Problem: If NVIM_LOG_FILE, or the default fallback, is inaccessible (e.g. directory is owned by root), users get confused. Solution: Show a warning when $NVIM_LOG_FILE or $XDG_STATE_HOME are inaccessible. Also fix a latent memory leak: `os_mkdir_recurse` returns a uv error code (int), but it was stored as `bool`, causing `os_strerror` to receive an invalid error code and leak memory.
