A new flash driver abstraction is also provided to allow
for future support of other types of flash device under
the filesystem.

When more than one task is concurrently trying to access
the same i2c bus and a timeout occurs on bus lock the
transfer would just continue and blow up the pios_i2c
driver. This has been fixed.
Actuator did not provide an option to completely shutdown selected channels
(set PWM pulse = 0). It is useful for camera stabilization boot delay (we
want few seconds of gimbal servo inactivity to calibrate gyros). It also
might be useful for failsafe on some channels. This option is now available.
It is used to disable camera outputs during fixed 7s delay after boot
instead of setting them to minimum position.
As a side effect, few bugs are fixed (ticks should be multiplied by
portTICK_RATE_MS, not divided, to get time in ms). And few floating point
operations were optimized out as well.
ActuatorCommand.UpdateTime was promoted to uint16 because it is not unusual
to have it 20000ms during flash updates (was seen on the CC after UAV
settings import). So it should be 16bit as well.
This is a partial rework of Cossacs' camera gimbal software.
This patch adds LPF to airframe attitude used for camera stabilisation
and feed forward for camera actuators. Either of options can be
disabled on the compilation level to save flash and RAM if not
required.
Original Cossacs' code was optimized and code flow shortcuts were
added where applicable.
This is a partial rework of Cossacs' camera gimbal software.
This patch adds LPF to some of manual control inputs. Mostly
useful are accessory channels (for camera gimbal control) and
yaw channel (for smooth filming). The code may be used for
stand-alone CC[3D]-based gimbal software, but also should work
for complete FC+camera system.
The uavo_handles section is not part of the .data segment so
it doesn't get automatically zeroed during the startup code.
This led to random data being stored in the table which resulted
in bus errors at runtime.
This change ensures that the table is zeroed before we start to
use it.
