The current situation with SystemExit and soft reset is the following: - `sys.exit()` follows CPython and just raises `SystemExit`. - On the unix port, raising `SystemExit` quits the application/MicroPython, whether at the REPL or in code (this follows CPython behaviour). - On bare-metal ports, raising `SystemExit` at the REPL does nothing, raising it in code will stop the code and drop into the REPL. - `machine.soft_reset()` raises `SystemExit` but with a special flag set, and bare-metal targets check this flag when it propagates to the top-level and do a soft reset when they receive it. The original idea here was that a bare-metal target can't "quit" like the unix port can, and so dropping to the REPL was considered the same as "quit". But this bare-metal behaviour is arguably inconsistent with unix, and "quit" should mean terminate everything, including REPL access. This commit changes the behaviour to the following, which is more consistent: - Raising `SystemExit` on a bare-metal port will do a soft reset (unless the exception is caught by the application). - `machine.soft_reset()` is now equivalent to `sys.exit()`. - unix port behaviour remains unchanged. Tested running the test suite on an stm32 board and everything still passes, in particular tests that skip by raising `SystemExit` still correctly skip.
