Prepare to make WebUIMessageHandler conform to style guide.

WebUIMessageHandler had a protected data member WebUI* web_ui_.  In this CL,
there is now a protected accessor webui(), and the data member will be private,
as per the C++ style guide.

Unfortunately many files are affected by this change, but the correction just
involves changing:
  web_ui_->xxx;
to:
  web_ui()->xxx;

Fixing all the affected derived classes at once may be hard because there is
high traffic in WebUI development.  There are something like 86 files affected,
so I am only ADDING the protected accessor as a first pass, and then in a
subsequent CL I will fix affected handlers, and then finally there will be a CL
that makes the protected data member private.  This should reduce 
merge/build/review headaches.

BUG=None
TEST=None
