Alex Turbov 3fdd8db3aa Refactor: Avoid std::endl where it's not necessary (part 1) ...

The `std::endl` manupulator, except inserting `\n` character, also
performs `os.flush()`, which may leads to undesired effects (like
disk I/O in the middle of forming data strings). For the
`std::stringstream` it also has no meaning.
