[PATCH xproto] Add XF86XK_Keyboard

I did indeed see the 'big comment' while making the change, but when I 
looked for a good place in keysymdef.h to put this key nothing obvious
seemed like the right place. The "Misc functions" group doesn't seem to
have any values left to use. Maybe a new group in the "XK_XKB_KEYS"
section?

While discussing this issue (on IRC) with Daniel Stone and a few others
it was pointed out that the intention to not add symbols toXF86keysym.h
  might be a relict from era where XFree86 was still "more active" (to
put it nicely). So still in doubt after all the discussions I decided
to put it in XF86keysym.h was the easiest and despite "the big comment"
maybe still the best option; mainly I wanted to get advice where to
exactly put this keysym (and future ones as there might be more like
this key in the near future since there are quite a few umapped input
key events).

Sorry, I meant to add all this to a cover letter to the initial patch,
somehow that got swallowed.

Thanks,
CK
