The attached patch adds two escape control sequences to the Cygwin Console:
* Show/Hide Cursor (DECTCEM)
* Set cursor style (DECSCUSR): block vs. underline cursor, or
arbitrary size (as an extension, using values > 4)

* fhandler.h (class dev_console): Flag for expanded control sequence.
* fhandler_console.cc (char_command): Supporting cursor style modes.
