Lucas De Marchi 7ba82ff23a AP_HAL_Linux: remove raspilot
It's not being sold, there are just a few (different) engineering
samples built and there are no plans for this to go forward for people
that were pushing it.

Lucas De Marchi 5ea1784838 global: remove AP_HAL::in_timerprocess()
This is not used and in the only places it would make sense would be
internally to the scheduler so remove it.

Lucas De Marchi 93a558ce5c AP_HAL_Linux: do not call delay callbacks on other threads
If a thread other than the main one calls Scheduler::delay() we could
end up triggering the call of delay callbacks. Those should only ever
happen on the main thread.

Lucas De Marchi e803045d1f AP_HAL_Linux: Scheduler: increase stack for scheduler threads
RPI-based boards that use RCInput_RPI need more stack space otherwise we
end up with stack corruption. This leads to crash particularly when also
using GPIO_RPI since it may change what that driver is poking on memory.

This increases stack size to 1M which is overkill for most of other
boards with a more controllable stack usage. However this exposes that
on multiple different HWs a single point for stack size decision may not
be the best.  This can be improved in future.

Ralf Ramsauer 530d3230df Linux: Scheduler: don't ignore return values
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.

Lucas De Marchi 37f6b51746 AP_HAL_Linux: Scheduler: set stack sizes to 256k
Running the vehicles we check the stack size doesn't grow too much by
enabling the DEBUG_STACK in the scheduler. Even on 64bit boards the
stack is consistent around 4k. Just to be a little conservative, let it
be a little bit more that that: 256kB.

Since we have RT prio and we call mlock(), the memory for the stack of
each thread is locked in memory. This means we are effectively taking
that much memory. The default stack size varies per distro, but it's
common to have 8MB for 64 bit boards and 4MB for 32 bit boards. Here is
the output of ps -L -o 'comm,rtprio,rss $(pidof arducopter-quad)', showing the
RSS of arducopter-quad before and after this change:

Before:
	COMMAND         RTPRIO   RSS
	arducopter-quad     12 46960

Lucas De Marchi 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".

Caio Marcelo de Oliveira Filho ff016c4b5a AP_HAL_Linux: implement new AP_HAL functions
Implement the new AP_HAL functions and use them in the Scheduler when
possible.

The '_sketch_start_time' was renamed and moved as a detail of
implementation of the functions code. It allows the code to return time
starting from zero.

The 'stopped_clock_usec' was renamed to follow convention in the file
and add a getter so that AP_HAL functions can reach it. It's not a
problem this getter is public because in practice, regular code
shouldn't even access the Linux::Scheduler directly -- only code that
should is from Linux implementation.

Lucas De Marchi 1b07dabeb7 Replace prog_char and prog_char_t with char
prog_char and prog_char_t are now the same as char on supported
platforms. So, just change all places that use them and prefer char
instead.

Lucas De Marchi 2c38e31c93 Remove use of PSTR
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.

This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.

AVR-specific places were not changed.
