Reviewed by Darin Adler.

Source/WebCore:

Giving line height to input elements increase the height
of the element. To make it work similiar as Mozilla and IE
line-height :normal should be applied for input elements.

Test: fast/dom/HTMLInputElement/input-line-height.html

* css/html.css:
(input):
Made the line-height: normal as !important so that it does not
consider any other line-height specified through internal or
external styles.

LayoutTests:

* fast/dom/HTMLInputElement/input-line-height-expected.txt: Added.
* fast/dom/HTMLInputElement/input-line-height.html: Added.

Added new test for verifying that giving line-height to input element
has no affect on its height.

* fast/forms/placeholder-position-expected.txt:
* platform/mac/fast/forms/placeholder-position-expected.png:

Rebaselining existing tests as per the new behavior. The position
of input elements have been modified since line-height is not being
considered.
