Bochs/bochs/gui/term.cc
Volker Ruppert 92b06b9ebf - new function get_clipboard_text() for GUI specific clipboard handling
GUI specific paste functions for X11 and WIN32 in paste_handler() moved to
  the new function
- get_clipboard_text() prepared for other GUIs
- set_clipboard_text() has now a return value (0 = failed or not implemented)
- use portable code in copy_handler() if set_clipboard_text() fails
- snapshot_handler() prepared for adding a file dialog call
- writing snapshot file in binary mode (LF->CRLF conversion already done)
