Description changed by jdemeyer:
Old description:
> 1. Get rid of `coerce.pxi` and move the functions from there to more
> appropriate places.
> 2. Define the global `parent()` function in `structure/element.pyx` and
> document it.
> 3. Move `have_same_parent()` to `structure/element.pyx`.
> 4. Remove superfluous `parent()` methods (where `parent()` is defined
> exactly as in the base `Element` class, so by inheritance it's not
> needed).
New description:
1. Keep only `inplace_threshold` in `coerce.pxi` (that can be dealt with
in another ticket) and move everything else to more appropriate places.
2. Define the global `parent()` function in `structure/element.pyx` and
document it.
3. Move `have_same_parent()` to `structure/element.pyx`.
4. Remove superfluous `parent()` methods (where `parent()` is defined
exactly as in the base `Element` class, so by inheritance it's not
needed).
