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.
Some cleanups.

Make sure the cur_level.bytes is updated after we change the writing_pos or the
max_reading_pos.
Refactor get_free_space()

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.

0a84d81901 queue2: fix merging of ranges
When we merge two ranges, don't updata the current range writing_pos with
whereever we were writing earlier in the merged range.  Spotted by bilboed.

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.

db172aaa6f queue2: when EOS we know the duration
When we are EOS, we don't need to do an upstream query for the duration in bytes
because we already know it is the offset of the last written byte.

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.

1a50186630 queue2: fix printf format
Cast the variable to gint to conform to the printf format used.
It is casted rather than changing the format because the
message is created with a cast to gint too.

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.
