xfree86/parser: annotate xf86ConfigSymTabRec as constant data
Add the const notation to all the static storage as well as the
functions that use it - xf86getToken(), xf86getSubTokenWithTab(),
StringToToken() and xf86getStringToken().

xfree86: Make xf86SetDDCproperties work more than once (v2)
We can call this more than once via xf86OutputSetEDID since hotplug is
actually a thing in RANDR 1.2, but xf86RegisterRootWindowProperty merely
adds the data to a list to be applied to the root at CreateWindow time,
so calls past the first (for a given screen) would have no effect until
server regen.
Once we've initialised pScrn->pScreen is filled in, so we can just set
the property directly.
