* Added Directory::CreateFile() which can be implemented by file systems to

support file creation.
* Extended open() and open_from() to support O_CREAT to create files.
  open_from() has got an optional "permissions" parameter for that purpose.
* Fixed errno. It would crash when being used. Also changed the POSIX functions
  to return their error code via errno as expected.
* Added writev().
* FAT file system:
  - Added support for reading long file names.
  - Added support for creating files (8.3 name only) and writing to them.
  - Enabled scanning partitions with it.
* Boot loader menu:
  - Enabled the "Reboot" menu item unconditionally.
  - Added "Save syslog from previous session" menu item to the debug menu.
    Currently saving the syslog to FAT32 volumes is supported.
