Anas Nashif 270be80caa tracing: add empty test macros
Add support for new tracing macros in test backend. Move header from
sample into the subsystem and make it available for general testing with
any application.

Title: Send Tracing Formated Packet To The Host With Supported Backends

Description:

This application can be used to demonstrate the tracing feature. The tracing
formated packet will be sent to the host with the currently supported tracing
backend under tracing generic infrastructure.

--------------------------------------------------------------------------------

Usage for UART Tracing Backend:

Build a UART-tracing image with:

    cmake -DBOARD=mps2_an521 -DCONF_FILE=prj_uart.conf ..

or:

    cmake -DBOARD=mps2_an521 -DCONF_FILE=prj_uart_ctf.conf ..

After the application has run for a while, check the trace output file.

--------------------------------------------------------------------------------

Usage for USB Tracing Backend

Build a USB-tracing image with:

    cmake -DBOARD=sam_e70_xplained -DCONF_FILE=prj_usb.conf ..

or:

    cmake -DBOARD=sam_e70_xplained -DCONF_FILE=prj_usb_ctf.conf ..

After the serial console has stable output like this:

    threadA: Hello World!
    threadB: Hello World!
    threadA: Hello World!
    threadB: Hello World!

connect the board's USB port to the host device and
run the trace_capture_usb.py script on the host:

    sudo python3 trace_capture_usb.py -v 0x2FE9 -p 0x100 -o channel0_0

The VID and PID of USB device can be configured, just adjusting it accordingly.

--------------------------------------------------------------------------------

Usage for POSIX Tracing Backend

Build a POSIX-tracing image with:

    cmake -DBOARD=native_posix -DCONF_FILE=prj_native_posix.conf ..

or:

    cmake -DBOARD=native_posix -DCONF_FILE=prj_native_posix_ctf.conf ..

After the application has run for a while, check the trace output file.
