Fix switching between normal and alternate screen

xterm's documented behavior for ESC [ ? 1049 h is "Save cursor as in
DECSC and use Alternate Screen Buffer, clearing it first."  Similarly,
ESC [ ? 1049 l is documented to clear the screen and do DECRC as well as
swapping to the normal buffer (which screen should be cleared is
unclear from the text, but behavior suggests that it should be the
alternate screen).  As of now, though, we treat these escape sequences
as simple toggles between the normal and alternate screens.

Implement clearing the alternate screen when switching into it, and
saving and restoring of the cursor; as we don't provide a method to
switch to the alternate screen without clearing it first, it's
unnecessary to clear the alternate screen when leaving it.  (The xterm
documentation suggests that ESC [ ? 47 h (and possibly ESC [ ? 1047 h as
well) should enter the alternate screen without clearing it, but GNU
screen -- the terminal we claim to be by default -- doesn't appear to
implement this distinction between those sequences.)
