   [platform] Allow to memory-map empty files
   
   This current fails, since {mmap} fails with EINVAL for empty mappings.
   The destructor already has special handling for a {nullptr} mapping, so
   we can just use {nullptr} for empty files. We get a similar error on
   windows, and can fix it the same way.
   
   On order to make presubmit checks happy, we have to skip copyright
   checking and checking for terminating newlines for empty files.
