avformat/avio: Don't use incompatible function pointer type for call

It is undefined behaviour even in cases where it works
(it works because it is only a const uint8_t* vs. uint8_t* difference).

Instead add a cbuf parameter to pass a const buffer (for writing)
as well as a parameter indicating whether we are reading or writing;
retry_transfer_wrapper() itself then uses the correct function
based upon this information.
