scripts: runner: use arguments, not environment vars
The various runners (flash/debug scripts) use environment variables to
take arguments. This is legacy behavior which is not desirable.
Use command line arguments instead.
Note: this leaves more general environment variables with publicly
documented behavior in place for now, for compatibility, e.g.:
ZEPHYR_FLASH_OVER_DFU, OPENSDA_FW, ESP_IDF_PATH, PYOCD_DAPARG
For example, when using dfu-util to flash arduino_101, instead of
setting DFUUTIL_PID, DFUUTIL_ALT, and DFUUTIL_IMG environment
variables, have the script invocation look like this:
python3 .../zephyr_flash_debug.py dfu-util flash \
[common arguments omitted] \
--pid=8087:0aba --alt=x86_app \
--img=.../build/zephyr/zephyr.bin
Make similar changes for other runners (openocd, etc.) and
targets (debug, debugserver).
To implement this in the scripts:
- have the individual scripts/support/runner/some-runner.py files
register their own command line arguments
- teach them to construct instances from arguments, not the
environment
- have zephyr_flash_debug.py request runners to register command
line argument parsers, and handle arguments
In the build system:
- add a new board_runner_args() extension function that board.cmake
files can use to add to the zephyr_flash_debug.py command line
- adjust cmake/flash/CMakeLists.txt to invoke with arguments
- add new helper include files for each runner (like
boards/common/dfu-util.board.cmake, etc.), which add default
options as needed and then add on overrides from
board_runner_args() calls
- update board.cmake files to use the new includes and extension
This implied some tweaking when using openocd to make the CMake string
escaping and unescaping work properly.
