@JelleZijlstra Jelle, I've added tests and documentation)

In my personal view, according to the original issue, the intention behind adding the clear method is to allow array.array to implement collections.abc.MutableSequence, so we can add a test to test it and ensure we don't break it in the future.

@JelleZijlstra @aisk Guys, if I understand correctly, I made all the changes according to the reviews.
Please tell me what further steps are needed to merge the PR.

Thanks all for the efforts, sorry for tagging but gentle nudge to @vstinner who seems to have touched the relevant files recently (according to BLAME).

Thanks!
