Remove remaining APPLE_CHANGES and KHTML_NO_CPP_DOM blocks from WebCore

The previous bug:
http://bugzilla.opendarwin.org/show_bug.cgi?id=5711
only removed APPLE_CHANGES from WebCore/khtml

This removes all the rest from WebCore (kwq mostly), with the exception of SVG, and additionally removes 
all KHTML_NO_CPP_DOM blocks.

The patch

This also removes all #if 0 blocks (which may or may not be a good thing).

The patch

This patch shows lots of cases where it leaves stray multiple blank lines. So
it's going to leave formatting a little messy. I'd like to see a version that
has a heuristic for nicely eating the excess blank lines.

I also see cases where there's a comment just before an #if 0 section. This
patch is going to lave those comments stranded. An example is in DOMHTML.mm.

Some of this already probably took place with the last "remove ifdefs" patch,
which I did not review in detail.

Responding to Darin's comments.

To address Darin's concerns, I did a couple things:

1.  I did a search throughout the entire project looking for "excessive"
newlines and removed them.
2.  I did a manual review of each of the previously changed files and removed
any extra comments, newlines.
3.  I removed dom_misc.* entirely, and moved the remaining DOM::EventListener
and DOM::NodeFilterCondition onto khtml::Shared<T>
4.  As part of my manual walk through khtml_part.cpp I removed
DIRECT_LINKAGE_TO_ECMA as well.

The patch

Retracting review on this one for now.	See the new larger patch instead.

Responding to Darin's comments.

Here's an example of the kind of blank line thing I'm not so happy about:

---------

 #include "khtmlpart_p.h"

-#if !KHTML_NO_CPLUSPLUS_DOM
-#include "dom/html_document.h"
-#endif

 #include <CoreServices/CoreServices.h>

---------

and here's another:

---------

   cancelRedirection();

-#if !KHTML_NO_CPLUSPLUS_DOM
-  // null node activated.
-  emit nodeActivated(Node());
-#endif
 }

---------

Otherwise, this patch looks fine.

This is a simpler patch which is entirely script generated and addresses
darin's whitespace concerns.  Script is also attached to the bug.  This should
be a trivial review which any reviewer should feel comfortable with.
