Peter Barker fa7ba7ddbc DataFlash: force messagewriters to completion 
Setting a dataflash-file buffer size of less than or equal to 2kiB would
cause the startup-messagewriter to never push any messages other than
FMT out to the logs.

This is a combination of the return values of
critical_message_reserved_space and
non_messagewriter_message_reserved_space

This patch forces the startup messages out to the logs by ignoring the
space constraints every 100ms

Andrew Tridgell 777b4c8cfe DataFlash: avoid stat of current log file 
this avoids getting invalid data base for stat() for the current log
file.

It also only gives up writing to a log file if writes fail for 2
seconds. This avoids a temporary write failure causing the log to be
closed (that can happen on ChibiOS with directory listing while writing)

If the sensor threads are using WriteBlock they may pass the _write_fd

Murilo Belluzzo c112e1c889 DataFlash: Make use of ByteBuffer class 
This patch replaces the 'old style' ringbuffer by the ByteBuffer class.
An effort was made to keep the exchange as close as possible from a
drop-in replacement to minimize the risk of introducing bugs.

Although the exchange opens opportunities for improvement and
simplification of this class.

Mathieu OTHACEHE 152edf7189 Global: remove mode line from headers 
Using a global .dir-locals.el file is a better alternative than
reincluding the same emacs header in every file of the project.

Andrew Tridgell b967140572 DataFlash: enable minimal file mode 
This adds a "minimal" dataflash mode with a board specific macro. The
QURT port uses this to avoid problematic system calls that are buggy
in the QURT RTOS

With some pending updates to QURT we may be able to remove some (or
all) of this

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
