data: emit filename/lineno information for shell functions
Make it easier for users to debug shell task failure by including
some breadcrumbs in the emitted .run file that (hopefully) points
to the .bb/.bbclass file where the shell function was defined.
Unfortunately this won't work with functions with _append
or _prepends, since BitBake wipes the filename/lineno information.
This shouldn't be too hard to fix; for now, you'll just see
comments like this for such functions:
