The -b (build database) and -s (sync defconfigs) options currently spawn make subprocesses for every board, requiring cross-compiler toolchains. It is dog slow, taking several minutes.
This series replaces both paths with direct kconfiglib evaluation, reducing the time to under two seconds for ~1500 boards with no toolchain requirement. The series starts by fixing a long-standing kconfiglib bug where backslash sequences in string values (like \n in CONFIG_AUTOBOOT_PROMPT) were silently corrupted during round-trips. To prepare for the conversion, the database code is refactored so that buildman can read and build the CONFIG database directly, and defconfigs can be selected on the command line without using stdin. A resync is neutral: the effective config is unchanged and only the defconfig text is brought to canonical minimal form. Defconfigs which use #include directives are handled too, updating the overlay entries while preserving the include structure; entries which merely restate the include files are left alone, to avoid churn. Every updated defconfig produces a byte-identical .config when processed by the C Kconfig implementation. The -r (git-ref) option is converted as well. With all operations now using kconfiglib, the old make-based infrastructure (move_config(), Slot, Slots, KconfigParser and related helpers) is removed, dropping ~500 lines. The tool still grows overall, mostly due to the #include-defconfig handling and its unit tests. Finally, qconfig's tests are added to the test runner. The first two qconfig patches were sent in October 2024 (the -D patch with a Reviewed-by from Tom) but were never applied; they are included here with only minor commit-message and docstring tweaks.
