25b3babe11 lavfi: always enable the scale filter and depend on sws. 
The scale filter is used for internal colorspace conversions, so it must
always be present.

ddce7dabd2 rtsp: avoid const warnings from strtol() call 
The strtol() interface makes it difficult to use with
const-qualified pointers.  With this change, although
the const is still lost, the compiler does not warn
about it.

58b2e0f0f2 vqavideo: return error if image size is not a multiple of block size 
The decoder assumes in various places that the image size
is a multiple of the block size, and there is no obvious
way to support odd sizes.  Bailing out early if the header
specifies a bad size avoids various errors later on.

Fixes CVE-2012-0947.
