avformat/aviobuf: Also return truncated buffer in avio_get_dyn_buf()
Two kinds of errors can happen when working with dynamic buffers: (Re)allocation errors or truncation errors (one has to truncate the buffer to a size of INT_MAX because avio_close_dyn_buf() and avio_get_dyn_buf() both return an int). Right now, avio_get_dyn_buf() returns an empty buffer in either case. But given that avio_get_dyn_buf() does not destroy the dynamic buffer, one can return the buffer in case of truncation and let the user check the error flags and decide for himself instead of hardcoding a single way to proceed in case of truncation. (This actually restores the behaviour from before commit 163bb9ac0af495a5cb95441bdb5c02170440d28c.) Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
