Flip the win-xp port to use apache by default for webkit_tests

Previously it was using lighttpd; flipping the default means that
we will be using apache everywhere, and we can proceed to
deleting all of the lighttpd code.

For font weights >= 600, create bold system fonts.

Adjust the weight threshold used for creating bold system fonts down
to 600, so as align with the weight matching specified by

  http://www.w3.org/TR/CSS21/fonts.html#propdef-font-weight

It also aligns better with others.

Node.replaceChild and Node.removeChild do not use custom binding anymore

This CL made those two methods use code generation
by removing Custom keyword from Node.idl
Then enabled interface type checking so appropriate TypeError
will be thrown as per sepc.

DevTools: ViewportControl.scrollIntoView synchronously updates viewport

This patch makes ViewportControl.scrollIntoView to synchronously update
its viewport.

As a result, it becomes legit to fetch rendered element
via ViewportControl.renderedElementAt after bringing it into viewport.
(that's what FilteredItemSelectionDialog does in its _updateSelection
method)
