xcb + xcb-xkb + xkbcommon as a proper replacement for Xlib + xkbfile for
keyboard support.

The X11 support must be enabled with --enable-x11 for now.

modifications, remote clients, etc., so is not a proper solution in

expr: split expression types and allocate them separately

Currently, we have one ExprDef type, which contains a tagged union with
the value of all expression types. Turns out, this union is quite
wasteful memory-wise. Instead, create separate types for all expressions
(e.g ExprBinary, ExprInteger) which embed the common fields
(ExprCommon), and malloc them per their size; ExprDef then becomes a
union of all these types, but is just used as a generic pointer.

[Instead of making ExprDef a union, another option is to use
ExprCommon as the generic pointer type and then do up-castings, like we
do with ParseCommon. But this makes the code much uglier.]

The diff is mostly straightforward mechanical adaptations. It could have
been much smaller with the help of C11 anonymous structs (which were

little effort, we should.

*any* map is better, and the parser is also a bit smarter then old
xkbcomp and doesn't parse many useless maps. So there's no discernible
