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

dec12cb2b8 queue2: Fix a special case during range management
When a range contained no data, if it was new or newly empty, it would

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
One must not affect the values of the current range based on a read
request before the correct range is activated.

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.

178821aace queue2: various ring buffer fixes
- 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

2057cf6d79 queue2: download mode; prevent range corruption due to race
Current range was being updated in the thread performing seek, but as
no locks were kept for a short section, data flow could resume before
current range updated, so data for the new range would be accepted as
from the previous range.

Rather, range should be updated in serialized manner based on
newsegment event.

15141b3954 queue2: don't wait for data when EOS
When in download mode and we need to provide data for an offset that we don't
have, also perform a seek to the requested location when we are EOS. The reason
why we shouldn't wait for more data is because after EOS, there simply will be
no more data and we end up waiting forever.

11304c1257 queue2: implement flushing in download buffering
Maintain a separate variable to control src and sink flowreturn values so that
we can unlock the src part without shutting down the sink part.
Add flushing for upstream pull based elements that unblocks our getrange
function. This implements seeking when blocking for more data.
Add some arbitrary threshold before attempting a seek. Add a FIXME for this
because we need to find a sensible threshold based on the input rate.

245089c9bd queue2: avoid crashing due to negative percent
queue2 would crash when using small buffer sizes because
it would overflow when calculating the percentage, resulting
in the buffering GstMessage not being created and trying to be
used. This patch uses a gint64 instead of a gint to do the
percentage math, making it harder to overflow.
