This series adds infrastructure for passing runtime arguments from Python tests to C unit tests. This makes it easier to support a hybrid testing approach where Python handles complex setup (filesystem images, environment configuration) while C handles the actual test logic with better debuggability. A few other things are included to make this work: - A fix for linker list alignment that was causing garbage values like "Running -858993444 bloblist tests" due to GCC's magic-number division optimization failing when padding breaks exact multiples - A fix fix for serial output with sandbox, since it sometimes misses output at the end when running tests with gnome terminal - Improvements to the linker-list script to detect padding and pointer-arithmetic bugs - A new UNIT_TEST_ARGS() macro for declaring tests with typed arguments, along with argument parsing in the ut command (name=value format) - Argument-accessor macros ut_str(), ut_int(), and ut_bool() with type-checking and bounds validation - A private buffer (uts->priv) for test-local temporary data, which makes it a little easier to write shorter tests - Tests for the argument feature (test_args) covering type checking, bounds checking, and argument-parsing failures As an example, the basic filesystem tests are converted from pure Python to C with Python wrappers. Some improved printf documentation and support for Linux's %pV format are provided. The slight increase in size causes qemu-riscv64_spl to fail, so this series also includes a patch to increase the SPL-malloc() space.
