In base/logging.h, the accessor stream() returns a reference to a
std::ostream instance.
However, <ostream> is never included.
Some STL may include it via strstream but not all of them (e.g Android)
Also manually forward declare std::ostream does not work with all the
compilers but including <iosfwd> may work if you don't want to include
<ostream> directly.
