With the way the runtime checks are currently set up, every single openh264 release, no matter how minor, is considered an ABI break and requires ffmpeg recompilation. This is unnecessarily strict because it doesn't allow downstream distributions to ship any openh264 bug fix version updates without breaking ffmpeg's openh264 support. Years ago, at the time when ffmpeg's openh264 support was merged, openh264 releases were done without a versioned soname (the library was just libopenh264.so, unversioned). Since then, starting with version 1.3.0, openh264 has started using versioned sonames and the intent has been to bump the soname every time there's a new release with an ABI change. This patch drops the exact version check and instead adds a minimum requirement on 1.3.0 to the configure script.
