[aur-requests] Removal request: stxxl and stxxl-svn.

[1] https://aur.archlinux.org/packages/libstxxl/ [2] https://aur.archlinux.org/packages/stxxl/ [3] https://aur.archlinux.org/packages/stxxl-svn/ The latter two are orphaned, none has any votes. stxxl seems to be using git and not svn anymore http://stxxl.sourceforge.net/ -> https://github.com/stxxl/stxxl [2] has been submitted by the same person as [1], so I guess he decided to change the name. Their PKGBUILDs differ a bit though. Can we keep [1] and remove [2] and [3]?
