Review request for mesos, Benjamin Hindman, haosdent huang, James Peach, and
Michael Park.
Bugs: MESOS-7713
https://issues.apache.org/jira/browse/MESOS-7713
Repository: mesos
Description (updated)
-------
This reduces number of copies made for each parameter in a code like this:
future.then(defer(pid, &SomeProcess::someMethod, param1, param2));
For the objects that do not support move semantics (e.g. protobuf messages),
number of copies is reduced from 8-10 to 6. If move semantics is supported,
then number of copies is reduced from 6-7 to 1 if parameter is passed with
std::move, or 2 otherwise.

Testing
-------
make check
Number of copies was checked by using defer to subscribe process for Future
callbacks, and passing parameters that count number of copies made.
Thanks,
