* chore(organization): allow nested header and c files * feat: add shell login "middleware" & etc: * lidm now calls `bash` (or other shells, depends on PACKAGE cfg) in login mode as a session wrapper to source most env (can be disabled) * this fixes a lot of env problems with all `/etc/profile` and more Extra: * implemented a musl compatible version of `execvpe` and now lidm should search for PATH everywhere it needs to * `search_path` now also checks if the found binary is properly executable * lidm now uses `confstr` for a decent PATH default if none is found * logs are unbuffered for cases where debug logs appear empty (exit without handlers moment) * chore: one-time evaluate certain makefile vars --------- Co-authored-by: grialion <48643945+grialion@users.noreply.github.com>
