12975	Add map_options for managed_mapped_file (managed_open_or_create_impl_device_holder)	amirhakh@…	Ion Gaztañaga	"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
