ae7d938842 mssdemux: PlayReady WRM parsing support
If the manifest has a ProtectionHeader node then parse it and emit
protection events according to the specified protection SystemID.

8c49c79d7e mssdemux: add live support
Implement the functions of adaptivedemux to have live support
enabled. This allows mssdemux to refresh the Manifest periodically

Set void as the return and remove error handling as it could
never fail

255eb4b161 mssdemux: use streams bitrate individually
connection setup times seem to matter when measuring the download
rate of different streams. Streams with longer fragments have a
*relatively* lower connection setup time and achieve higher bitrates.

Using the average seems unfair here, so use each stream's measured bitrate
to select its best quality option.

aa1713068a mssdemux: implement live streams handling
Live streams force the demuxer to keep reloading the Manifest from
time to time, as the new fragments are being added as they are recorded.
The demuxer should also try to keep up and detect when it had to skip
fragments, marking the discont flag when that happens.

Curiously, the spec doesn't seem to mention when/how a live stream is supposed
to end, so keep trying downloads until the demuxer errors out.

b9aec0ad0d mssdemux: add connection-speed property
This speed limits the maximum bitrate of streams. Currently it
is only read when starting the pipeline, but it should be used
for switching bitrates during playback to adapt to network
changes.

4b6900999a mssdemux: add an 'active' flag to manifest stream
mssdemux should set the streams it has exposed as active so that
the manifest won't use the non-active streams to compute total bitrates
or providing fragments

9b3f67c5b0 mssdemux: set timestamp and duration to fragment buffers
We can get those from the manifest and helps downstream to know
the fragment start time after a seeking operation

cb7e3d1f3b mssdemux: initial implementation of seek event handling
Adds basic handling for seek in time events. Needs to cooperate
with the downstream qtdemux so that it forwards the seeks and
the corresponding newsegments

33d872916b mssdemux: handle src pad queries fir duration and latency
Add a src pad query handler to get the duration from the manifest
and report it upstream.

Also adds a simple handler for latency queries

3f15c9b05a mssdemux: add timescale to the caps
This is important for downstream to properly timestamp the samples

The default value is 10000000, but this can be set in the stream
or at the top-level manifest entry

ca4e5c34cb smoothstreaming: refactor structure names and implement url fetching
Use shorter names for the MSS manifest helper structure and functions.

Also continues the implementation of the stream fetching and pushing loop.
Now it uses the base url correctly and already fetches and pushes the fragments
downstream

5291985efe mssdemux: pad exposing initial implementation
Does some basic parsing of the stream caps and adds a pad for
each stream detected in the manifest

72b05c0051 mssdemux: add manifest parsing
Continued implementing:
1) parse the manifest with libxml2
2) detect stream types

95e87fbee9 smoothstreaming: stubs for mssdemux
Just the stubs for mssdemux element.
Also add some useful code from hlsdemux that we intend to reuse
