0ad436c337 AP_HAL_Linux: Scheduler: bring back scheduler table 
Use a scheduler table to list threads' properties in a single place.

a1b62b4984 AP_HAL_Linux: Scheduler: use PeriodicThread 
Some tasks were not accounting for the time to execute the tasks. Now
that we are using the infra from PeriodicThread all of them are.

48e81c8589 AP_HAL_Linux: Thread: add PeriodicThread helper 
This is a helper class to run a single periodic function like the ones
used in the scheduler.

to setup the thread.

9cf9fc152b AP_HAL_Linux: use pthread's barrier instead of polling 
Use pthread's barrier so we don't keep waking up threads with possibly
higher priority during initialization phase.

This also synchronizes all of them to a single point. With the previous
approach it was possible (but unlikely) that a thread hadn't reach the
synchronization point when main thread signalize "system initialized".

5bb2716081 AP_HAL_Linux: add name to SPI device table 
A string name allows to more easily expand the table: the board is
responsible for the name and doesn't have to declare it as a enum or
define. It's also easier to add 2 sensors of the same type.

2d3a62eae3 AP_HAL_Linux: RCInput_RPI: revert PWM support 
This reverts support for RCInput via PWM. This is causing trouble in
some RPI-based boards, receiving a SIGSEGV. Let's revert it for now and
retry this later.

This reverts commit 5629f38b2c.

of the main timer loop. This improves scheduling.

753f7d864a AP_HAL_Linux: add a shrink by software option in OpticalFlow 
This shrink must be used when the output camera sizes doesn't fit
the expected output.

We don't need to crop it even when the camera sizes aren't squared since
the shrink_8bpp() function shrinks a selected area.

553d36c860 AP_HAL_Linux: add shrink_8bpp() to VideoIn 
This function shrinks a selected area on a 8bpp image.

The focus in this function was the performance, so this may not be the
clearer or the most understandable way to write it. The performance
was measured using GoogleBenchmark[1].

a3cac102cd AP_HAL_Linux: AnalogIn_Raspilot: rename misleading variables 
We are not doing any dma here, it's just an SPI transaction. Name them
only rx/tx (although io_packet_tx/io_packet_rx could be another option).
This also zero-initialize the struct to keep valgrind happy about not
calling ioctl() with uninitialized variables.
