preserve text on Windows terminal resize (bug #41893; patch #8532) * QWinTerminalImpl.h, QWinTerminalImpl.cpp (QConsolePrivate::updateConsoleSize): Don't shrink the size of the console buffer. Store the terminal size in the environment. Force the command line editor (usually readline) to notice the change in screen size as soon as possible. (QWinTerminalImpl::QWinTerminalImpl): Connect set_screen_size_signal with parent set_screen_size slot. (QWinTerminalImpl::set_screen_size_signal): New signal. * main-window.h, main-window.cc (main_window::int_pair): New typedef. (main_window::set_screen_size_callback): New callback function. (main_window::set_screen_size): New slot. * sysdep.cc (w32_init): New function. Tell command_editor to prefer environment variables for window size. (MINGW_init, MSVC_init): Call w32_init. (QWinTerminalImpl::setSize): Emit set_screen_size_signal.
