libavformat/avio: Add avio_get_dyn_buf function
This commit adds the avio_get_dyn_buf function which allows accessing
the
content of a DynBuffer without destroying it.
This is required in matroskaenc for preliminary writing (correct) mkv
headers.
Context for this change is fixing regression bug #5977.
