 INITARGS was a hardcoded define to void.  Since knowing the function
 signature for your extensions is kinda useful, just replace it with a
 hardcoded void, but leave the define there for API compatibility.

 This undoes the workaround for X.org bug #964, which was an Xprintism.

 There's no sense verifying that we can create the lock file and then
 ignoring the return value from write.

    Refactor common code from XAddHost & XRemoveHost into single function

    On the Xlib side, the only real difference is the mode flag we send
    to the server with the address, so just make that an argument to the
    function with the common code for packing the address into the request.

    (Aside from labels, gcc 4.7.2 generates identical code before & after
     this change due to inlining, verified via diff of gcc -S output.)

 "An experimental pseudocolor emulation layer.  Not fully completed,
 currently only works for 16bpp."  That was almost four years ago.
 It still doesn't work, only one driver even attempts to use it, it
 contains an ad-hoc implementation of damage, and should really be
 done up in Composite now anyway.
