vf_boxblur: fix out-of-buffer access when h > w
...
Increase size of the private temporary buffers from w to FFMAX(w, h),

vf_boxblur: prefer the name "len" over "w" in the blur routines
...
Make more clear the meaning of the variables. They specify the length
of a (vertical or horizontal) line rather than a width.
Less confusing.
