unicode-bidi: plaintext never worked properly when there is a line wrapping in a 
span with unicode-bidi: plaintext.
The problem happens because constructBidiRunsForSegment does not have
 enough logic to understand the difference between line wrapping vs line
 breaking, the current patch just adds the necessary logic(e.g when a text has a
 line wrapping it needs to determine the directionality of the paragraph from the beginning of the isolatedInline)

Move SharedBuffer into blink_platform.dll

This CL moves SharedBuffer and its dependencies into platform.dll. This CL is
interesting because it's the first time that blink_platform.dll will depend on
the Platform API and the first time that it will export symbols as part of the
API.

If a tree lays out in the forest and no one hears it, does it reach a milestone?

And what about it's relevant repaint rects?  Are they relevant?

It turns out, no.  At least not that Chromium cared.

Remove epic dead code.

This was added by Apple for WebKit2 but never used by Chromium:
http://trac.webkit.org/changeset/129545

I removed the didFirstLayout() callback from WebFrameClient, but could not remove didFirstVisuallyNonEmptyLayout as that's currently used by Android to set the background color.
