c4fbff50df mssdemux: fix setting codec_data when using WaveFormatEx 
When using WaveFormatEx the actual codec private data is at the end of
the wav header structure, after the cbSize field, see for example the
notes at http://wiki.multimedia.cx/index.php?title=WAVEFORMATEX

The previous code was erroneously passing the whole WAVEFORMATEX
structure as codec_data.

The smoothstreaming specifications[1,2,3] always mention WAVEFORMATEX
and never smaller structures like WAVEFORMAT or PCMWAVEFORMAT, so the
buffer can assumed to be at least 18 bytes and always consuming the wav
header gives the (possibly empty) codec private data.

fe77ee47c9 mssdemux: also consider /manifest 
The spec says /Manifest, but /manifest is easily found on some
services, so handle that, too.

1b1332cb6d mssdemux: use gst_data_queue_push_force for adding events to queue 
This prevents locking on startup when a stream only has a single buffer
for one of the streams and mssdemux decides to push an EOS event right
after it.

750137c4be mssdemux: fix wma pro caps creation 
WmaPro is actually wmaversion 3, and can also be found by the
WMAP fourcc.

Some manifests also contain the block_align field as "PacketSize"
in the audio track description, the libav decoders require it
to be present in caps.

27d726fbfa mssdemux: parse block_align, channels and rate from waveformatex if possible 
wma v2 expects block_align, channels and rate fields set to its caps.
This isn't present direclty on the manifests, so mssdemux should parse
it from the waveformatex structure

43fea50c8a smoothstreaming: pass width, height, channels and rate as integer 
g_ascii_strtoull() returns a long long integer, but we need to
pass a normal int to gst_structure_set() for fields of G_TYPE_INT,
so cast appropriately.

safer

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.
