stream: change STREAM_CTRL_GET_SIZE argument type to uint64_t

Update endpos each time libavformat asks for it.

Fixes playback of still downloading files to not stop before we
really reached the end.

Change STREAM_CTRL_GET_SIZE argument type from off_t to
uint64_t.
Also fix the incorrect type of the uint64_res variable.

Note: also merges the "forgotten" cache support from r35107.
