When PWM_Sysfs_Base constructor is called, global variable hal may not
have been initialized resulting in NULL dereferencing error.
Move hal dependent stuff from contructor to init method.
By opening with O_CLOEXEC we make sure we don't leak the file descriptor
when we are exec'ing or calling out subprograms. Right now we currently
don't do it so there's no harm, but it's good practice in Linux to have
it.

If there's a lot of messages in the queue, params would not be
transmitted for a while, until the queue is empty, which can take a bit
of time during init.
Several return values in the constructor of the scheduler were ignored
before, while they should be respected.
I found that bug while strac'ing ardupilot as it failed at some later
point.

This allows to terminate the flight stack nicely, ensuring it returns 0
so init system can check by return code if it terminated nicely or if it
was due to a crash.
This allows to wakeup the thread that is sleeping on Poller::poll()
[ which in our case is an epoll_wait() call ]. This is usually achieved
by using a special signal and using the pwait() variant of the sleeping
function (or using signalfd). However integrating the signal in the
Thread class is more complex than simply use the eventfd syscall which
can serve our needs.
Up until now we rely on Thread objects and variants thereof to be allocated
on heap or embedded in another object that's zero'ed on initialization.
However sometimes it's convenient to be able to use them on stack as
will be the case when writting unit tests.
Initialize all relevant fields to allow them to be used on stack. While
at it, prefer C++11 initialization on Poller since it's only setting the
default (invalid) value.

Notify users of the potential for velocity noise when using larger offset values..
Specific advice in terms of values has not been provided because it is highly dependent on Gyro noise levels.
This can improve position hold performance where it is not practical to have the IMU located at the centroid.
Although this enables the effect of IMU position offsets to be corrected, users will still need to be instructed to place the IMU as close to the vehicle c.g. as practical as correcting for large offsets makes the velocity estimates noisy.
Correction requires the body rates averaged across the flow sensor sampling interval. This data has been added to the sensor buffer.
The body rate data from the flow sensor driver does not contain the Z component, so an equivalent value sampled from the navigation IMU has been used instead.
The variable omegaAcrossFlowTime has been moved out of the class and into the only function that uses it.
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.
When the buffer wraps and we do it in 2 steps, we can't actually do the
second part if it fails or if we wrote less bytes than we intended,
otherwise we will corrupt the data being sent.
We can't give the TX buffer 16 bytes more since next time begin() is
called it will compare the buffer size to the value the caller is trying
to set. In this case we would free and alloc the buffer again each time
begin was called.

Summary of significant changes:
-Autsave doesn't depend on STREAM_EXTRA3
-Don't risk only saving one compass on copter if CAL_ALWAYS_REBOOT is set
-Only calibrate compasses that are both health and marked for use (there was a inconsistency in handling the mask)
-Fix incorrect failure reporting on DO_ACCEPT_MAG_CAL with a mask of 0 if a channel was specifically not started
-Fix not starting the buzzer if the delay is set to 0 seconds
-Always send MAG_CAL_REPORT until its acknowledged
-Correct the field in MAG_CAL_REPORT for autosave to indicate if the compass had actually been saved, rather then being scheduled to be saved
-Remmove unused public interfaces
The constant passed to cflag is BOTHER, meaning the actual baud is set
in the other specific members. Don't define B* constants as they are
misleading here and this is why it doesn't work with e.g.
cfset[io]speed()... that function expect a B* constant which in Linux
is not the speed, but an index to an array with speeds.
