Update gentoo to 0.11.56.
Patch provided by Martin Wilke via PR 34341.

0.11.56
* Fixed buglet that caused copying of protection bits to always
  be a fatal error, regardless of the "Ignore Failure to Copy
  Attributes" option setting.
* Fixed a silly case of errno "leaking" out of the window title
  setting code (which needs to mess with NLS). This had gentoo
  break totally (couldn't even copy files) on Ubuntu. Big thanks
  to M. Williams for letting me ssh and vnc to his Ubuntu box so
  I could hunt this one down.
* Rewrote core of regular file copying function. It seems when
  writing to a Samba-mounted (network) share, write() doesn't
  like large buffer sizes. So we loop to empty the buffer of read
  data, doing as many writes() per read() as is necessary. Odd.
* Fixed bug that made it impossible to use RenameSeq on volumes
  using a VFAT filesystem. This was due to the use of invalid
  characters in temporary filenames.
* Made RenameSeq's start value settable through a spinbutton in
  the dialog, rather than a plain entry. Faster small changes.
* Added a new page to the RenameRE dialog, 'Map', which does
  simple character mappings on filenames. Also supports removing
  a set of character (think 'tr', applied twice).
* Added information about missing options (--locale-info, --run)
  to the manual page.
