This adds the env option PX4_FUZZ which runs the LLVM libFuzzer which
throws random bytes at mavlink_receiver using MAVLink messages over UDP.
The MAVLink messages that are being sent are valid, so the CRC is
calculated but the payload and msgid, etc. are generally garbage, unless
the fuzzing gets a msgid right by chance.
As I understand it, libFuzzer watches the test coverage and will try to
execute as much of the code as possible.
This is already removed from nuttx, and in posix the size of s->last_times
can be just checked with sizeof()

Using cmake_host_system_information, grabs AVAILABLE_PHYSICAL_MEMORY and adds another job for every 1.5GB of available memory.
This is tested on a single system with 16 logical cores and 16GB RAM (~11.5GB available, reported correctly by cmake).
Using mixers on the IO side had a remote benefit of being able to
override all control surfaces with a radio remote on a fixed wing.
This ended up not being used that much and since the original design
10 years ago (2011) we have been able to convince ourselves that the
overall system stability is at a level where this marginal benefit,
which is not present on multicopters, is not worth the hazzle.

This commit adds SITL support for ignition gazebo. Ignition gazebo is a replacement for the "classic" gazebo for future applications.
The simulation can be run as the following
```
make px4_sitl ignition
```
- control allocation module with multirotor, VTOL standard, and tiltrotor support
- angular_velocity_controller
- See https://github.com/PX4/PX4-Autopilot/pull/13351 for details

Set CMAKE_RUNTIME_OUTPUT_DIR_DEBUG & _RELEASE to match
CMAKE_RUNTIME_OUTPUT_DIR as is already done in top level CMakeLists.txt.
Fixes Issue 16445 - px4-alias.sh: not found

This changes px4_task_spawn_cmd to match the NuttX task_spawn. It adds
the task name as argv[0]. See example below:
px4_task_spawn_cmd("task_name",
SCHED_DEFAULT,
SCHED_PRIORITY_DEFAULT,
1024,
(px4_main_t)&Something::start_helper,
(char *const *)argv);
with:
argv[0]: "something"
argv[1]: "start"
argv[2]: nullptr
becomes in Something::start_helper:
argv[0]: "task_name"
argv[1]: "something"
argv[2]: "start"
argv[3]: nullptr
* add basic mlock support to increase stability when system is under high load and RAM is almost full
* mainly about minimizing or completely eliminating RAM page swap time
* Add techpod SITL target
This adds a SITL target forthe techpod fixedwing model
* Update sitl_gazebo submoudle
This submodule update includes the techpod UAV model
- drivers/tone_alarm: move to ModuleBase and purge CDev (/dev/tone_alarm0)
- drivers/tone_alarm: only run on tune_control publication (or scheduled note) rather than continuously
- drivers/tone_alarm: use HRT to schedule tone stop (prevents potential disruption)
- msg/tune_control: add tune_id numbering
- systemcmds/tune_control: add "error" special case tune_id
- move all tune_control publication to new uORB::PublicationQueued<>
- start tone_alarm immediately after board defaults are loaded to fix potential startup issues
- for SITL (or other boards with no TONE output) print common messages (startup, error, etc)
