lavfi: remove 'opaque' parameter from AVFilter.init()
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

lavfi: remove request/poll and drawing functions from public API on next bump
They are only useful inside filters and we don't allow user filters for
now.

vf_boxblur: fix memleak
As the filter uses the default start frame, the cleanup done by the
default end frame is needed.

Mark AVFilterPad[] compound literals as const.
GCC 4.6.2 at least still seems to fail to put them in .rodata though,
see also http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37303

* support to gray format
* support to yuva420p format
* parametric luma/chroma/alpha radius
* consistency check on the radius values, avoid crashes with invalid values

vf_boxblur: fix out-of-buffer access when h > w
Increase size of the private temporary buffers from w to FFMAX(w, h),
indeed they are used also for blurring vertical lines with length 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.
