Allow to set the EOF timestamp. Also: doc/filters/testsrc*: specify the rounding of the duration option. The changes in the ref files are right. For filter-fps-down, the graph is testsrc2=r=7:d=3.5,fps=3. 3.5=24.5/7, so the EOF of testsrc2 will have PTS 25/7. 25/7=(10+5/7)/3, so the EOF PTS for fps should be 11/7, and the output should contain a frame at PTS 10. For filter-fps-up, the graph is testsrc2=r=3:d=2,fps=7, for filter-fps-up-round-down and filter-fps-up-round-up it is the same with explicit rounding options. But there is no rounding: testsrc2 produces exactly 6 frames and 2 seconds, fps converts it into exactly 14 frames. The tests should probably be adjusted to restore them to a useful coverage.
