-rw-rw-r-- 1 pbarker pbarker         3 Jul  1 19:46 LASTLOG.TXT

Before fix:

2 logs
Log 3 in logs/3.BIN of size 2494464 2015/7/1 6:58
Log 4 in logs/4.BIN of size 128503808 2015/7/1 10:22

After Fix:

4 logs
Log 1 in logs/1.BIN of size 2105344 2015/7/1 6:10
Log 2 in logs/2.BIN of size 0 2015/7/1 9:35
Log 3 in logs/3.BIN of size 2494464 2015/7/1 6:58
Log 4 in logs/4.BIN of size 128503808 2015/7/1 10:22

If the last file was zero bytes, no files would be shown.

Andrew Tridgell c93ae67541 DataFlash: don't try and open logfile on failure more than once 
this prevents a corrupted microSD card from causing a continuous
attempt to open a log file while in flight, which can cause large
scheduler delays

Andrew Tridgell 916e8d0992 DataFlash: new dataflash logging system 
this allows us to remove the display functions in the vehicle code,
and also allows us to store the format of a log file in the log. It
also stores the parameters used in a flight, rather than the
parameters set at the time the log is dumped
