This reverts commit def8c946.

After the major bump this is no longer necessary.

In addition to the recent tables mess, the AVOption defaults behavior

up defaults.

This reverts commit d15c21e5.

After the major bump this is no longer necessary.

Fixes a crash when using a preset with stream copy.
