[PATCH weston 06/14] weston_xkb_info: Cache all modifier indices for X11

[Daniel Stone]

X11 has a set of eight modifiers which we want to represent.  Cache
their indices when we create a weston_xkb_info, so we can use this from
compositor-x11 to keep the state synchronised exactly between the host X
server and a nested Weston instance.
