Tom Tromey 7c043ba695 Add horizontal splitting to TUI layout 
This changes the TUI layout engine to add horizontal splitting.  Now,
windows can be side-by-side.

A horizontal split is defined using the "-horizontal" parameter to
"tui new-layout".

This also adds the first "winheight" test to the test suite.  One open
question is whether we want a new "winwidth" command, now that
horizontal layouts are possible.  This is easily done using the
generic layout code.
