Bug 989130 - Back out changeset fe119a83b1f2 (bug 942017) while leaving the corresponding test from changeset 3c63decb4e7e.  r=jfkthame  approval-mozilla-beta=sylvestre

This should be backed out for two reasons:

 (1) It caused a serious regression with bullets from list-style-image,
     which no longer affect the line box height and thus overlap.

 (2) The dependency on 'line-height: normal' doesn't make sense; there's
     no reason for whether line-height is 'normal' or not to affect the
     behavior of bullets.

I don't currently have time to figure out why Gecko behavior differs
from other browsers on bug 942017, but that should be re-analyzed and
the bug fixed in a different way.  At first glance, the code should
already be leading to the expected behavior, since the bullet ought to
have the same metrics and alignment as the block's influence on the line
box's height.  Why this isn't the case should be investigated.
