 Hello boost developer's

 I use managed_mapped_file for my project to create shared data structure
 and it is very good solution and simple to use. But i have a problem for
 big data & big query. I nead to have Huge page memory map file for better
 performance. I was check source code and see where is pass flag to mmap
 function in linux but no way to pass this flag from managed_mapped_file.

 I can to edit source to pass this argument but i hoop to this change added
 to boost source for all of developer use .

 source class hierarchy:
  managed_mapped_file
   basic_managed_mapped_file
    mfile_open_or_create
     managed_open_or_create_impl::priv_open_or_create
                                                     -> mapped_region
 (...,addr/*, map_options*/);

 source file hierarchy:
  managed_mapped_file.hpp
   managed_open_or_create_impl.hpp
    mapped_region.hpp
