Fixes these invalid format strings:
- A `%d` for a pointer (replaced it by `%p`)
- A 0x%08x (and a 0x%0x8!) for a pointer (replaced by %p)
- 2 cases of `%d` for a `ssize_t` (replaced it by `%zi`)
- 1 case of a %u for an `int` (replaced by %i)
- 3 cases of %d for a `long` (replaced by %ld)
- 19 cases of `%d`, `%i`, `%u` or `%lu` for a `size_t` (replaced it by `%zu`)
- An unused formatting argument (removed it)
- A missing `%d` (added it)
- A missing `%s` (added it)
- 2 cases of `%llu` for a `uint64_t` (replaced it by `"%" PRIu64`)
- 6 cases of giving a string directly as format string (replaced it by `("%s", string)`)
- 2 cases of %*-s, which should probably have been %-*s.
  (Looks like NuttX accepts (the invalid) %*-s, but other platforms don't.)
- A %04x for a `uint32_t` (replaced by "%04" PRIx32)

   This common code can be used byt posix based boars to provide
   the board_identity API.

This uses the systems default shell:
- Ubuntu: dash
- Fedora: bash

Since bash is invoked via /bin/sh, it operates in POSIX mode:
  https://tiswww.case.edu/php/chet/bash/POSIX

- remove '# Ignore the expand_aliases command in zshell.'
  Not needed because the shell operates in POSIX mode
- [[ is bashism -> use [
- autostart_files=( $autostart_file_match )
  is not supported in dash, so use 'ls'
- shellcheck runs the dash flavor, since dash is a minimalistic shell.

Tested on dash & bash.

to make it non-blocking and ommit opening the same
named pipe multiple times inside the same process
which seems to be not supported in cygwin.

- Environment variables for building with asan
- Docker argument for leak sanitizer
- Regex for tests to fail on sanitizer error

- if somebody tries to use the shell with insufficient permissions he will be told so

Not needed anymore

Generally exit() should not be used on Posix, because it exits the whole
program instead of only the task.

 - fix ocpoc line endings

The command is now: 'make posix none_shell'
which means: don't start a simulator and run a minimal shell only.

The FIFO was created in the server thread, and the PX4 main thread could
already have continued and started to execute the bash script.
In that case the client tried to open the FIFO but it did not exist yet.

Client error:
ERROR [px4_daemon] pipe open fail
ERROR [px4_daemon] Could not send commands

Move ros logs dir so that .ulg files are not in the same directory
(mission_test.py:: get_last_log() fails otherwise)

Also ignore the warning:
error: calling 'system' uses a command processor [cert-env33-c,-warnings-as-errors]

By reading sizeof(packet), it could have happened that 2 packets at once
were read, and the second one was then ignored.
This makes sure that only one packet at a time is read.

The other 2 changes are for efficiency.

It was not enough to lock individual accesses to the maps.
For example it could happen that a thread was started and exited very
quickly, before the pthread_t item was inserted into the map, such
that when the cleanup method was called, the thread and pipe fd were not
found (and fd=0=stdin was closed).

The enum change from uint8_t to an int avoids uninitialized bytes,
which led to valgrind warnings (no error though).

- RPi works
- the rest is not tested, and requires a bit more
  (such as uploading the bin/ directory)

- move posix-configs/SITL/init/{rcS,10016_iris,6011_typhoon_h480} to ROMFS/px4fmu_common/init.d-posix
  allows for easier unification, only one symlink is required.
  - rcS: add AUTOCNF support. Update scripts to match with behavior of PX4
    master (parameter values, some sitl driver got removed)
- add alias to allow 'set variable value' syntax in scripts to px4-alias.sh
- use px4_getopt
- use separate argument for the test_data directory
- append PATH from within the px4 binary: this simplifies the usage
  w/o the sitl_run.sh script.
- add 'source px4-alias.sh' to all existing sitl startup scripts
- move sitl mixers to ROMFS/px4fmu_common/mixers-sitl
  makes it easier to use existing mixers and sitl-specific ones.
- remove unused rcS_gazebo_delta_wing

- argv[0] can have the form ./px4-commander
- create eeprom directory
- fix fpe signal handler
