Bug 31468 – Unify TextBoundaries implementations by only relying on WTF Unicode abstractions

• Status: RESOLVED
• Resolution: FIXED
• Component: Platform

[Dominik Röttsches (drott)]

Currently, there are multiple TextBoundaries implementations, one based on ICU (platform/text/TextBoundariesICU.cpp), one for QT (text/qt/TextBoundaries.cpp) - and for closing bug 15914, there would be another one needed for GTK/GLib. In order to reduce code duplication, I suggest to unify these into one, only using WTF abstractions.

Refactoring TextBoundariesICU.cpp into generic TextBoundaries.cpp

TextBoundaries.cpp intends to be equivalent to the TextBoundariesICU.cpp but is relying on internal abstractions. 
Removing unneeded ICU includes in SimpleFontDataGtk.cpp on the way.

I did not try to merge the Qt version of TextBoundaries.cpp - could someone from the Qt WebKit team look at whether that's desired? Who would be best CC'ed on this bug regarding this question?

Minor copyright fix.

We normally use "using namespace" to bring in the WTF Unicode functions. See this idiom in files such as Document.cpp, Font.cpp, and String.cpp.

This patch otherwise looks good to me.

Changed according to Darin's suggestion to use a "using namespace" declaration.

Changes to be committed also need an r+.   Looks sane to me too.

We have a bad JSC regression atm.  bug 31461.  Let's try again.

I'm in the process of moving the commit-queue to a new machine, and it's had hiccups.  Sorry.

My continued apologies.  I've reverted back to the old commit-queue machine
until I can figure out the build issue.  Hopefully the next run will not hit
the JSC crasher. :(

Windows and Chromium builds broke after the first commit.  The second commit was to fix them.

Thanks for additional review and build fixes, Eric!
