#4230: [Patch] Fix missing/broken friend function definitions in class templates

Milestone:  Boost 1.43.0  |   Component:  interprocess
  Version:  Boost 1.44.0  |    Severity:  Problem     
 Keywords:                |  
--------------------------+-------------------------------------------------
 We turned on better checking for in-class friend function definitions in
 Clang, instantiating them when the class templates containing those
 friends are instantiated (see C++98/03 [temp.friend]p5). This found some
 breakage in the Interprocess library, where an obvious "operator==" is
 missing (it's used via an in-class friend function definition) and a
 swap() function defined as an in-class friend function could never be
 compiled.

 I've attached a patch that fixes both problems.
