[Lxde-list] LXMusic Hack, Speed up with direct SQLite access

[PCMan <pcm...@gm...>]

OK,
To solve the previously addressed problems, I add a new branch sqlite
to experiment with new idea.s
This time I directly access the medialib file of xmms2 with sqlite3,
and fonud it's much faster.
So the problem is quite apparantly caused by poor IPC roundtrip design.
However, the sqlite database is not in good format, either. So the
query became very slow.
With this sqlite branch, it gets reasonable speed while doesn't
require additional caching mechanism or additional library. (sqlite3
is already required by xmms2)

I know that it's better fixed in upstream server code, but from the
git log of their code, the new database format code is not updated for
quite a long time and we don't know when will xmms2 has next new
release. So, let's use our own hacks for now before they fix it.

Please test and give some opinions.
