[mythtv] seekable and streamable music from http servers in mythmusic

[Markus Schulz]

hello,
I've written a QHttpFilestream class which implements an QIODevice (QT4 
version) interface. With this interface you can stream and seek in 
music files from http servers.
I've done a short test with a quick hack in mythmusic (musicplayer.cpp):

if(m_currentFile.startsWith("http://"))
  m_input = new QHttpFilestream(m_currentFile);
else
  m_input = new QFile(m_currentFile);

and some further small hacks (building path of file from db-query) and 
can play now these manually entered music streams.

Now i would like to expand mythmusic with a new tree entry (beside "All 
playlists" and "Your music") called Streams.

Personally i would like to build a more generic way of building the tree 
below "Streams" with support for different backends, cause for myself 
i'm write one for a private service (code is unusable for others).

Now i need some input if others already working at similar things (found 
some pointers inside the mythmusic code) and whats the requirements to 
be generic enough to support other services?
