Even if a text datablock was "used" by in the Text Editor, it would be
lost after save/reload if no fake user is set.
This is not in line with other datablocks if they are used by an editor
(e.g. images, clips, masks etc.).
Now handle this with `IDWALK_CB_USER_ONE` (instead of `IDWALK_CB_NOP`)
in `id_refcount_recompute_callback` >
`BKE_screen_foreach_id_screen_area` which re-ensures a user is set.
(Bit on shaky ground here, but this seems like this is how this is
handled for other editors "consuming" a datablock).

This change replaces a bare RenderEngine owned by a viewport
with a VeiwRender. This unlocks a possibility of accessing
RenderResult for viewport renders. Currently it is not done,
but it will be needed for an upcoming work towards unification
of the render passes handling.

Couldn't move two files yet:
* `softbody.c`: The corresponding regression test fails. It seems like the
conversion to C++ changes floating point accuracy, but it's not clear where that happens exactly.
* `writeffmpeg.c`: Is a bit more complex to convert because of the static array in `av_err2str`.
