[Qemu-devel] [PATCH 1/1][RESEND] v2: Fix text console size/resize when using curses

[Ryan Harper <ryanh@us.ibm.com>]

v2: drop initial size adjustment, not needed.

Resize events fail to ensure that both the text console and curses display areas
are the same size; this causes broken output like:

QEMU 0.9.1 monitor - type 'help' for more information
                    (qemu)
                                            (qemu)
                                                                (qemu)

To fix this, ensure that the display width and the text area width are sync for
text consoles on refresh; also force a resize event whenever we invalidate the
text console.
