* Prevent malloc randomess from causing the header output routine to emit a GIF89 version string even when no GIF89 features are present. * Prevent malloc randomess from producing sporadic failures by causing sanity checks added in 5.1.2 to misfire. * Bulletproof gif2rgb against 0-height images. Addressed sf#78: Heap overflow in gif2rgb with images of size 0, also sf#82. * Remove unnecessary duplicate EGifClose() in gifcolor.c. Fixes sf#83 introduced in 5.1.2. * Fix sf#84: incorrect return of DGifSlurp(). - Add giflib-sf-88.patch to fix sf#88 OBS-URL: https://build.opensuse.org/package/show/devel:libraries:c_c++/giflib?expand=0&rev=37
