configure, build: require at least Libav 0.7

Require versions of the Libav libraries corresponding to Libav release
0.7. These are:
libavutil   51.7.0
libavcodec  53.5.0
libavformat 53.2.0
libswscale   2.0.0
libpostproc 52.0.0

Also disable the fallback to simple header check if these libraries
could not be found with pkg-config; now compiling without pkg-config
support for these always requires explicitly setting --enable-libav
and any needed compiler/linker flags. The simple check would have let
compilation proceed even if a version mismatch was detected.
