Various give-backs

[Adrian Bunk <bunk@stusta.de>]

Packages in this list:
- source upload > 15 days ago
- no RC bugs in the package
- I cannot exclude the possibility that it might now build

I will do further actions (often filing RC bugs) for all packages that 
still fail after retrying.

gb libwebp_0.5.1-3 . armhf
gb yadifa_2.2.2-1 . ppc64el
gb leveldb_1.19-2 . armhf
gb gammaray_2.6.0-1 . armhf mips mipsel
gb r-cran-treescape_1.10.17-1 . i386 armel armhf
gb r-bioc-shortread_1.32.0-1 . armel
gb extlib_1.7.0-3 . amd64 arm64 armhf
gb ltt-control_2.8.2-2 . mips64el

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
