Stefan Hajnoczi 86635aa4e9 hostmem-file: add readonly=on|off option 
Let -object memory-backend-file work on read-only files when the
readonly=on option is given. This can be used to share the contents of a
file between multiple guests while preventing them from consuming
Copy-on-Write memory if guests dirty the pages, for example.
