Move chrome/browser/gtk/ to chrome/browser/ui/gtk/
(moved *.cc using 'svn mv' to preserve history)
(copied *.h using 'svn cp' to preserve history and stub out originals)
Stubbed out original headers in chrome/browser/gtk/
Update header guards & copyright dates in chrome/browser/ui/gtk/
Update .gypi files
Remove chrome/chrome_browser.gypi:4228 reference to nonexistant:
['include', '^browser/gtk/pk11_password_dialog.h'],
Remove stray header guard in:
chrome/browser/ui/gtk/bookmark_bar_instructions_gtk.cc
Add #pragma once to the following files:
chrome/browser/ui/gtk/instant_confirm_dialog_gtk.h
chrome/browser/ui/gtk/infobar_arrow_model.h
Ran the following to appease presubmit: 'svn pset svn:eol-style LF \
