uorb topics generator: add multi-topics to the list of all topics

topic names with '# TOPICS <name>' were previously not in orb_get_topics().
This means the logger could not find them.

Affects for example actuator_controls_0.

px_generate_uorb_topic_files.py: add multitopics to generate_topics_list_file_from_files method

switch simulated attitude to new topic: vehicle_attitude_groundtruth

logger: add input_rc topic. needed for web plotting

input_rc.msg: remove timestamp_publication, use timestamp instead

mixer.cpp: warnx -> PX4_ERR

logger: initialize timer_call to 0 (hrt_call_every reads some fields)

position_setpoint_triplet topic: set the timestamp when publishing

px_generate_uorb_topic_files.py: add multitopics to generate_topics_list_file_from_files method

add vehicle_attitude_groundtruth to default topics

change to hil_state_quaternion

topic names with '# TOPICS <name>' were previously not in orb_get_topics().
This means the logger could not find them.

Affects for example actuator_controls_0.

There are only two exposed serial connections, which are used as other things for the decks, so don't utilize any by default

nshterm should still work. Using low console instead which should just discard all characters for the plain system console

On second thought, using % just isn't correct. When a make
target looks like:

foo% bar%:
	...

Then that implies that it will build BOTH foo% and bar% whenever
that rule is triggered (by either) for any value of the pattern %.

Clearly that is not what we want / intend.

So, this commit goes back to using config targets without a % in it
by generating a full list of them.

It also turns sitl_deprecation into a Hidden Target.

Finally, now that we have those target lists anyway, I added
a 'help' and 'list_config_targets' targets that print the
available targets.

Note that the '%' catch-all target only works when all other targets
either have a recipe or are marked as .PHONY, otherwise such targets
are only interpretted as dependencies and still executre the '%'
target afterwards, which is not what we want.

* navigator/mavlink: always send last reached item

Since we can't rely on mavlink that every message arrives, it makes
sense to continuously send the last reached waypoint.

* navigator: don't report reached for takeoff

If a takeoff waypoint has been inserted, we should not report that we
reached a mavlink mission item because we actually have not.

* This allows one to run 'make posix list_vmd_make_targets' and get output like

>make posix list_vmd_make_targets

Or, run 'make list_vmd_make_targets' from the build_posix_* directory.

* This adds the list_cmake_targets make target to print all
cmake targets that one can match with PX4_NO_OPTIMIZATION.
PX4_NO_OPTIMIZATION is ignored (do optimization as normal)
when the CONFIG isn't posix_sitl_*.

* Add comment in Makefile on how/where to find all targets.

Use $(MAKE) -C build_dir ..., not (cd build_dir; make ...)
(ie, see https://blog.flameeyes.eu/2010/10/tell-tale-signs-that-your-makefile-is-broken)

Also talk about 'make targets' where appropriate, instead of 'cmake targets' %-).

This allows one to set a semi-colon separated list of regular
expressions in the environment variable PX4_NO_OPTIMIZATION
to control which (cmake generated) targets should be compiled
without optimization.

Suppressing optimization can be necessary for debugging in
a debugger, especially when trying to step through the code
or needing to print variables that otherwise are optimized out.

EXAMPLE

export PX4_NO_OPTIMIZATION="px4;^modules__uORB;^modules__systemlib$"

will result in the following messages during cmake configuration:

[...]
-- Disabling optimization for target 'platforms__posix__px4_layer'
because it matches the regexp 'px4' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__systemlib' because it
matches the regexp '^modules__systemlib$' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__uORB' because it matches
the regexp '^modules__uORB' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'examples__px4_simple_app' because
it matches the regexp 'px4' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'modules__uORB__uORB_tests' because
it matches the regexp '^modules__uORB' in env var PX4_NO_OPTIMIZATION
-- Disabling optimization for target 'px4' because it matches the regexp
'px4' in env var PX4_NO_OPTIMIZATION

Note that a list of all (currently used) target names can be printed
with the following command line from within the required build directory:

find . -wholename '*/CMakeFiles/*.dir/flags.make' | xargs dirname | xargs basename -a | sort -u | sed -e 's/.dir$//'

While the config_sitl_rcS_dir is used more extensively (and actually
only depending on the base cmake target), the variables
config_sitl_viewer and config_sitl_debugger are just used to be
passed on for the run_config target; config_sitl_debugger is even
*always* 'disable'. Hence, they don't really need to be cached
(INTERNAL or not). Before this patch FILEPATH was used instead
of INTERNAL, but I doubt very much that that was intended. That
only makes sense when cmake-gui would be used and then would pop-up
a file browser to let the user pick a file (while really they
need to pick a directory, so it's wrong either way).

The ONLY reason caching would be used is when a developer edits
the build_posix_sitl_*/CMakeCache.txt files, changes these values
and then runs cmake in the build directory again, now overriding
the values intended here. Nevertheless, I left in the caching.

The main change in this commit (that theoretically has no real effect)
is that I removed the duplicated maintenance of
posix_sitl_broadcast.cmake. When that file was added, it was an
exact copy of posix_sitl_default.cmake and is since not always
maintained to remain the same. I don't think that difference is
in anyway relevant for the broadcasting part though.

Note that I think that something like that also holds for the
posix_sitl_replay.cmake; it would be a lot better - maintenance-wise
- when it was just derived from (or the same as) posix_sitl_default,
I think.

Doesn't really do anything, but while working on understanding
things I did this cleanup, making the Makefile a lot shorter
and more flexible for future changes ;).

Over time I made a few changes unrelated to what I'm really working on.
These changes are hereby committed first. The bug fixes are related to
what I'm doing in that I need them to be fixed for future commits.

Tools/sitl_run.sh: rename label to rcS_dir and fix usage help.
cmake/common/px4_base.cmake: Remove the check on OUT_UNPARSED_ARGUMENTS,
  and a few typos and indentation issues.
cmake/configs/posix_sitl_replay.cmake: Set the correct variable
  (config_sitl_rcS_dir) to the correct directory.
cmake/nuttx/px4_impl_nuttx.cmake: typos and indentation issues,
  and removal of a redundant FORCE (INTERNAL implies FORCE).
cmake/posix/px4_impl_posix.cmake: typos and indentation issues.
cmake/qurt/px4_impl_qurt.cmake: typos and indentation issues.
src/modules/mavlink/mavlink_ftp.cpp : possible strict-aliasing breakage.

NOTES

The second argument passed to sitl_run.sh is the value of
config_sitl_rcS_dir. This fact is missing from the usage help.
I renamed 'label' to 'rcS_dir' to better reflect this.
Also, for the 'replay' config the wrong variable was set causing
the call to sitl_run.sh to skip an argument and fail (ie the
debugger was passed as rcS_dir and so on).

The check on OUT_UNPARSED_ARGUMENTS in px4_parse_function_args
basically causes every passed IN variable to be REQUIRED and is
therefore a bug. The test for the presence of the REQUIRED arguments
follows directly after and is sufficient for this job. This bug went
unnoticed because currently every argument to OPTIONS, ONE_VALUE,
and MULTI_VALUE is actually passed to the function(s) calling
px4_parse_function_args (them being REQUIRED or not).

The changes in mavlink_ftp.cpp are to avoid a possible aliasing bug
and (mostly) to avoid the compiler warning/error: dereferencing type-
punned pointer will break strict-aliasing rules [-Werror=strict-aliasing].
