Fix problems with odocstream on "exotic" systems caused by the strfwd gimmick.

Browse Source 
* src/support/docstream.{cpp,h}:
	Move insertion operator for char types from docstream.h to
	docstream.cpp and compile it only when USE_WCHAR_T is not defined.

	* src/support/strfwd.h:
	Implement forward declarations in standard C++ way.
