Close #4829

If the user has moved the extension dialog, we don't want to re-center it on every single update -- many extensions update their dialogs on every input change, and this behavior can cause the extension dialog to keep re-overlapping with the video, which is very frustrating.

This reverts commit cec6c32f.

Also remove the N*N controls config/var updates.

If regex was the first package installed it would create include
and lib files, instead of include/regex.h and lib/libregex.a

Choosing negative values for some of these settings is NOT a good idea if you
want to avoid damaging your ears ;-)

It is not available for a majority of VLC users so it should be off by default.

Thus we need to align the hardware width ourselves.

Note that this needs to be accounted for in the JNI support code.
