[Xcb] Translating XkbApplyMappingChange() et al. to xcb-xkb

[Laércio de Sousa]

Thank you all for the reply!

Looking into libxkbcommon source code, I can see I can use
xcb_xkb_get_controls* stuff to get what I want. The remaining step to
complete my translation to XCB is to build a new XkbControlsRec struct from
the data available in xcb_xkb_get_controls_reply() returned struct. Is
there a trivial way to do this, or should I do it member to member? Ex:

ctrls->mk_dflt_btn = get_controls_reply->mouseKeysDfltBtn;
ctrls->enabled_ctrls = get_controls_reply->enabledControls;
etc.

NOTE: In my use case, this XkbControlsRec will be passed to
XkbDDXChangeControls(). Looking at this function definition, I can see it
only acesses members "enabled_ctrls" and "per_key_repeat" of passed
XkbControlsRec argument, so I think it will be enough to copy only these
members from xcb_xkb_get_controls_reply() returned struct.
