Consult clipboard, affect kill ring.  With existing emacs unpatched
mouse-yank-at-click, the kill-ring is affected (since the yank uses
current-kill which uses the interprogram-paste-function, potentially
/pushing onto/ kill ring.)

As I realised some users probably like middle-button inserted text
being subsequently available on the kill ring (it is after all current
emacs behaviour!), I allowed two ways for mouse-yank-at-click to work.
 If mouse-yank-at-click-source is yank, then a kill-ring yank (and
thereby current-kill and interprogram-paste-function) is used, and if
it is lightins, then
the interpgroam-lightins-function is used and the kill ring is not touched.


With the extended x-select-enable-clipboard and x-select-enable-primary,
it is possible to specify whether clipboard or primary or both should
be pulled in with (the X11 implementations of)
interprogram-paste-function or interprogram-lightins-function.

This allows both all historic emacs customizations and intended behaviour.
