AP_HAL_Linux: force Thread stack to have minimum size
Check that Thread stack size is the minimum allowed

Also add 256k to HAL-independent request stack size

Lucas De Marchi 3b2de6de46 AP_HAL_Linux: allow PeriodicThread to stop
This takes the simplest approach of just waiting for the next time we
will process events.

Lucas De Marchi da821e69eb AP_HAL_Linux: Thread: allow to use Thread from stack
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.

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.

Lucas De Marchi 359417d544 AP_HAL_Linux: Thread: make sure pointer is aligned
Implementation of alloca() is very much architecture and compiler
dependent. Avoid the case in which it could return a non-aligned
pointer, which would mean Thread::_poison_stack() would do the wrong
thing.
