Separating out the close and free actions ensures that the reader thread will not
access freed memory or dereference a null pointer while shutting down the
connection to the serial device. Otherwise, a race condition exists between the
serial close and the thread join.

This adds a custom dialog for selecting device, which makes it look
much nicer on the screen and allows the user to double-click on an
entry to select it.

Use GridBagLayout to improve the appearance of the flight data monitor
widget, add a cancel button to stop loading data (useful if the
connection is wedged).

downloading stuff from telemetrum.

Make sure it says something at the end of a log file replay.
Make sure it reports max speed after motor burn out, and max height
after apogee.

Add methods that format stuff using String.format for voice and serial
link, remove AltosSerialReader class and just embed that in the
AltosSerial class directly.

Because ao_log_data is called from two different threads, failing to
make it re-entrant would cause the 'log' pointer parameter to get
overwritten if another thread asked to log data while the eeprom was
busy writing out a block.
This would cause the second thread to re-writing data from the first
thread's address, but without re-checksumming the data as the checksum
is computed before the log mutex is taken.
The bug can be seen by log blocks with invalid checksums.
Here's what happens with the ao_gps_tracking_report and ao_log threads:
ao_gps_tracking_report ao_log
Writes a bunch of records
*blocks* in the eeprom flush
sets ao_log_data 'log' to global 'log'
computes checksum for 'log' block
*blocks* on ao_log_mutex
Wakes up
sets ao_log_data 'log' to 'gps_log'
writes remaining records
'gps_log' is left with svid = 0
*blocks* on ao_gps_tracking_data
writes data, reading from
the current ao_log_data 'log'
pointer which points at 'gps_log'
Making ao_log_data re-entrant fixes this by ensuring that the 'ao_log'
thread has its own copy of the ao_log_data 'log' parameter.
I made this function take an __xdata restricted pointer so that it
could be passed in the dptr register instead of needing to go on the stack.

If the host doesn't pull the IN packet out of EP0 before sending
another SETUP command along, the IN buffer will still be busy when we
try to reply to the SETUP command. While I don't quite understand why
this would ever happen, there's no need to panic about it, just drop
the reply packet on the floor.

If you want to use TeleMetrum as a debug dongle, you need to flip the
three pins used to talk to the remote debug port from SPI mode to GPIO
mode.
This patch doesn't provide any way to get back to SPI mode, so you'll
have to reboot the TeleMetrum to write out config parameters or log
flight data after using any debug commands.
