Nicolas Pitre 5eb608319b vt: save/restore unicode screen buffer for alternate screen 
The alternate screen support added by commit 23743ba647 ("vt: add
support for smput/rmput escape codes") only saves and restores the
regular screen buffer (vc_origin), but completely ignores the corresponding
unicode screen buffer (vc_uni_lines) creating a messed-up display.

Add vc_saved_uni_lines to save the unicode screen buffer when entering
the alternate screen, and restore it when leaving. Also ensure proper
cleanup in reset_terminal() and vc_deallocate().

Fixes: 23743ba647 ("vt: add support for smput/rmput escape codes")
