Make code compile with clang_use_chrome_plugin (part IV)

This change mainly contains files in fpdfsdk/ directory.
This is part of the efforts to make PDFium code compilable
by Clang chromium style plugins.

The changes are mainly the following:
-- move inline constructor/destructor of complex class/struct out-of-line;
-- add constructor/destructor of complex class/struct if not
 explicitly defined;
-- add explicit out-of-line copy constructor when needed;
-- move inline virtual functions out-of-line;
-- Properly mark virtual functions with 'override';
-- some minor cleanups plus removing an unused file and splitting
cxfa_eventparam out from fxfa.h
