Merge remote-tracking branch 'rdp/dshow_crossbar'
* rdp/dshow_crossbar:
dshow: fix docu escapes
dshow: some devices only list themselves under "Video sources" but actually have both video and audio output pins, so make the audio pins accessible by video source name.
dshow: add options for allowing filter popup configuration dialogs to be presented to the user
dshow: introduce support for crossbar [multiple input selectable] devices
dshow: drop initial audio packets with weird timestamps
dshow: use non deprecated api
dshow: miscellaneous tweaks
dshow: allow selecting devices by an alternative name (workaround for devices with symbols in them), allow specifying capture pins by name and alternative (unique) name
