3c2dffa601 scripts: trace_capture_usb: disable tracing on exit
Disable tracing on exit and do not discard data immediately after
enabling tracing. The length of the data depends on the timings of the
host and targets and may simply be an arbitrary length that does not fit
any trace format or frame.

66577a9d23 tracing: add named event trace
Add support for a "named event" trace. This trace is intentionally not
used by the system. The purpose of this trace is to allow driver or
application developers to quickly add tracing for events for debug
purposes, and to provide an example of how tracing subsystems can be
extended with additional trace identifiers.

ec7044437e treewide: Disable automatic argparse argument shortening
Disables allowing the python argparse library from automatically
shortening command line arguments, this prevents issues whereby
a new command is added and code that wrongly uses the shortened
command of an existing argument which is the same as the new
command being added will silently change script behaviour.

Generate trace using samples/subsys/tracing for example:

    west build -b qemu_x86 samples/subsys/tracing  -t run \
      -- -DCONF_FILE=prj_uart_ctf.conf

    mkdir ctf
    cp build/channel0_0 ctf/
    cp subsys/tracing/ctf/tsdl/metadata ctf/
    ./scripts/tracing/parse_ctf.py -t ctf
