Merge branch 'nested' - nested structs/classes support

* nested:
  Deprecation of the 'nestedworkaround' feature
  Ensure -c++out is not used with -c++
  Add missing header to new source file
  Nested C class setters restored in c++out mode for Octave
  Classprefix fixed after private nested classes some comments and spaces added
  Fix template partial specialization detection
  Minor tweaks in Swig_feature_set
  Swig_offset_string moved to misc.c
  nested private classes are discarded while parsing nested relate functions are moved to nested.cxx and renamed accordingly
  out-of-scope template definitions fixed nested_private test disabled again
  fixed out-of-scope nested class definitions, added a test enabled nested C structs assignment (still disabled for Octave), added Java runtime test fixed nested_private test case for Java & C#
  Testcase of private nested class usage causing segfault
  C nested struct passed by value example
  Add in Travis testing for nested branch
  Add C++ nested class example
  Minor code improvements
  Cosmetics/code beautification of nested class support
  Nested classes support
