Glen Fernandes 6a218a5ef2 Merged revision(s) 81886,81887,81894,81905 from trunk: 
Use BOOST_NO_CXX11_RVALUE_REFERENCES and BOOST_NO_CXX11_VARIADIC_TEMPLATES instead of the legacy macros. Rename identifiers of detail utility functions.
........
Two detail utility functions identifier renaming reverted
........
Remove -fno-deduce-init-list for certain tests in Jamfile.v2
........
Correct call to init_list in make_shared and allocate_shared. Move g++ failing case into separate test to not mask other issues.
........
