       Restructure ifdefs
  4/5: Sort the response codes

       Copy uint16_t to wchar_t and use wcstombs to get char type
       for filename

  4/5: Fix compiler warnings and change default file permissions
  5/5: Fix file permissions

These patches implement write support for Qemu's MTP
emulation. Simple tests such as delete/move/edit/copy work ok.
Current issues/TODO:

 - File transfers > 4GB has not been tested and will probably not work
 - Some (or most) MTP clients don't advertise hidden files and folders (names
 that start with a .) even though iiuc Qemu MTP does advertise these files.
 This can confuse certain applications such as text editors or git.
 - Also related, file editors typically run fsync when saving. Depending on
 the MTP client, it may choose not to implement it (such as simple-mtpfs that 
 runs on top of fuse).
 - Needs more testing :)
