* missing make_pair() for r-value refs

hello guys!

the `make_pair()` for r-value refs is required for r-value, otherwise `non-copyable` but `movable` can be constructed.


thanks!

* fix for prev commit

conditional support for r-values was fixed

* the test case was added

* fix for prev commit

* Update Jamfile

* one more fix for Jamfile

* the forgotten r-value ctor was added

* ah, they should be conditional
