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:

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.

AVR-specific places were not changed.

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.

Lucas De Marchi 54c2c5f682 AP_HAL_Linux: use method for downcast
Instead of just doing a static cast to the desired class, use a method
named "from". Pros:

  - When we have data shared on the parent class, the code is cleaner in
    child class when it needs to access this data. Almost all the data
    we use in AP_HAL benefits from this

  - There's a minimal type checking because now we are using a method
    that can only receive the type of the parent class

Gustavo Jose de Sousa 124b750c10 AP_HAL_Linux: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Staroselskii Georgii f4d14f73ba AP_HAL_Linux: extended panic handling with RCInput deinitialization
The issue has already come up. There's no deinitialization mechanisms at the moment. As APM is rather software than firmware on Linux, there're some clean-up work that needs to be done. This commit triggers deinitialization of RCInput on a panic.

Lucas De Marchi f049c8e4c5 AP_HAL_Linux: remove needless call to mlockall()
All threads share the same address space and have the same pages locked
into memory so it's not necessary to call mlockall() for each of them.

Grepping /proc/<tid>/status gives the same VmLck for all of them, even
when only the main thread locks the memory:

    # for i in `seq 477 482`; do \
	name=$(cat /proc/$i/comm); \
	vm=$(cat /proc/$i/status |grep VmLck); \
        echo -e "$name\t$vm"; \
    done

Lucas De Marchi e3d78b8960 AP_HAL_Linux: fix passing callback to member function
It's undefined behavior to pass the callback to pthread to a class
member like we were doing. Refactor the code so the callbacks are static
members.
