bug#16074: 24.3.50; enhancement request: Remove "pop" from command names & doc for `C-(u|x) C-SPC'

[Drew Adams]

See http://stackoverflow.com/a/20427244/729907.

The names and doc of the commands bound to `C-u C-SPC' and `C-x C-SPC'
are misleading, in that the commands do not really "pop" the marker
rings. They cycle the rings.  Markers are not removed from the rings
by such "popping".

Emacs uses the verb "cycle" for this kind of behavior elsewhere.  The
same terminology should be used here also.  We should rename
`pop-global-mark' and rephrase the doc.
