Subject: [PATCH] Add log::stream_type typedef

This addition is useful when an explicit template instantiation of
operator<< is needed, for example, when logging from an ARM mode
function. Example usage:

template mtl::log::stream_type& mtl::log::stream_type::operator<<
<uint16_t>(uint16_t);

ARM_MODE void foo(int16_t x) {
	mtl::log::debug << x; // Without the explicit template
	instantiation, an ODR violation would occur.
}
