8bf4c1e1a8 queue2: don't read beyond the end of file upstream in pull mode
... which could lead to a premature eos being reported downstream,
rather than a successful partial read which would result when
performed directly on e.g. basesrc.

e14c133587 queue2: properly identity dequeued event as such

8f12a5e7cd queue2: Only call update_buffering if needed.
update_buffering is so big it will never be inlined (and shouldn't),
we therefore move the check outside of it.

8a79c1aa98 queue2: Avoid useless segment_to_running_time() calculations.
* Cache src and sink time
* Use a boolean to known whether src/sink time needs to be recalculated

Avoids 50% of calls to gst_segment_to_running_time()

e554c7a1f6 queue2: Remove redundant variable
Other than saving an immense amount of 4 bytes of memory this
prevents clang from complaining and keeps the ring buffer state
in a single variable instead of two.

ce35fb79da queue2: don't send seeks beyond the end of the file upstream in pull mode
If downstream is operating in pull mode, short-circuit any pulls beyond
the end of the file and return FLOW_UNEXPECTED immediately instead of
sending a seek beyond the end of the file upstream, since this might
confuse upstream elements (and/or http servers, for example). Fixes
playback of apple trailers in totem and youtube/html5 clips in
WebkitGTK+.

e3176a31e9 queue2: always update buffering status
Update the buffering status even when we are not using a queue so that EOS can

dec12cb2b8 queue2: Fix a special case during range management

be mishandled if it were the current range.

414911b90a queue2: fix locking around init_ranges
This fixes a segfault where the ready to paused state change causes
freeing and allocation of new ranges while another thread is trying to
use them.

0182c0d88b queue2: More ring buffer fixes
- 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

c78996a313 queue2: ring buffer fixes

602f4774c7 queue2: Fix bugs
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

e29cca10a4 queue2: merge write buffer functions and fix bugs
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.

695da33ef5 queue2: cleanup write_to_ring_buffer
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.

abc9ab1747 queue2: cleanups
Add a macro to get the max size of the queue in bytes, which depends on the
max_level.bytes and the ring_buffer_max_size.
