Fix compilation of standalone filters after 3527afd9ec710ab601e25319dddeb482f5001362.

Also move the workaround into its own project.
Lite builds: Fix a minor inconsistency regarding the output directory.

Lite debug builds use "mpc-hc_x??_Debug Lite" while release builds always used "mpc-hc_x??" for both normal and lite builds.
Updated LAV Filters to 0.60.1-65-ddc46e6 (custom build based on 0.60.1-60-445393e)

Important change:
 - LAV Video: Fix artifacts on some H264 streams with both software and DXVA decoding (reported upstream as https://trac.ffmpeg.org/ticket/3386).
DVBSub: Fix a stupid parsing bug leading to the wrong page being used.

There is absolutely no reason to copy the region list from the previous page since that means we would just be displaying the old page again instead of the updated one...
DVBSub: Ensure no region is lost to avoid partially rendered subs.

Some regions can be received before they are actually needed. We use to ignore them but we shouldn't have.
