Subject: Use emplace_back(params) instead of push_back(type(params))
This is C++11: you can convert
std::vector<complextype> vec;
vec.push_back(complextype(foo, bar, baz));
by
std::vector<complextype> vec;
vec.emplace_back(foo, bar, baz);
which saves one unnecessary copy.
This mostly happened in rpc code.
The automated clang-tidy check failed miserably, so most of this was
done by hand.
