Karl Wiberg cefc46517e RTC_LOG_* macros: Implement argument passing with a single variadic call
Instead of making multiple calls to the std::stringstream << operator,
collect all the arguments and make a single printf-like variadic call
under the hood.

Besides reducing our reliance on iostreams, this makes each RTC_LOG_*
call site smaller; in aggregate, this reduces the size of
libjingle_peerconnection_so.so by 28-32 kB.

A quick benchmark indicates that this change makes log statements
a few percent slower.
