Renaming an avpriv_ symbol to ff_ can only happen during a bump. So this patch is IMO ok. There's no warranty that whatever happens with SDR will happen before the next bump, so better remove as many exposed symbols as possible.

You are missing something here. With the symbols, i can fork libavdevice and add SDR support. Without the symbols, i cannot just do that. At least not cleanly Because i need to replace libavcodec too and i need to extend its ABI then. This makes this more messy. thx [...]

This reverts commits fd5aa93a37b3fa21195c6d7b22ef655124020e09 and cf00f60bab1f79213c274a6cd4357b32bd5c0101 ("avcodec/kbdwin: Support arbitrary sized windows"). The change in question has only been made for libavradio. in anticipation of merging it into the main tree. This has not happened, so this commit reverts the changes to kbdwin that are not used for anything else. In particular, these functions are no longer exported (as avpriv functions); notice that the fixed-point function has been exported despite having never been used outside of lavc.
