b1fac8c781 hlsdemux: Fix decrypting fragments
Only reset the decryption engine on the first buffer of a fragment,
not again for the second buffer.  This fixes corrupting the second
buffer of a fragment.

1e795ccce1 hlsdemux: Propagate error messages from the source element up in the hierarchy
Instead of inventing our own generic error strings which are mostly useless.

aea14053d1 hlsdemux: Always flush the internal proxy pads before downloading
hlsdemux can't rely on the source to push flushes on a seek on ready
as that might not make sense. So always resort to flushing the
internal proxy pads by pushing flush events from the source's src pad.

Also as the seeking is not required anymore, only seek if there is
really a byte range to be used. And store a ref to the source's
src pad to avoid doing get_static_pad for every fragment.

4431388cab hlsdemux: handle errors from internal source
Set up a message handling function to catch errors from the internal
source and store the last return code to identify error situations
when returning from a fragment download.

Also moves the duration increase to after the download when we
know if it was successful or not

f16560c520 hlsdemux: Improve pad switching conditions
When using the internal source, hlsdemux doesn't know the caps of
the input before adding the pad, so remove the arguments that would
use that as it is always NULL.

And use an specific flag to signal when a pad switch is required.
Using the discont flag is a bad idea now because when a fragment
download fails it will lead to exposing a pad group without any
data, causing decodebin to abort.

ff395a7565 hlsdemux: Track fragments duration
When receving EOS from the internal src, increase the current positon
by the fragment duration to allow correct restoring of download position
if the bitrate changes

cc033c7ca0 hlsdemux: enable download bitrate measure
Measure the download bitrate to be able to select
the best playlist.

As the buffers are directly pushed downstream and it
might block. The time is only measured from the download
until the pad push and it is started again after the push
returns.

c93c222786 hlsdemux: re-enable decryption after uridownloader removal
Now the decryption is done buffer by buffer instead of on the
whole fragment at once. As it expects multiples of 16 bytes a
GstAdapter was added to properly chunk the buffers.

Also the last buffer must be resized depending on the value of the
last byte of the fragment, so hlsdemux always keeps a pending buffer
as it doesn't know if it is the last one yet

3611759557 hlsdemux: replace uridownloader with a GstElement
The GstElement is directly linked into a ghost pad and
its buffers are pushed as received downstream. This way the
buffers are small enough and not a whole fragment that usually
causes extra latency and makes buffering harder

It's not really correct yet for seeks but better than what
we had before.

a51116add3 hlsdemux: Refactor threading and downloading
We now download fragments as fast as possible and push them downstream
while another thread is just responsible for updating live playlists
every now and then.

This simplifies the code a lot and together with the new buffering
mode for adaptive streams in multiqueue makes streams start much faster.

Also simplify threading a bit and hopefully make the GstTask usage safer.
