Make requested console reports work

cf https://cygwin.com/ml/cygwin-patches/2012-q3/msg00019.html

This enables the following ESC sequences:
ESC[c sends primary device attributes
ESC[>c sends secondary device attributes
ESC[6n sends cursor position report

    * fhandler.h (class dev_console): Add console read-ahead buffer.
    (class fhandler_console): Add peek function for it (for select).
    * fhandler_console.cc (fhandler_console::setup): Init buffer.
    (fhandler_console::read): Check console read-aheader buffer.
    (fhandler_console::char_command): Put responses to terminal
    requests (device status and cursor position reports) into
    common console buffer (shared between CONOUT/CONIN)
    instead of fhandler buffer (separated).
    * select.cc (peek_console): Check console read-ahead buffer.
