When there is a sink inside a bin, the SINK flag is set on the bin. When we are
trying to iterate the source elements, also include the bins with the SINK flag
because they could also contain source elements, in which case they are also a
source.
This solves the case where sending an EOS to a pipeline didn't get dispatched to
all source elements.
See #625597
gst_element_link_many does some magic and creates ghostpads
if needed, but it didn't set the newly created ghostpad to
active if needed. This patch fixes it.

- Set reading_pos correctly in _create_read ()
- Seek to data if it is further than QUEUE_MAX_BYTES (queue) -
cur_level.bytes away. This should avoid a situation where the ring
buffer is full but the data offset from which we shall read is not in
the ring buffer.
- Only update the max_reading_pos to a lower value to protect data when
necessary
- Always signal an ADD in _locked_enqueue () so that an EOS unlocks the
reader
- More useful debug output
update_buffering () needs to be called every time we write to the ring
buffer so that applications don't get stuck waiting for a 100% buffered
message while queue2 is waiting for space
_create_write () must only be called for temp file/ring buffer cases
Cached data could have been overwritten so it is now protected until
it is read. Similarly data was overread as _have_data () was always
looking for the originally requested data even if part of it had been
read already.
Use cur_level.bytes to see how much space is free in the ringbuffer.
Simplyfy the write function, avoid taking subbuffers, move waiting for free
space in one spot, use simply counter to write data of a buffer.
- make _get_range () emit the del signal once a buffer has been read
- use do {} while (); for wait code as queue is locked and no data could
have been read in the mean time so it makes no sense to check before
waiting
- make _is_filled () more robust
This is not really necessary here because everything is
initialized from gst_init() already but using G_DEFINE_TYPE()
removes some copy&paste boilerplate code.
