This is the very preliminary implementation to support printing on Linux and it
has not been finished yet. For each page to be printed, we convert rendering
actions on canvas into cairo APIs and generate a PS/PDF file.

chrome/chrome.gyp:
  Include our newly added and renamed files.

chrome/browser/browser.h:
chrome/browser/browser.cc:
  Allow the user print the web page by hitting ctrl-p.

chrome/browser/gtk/standard_menus.cc:
  Show "Print" in the menu.

chrome/renderer/print_web_view_helper.cc:
chrome/renderer/print_web_view_helper.h:
chrome/renderer/print_web_view_helper_mac.cc
chrome/renderer/print_web_view_helper_win.cc
  Move the class PrepareFrameAndViewForPrint to the header file and move
platform dependent parts to their corresponding files.

chrome/renderer/print_web_view_helper_linux.cc:
  Hard-coded parameters for printing. Only print the first page now.

skia/ext/vector_canvas.cc:
skia/ext/vector_canvas.h:
skia/ext/vector_canvas_linux.cc:
skia/ext/vector_canvas_win.cc:
  Move platform dependent parts to their corresponding files.

skia/ext/vector_platform_device.h:
skia/ext/vector_platform_device_linux.cc:
skia/ext/vector_platform_device_linux.h
  We translate skia APIs into Cairo APIs here. A PDF file is also created and
saved to the disk at this moment for testing purpose (you have to run chrome
without the sandbox to save the file). There are still lots of bugs.

skia/skia.gyp:
  Include our newly added files when compiling skia package on Linux.

BUG=9847
