Some atom related optimizations
We often get a strdup'd string, just to pass it over the atom_intern and
then immediately free it. But atom_intern then strdup's it again (if
it's not interned already); so instead we can have the interning "steal"
the memory instead of allocing a new one and freeing the old one. This
is done by a new xkb_atom_steal function.
It also turns out, that every time we strdup an atom, we don't actually
modify it afterwards. Since we are guaranteed that the atom table will
live as long as the context, we can just use xkb_atom_text instead. This
removes a some more dynamic allocations.
For this change we had to remove the ability to append two strings, e.g.
"foo" + "bar" -> "foobar"
which is only possible with string literals. This is unused and quite
useless for our purposes.
xkb_atom_strdup is left unused, as it may still be useful.
