Integrate the gyro values pushed by the inertial sensor backend using
bias values sent by EKF.
Use the unblocking RingBuffer to avoid locking the callers.
- avoid trying to close fd when it's -1
- Keep includes sorted
- AP_HAL::panic() doesn't need \n terminator
- %u requires unsigned type
- #pragma once is the first thing on a header
when a library called read() it would clear the new input flag, which
would cause new_input() in the main loop to return false. This could
trigger a false RC failsafe.
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.
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.

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.

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.
Accidentally pushed in commit 298f7bffb9
The order of the motors shouldn't have been changed on version 5 because
it is specific to older versions of the ESC controller firmware
We currently check examples are buildable with waf which doesn't need
the libraries to be specified in a make.inc file. Having the makefiles
there is misleading since people try to build and realize the build is
broken.
this is a RCInput module for multiple R/C uart protocols running at
115200 baud 8-bit. We can decode multiple protocols in parallel with
this module, relying on frame timing and CRCs to get the right
protocol

25c7e8b changed the logic of transfer(). Align
I2CDevice::read_registers_multiple() in the same way.

If I2CDevice::transfer() has to do nothing it returns false. This can be
misleading, as this might feel contradictory.
Let's spend a comment on that.

According to man 3 ioctl, ioctl returns other values than -1 on success.
So loop while ioctl returns -1.
Furthermore, there is no necessity to initialise r with -EINVAL,

We aren't going to use all the poller infra for now and we need it's
behavior a little bit different for what we are going to use:
- Do not use any "fair" time for each ready fd since we don't want
to set a timeout
- Allow to set the fd on Pollable after constructing it since we are
likely to embed Pollable inside other structs and just later be
able to open an fd.
- Let caller use the epoll flags directly - this is not in AP_HAL,
so there's no need to abstract them
Add system's polling infrastructure to be notified whenever a
file descriptor is ready to be read from or written to.
Adds a few classes:
* Poller, as an interface to epoll()
* Pollable, as an interface to a file descriptor
