GPS sequence
each time new GPS data is recorded. This way, record objects aren't
modified as they're iterated over to generate the list of state
objects which makes it possible to iterate multiple times and get the
same resulting set of states.

Clearly the pin isn't quite ready just after it's been configured, so
hang around for a while (100 nops) to let things setting down before
testing the value of the pin. Makes booting a lot more reliable.
