Could you clean this up (and QBool)?

Moreover, some of the QObject files are LGPL, some GPL. I bet this was
also not intended. But what was the idea behind the LGPL? Some libqmp which
can be used by closed source apps? Then better establish the required
license soon. Postponing this will only once require tedious author
questionings.

 Yes, it started with GPL and later we decided to move to LGPL, in
the (likely) case we move all this stuff to a library.

 I'll send patches.

I believe LGPL is needed for source apps that have GPLv2-incompatible
licensing.  E.g. GPLv3, Apache license, OpenSSL?  (I'm not sure exactly.)

And for those who want to keep their own apps BSD-like.

So lgpl libraries (like libvirt) can use libqmp.
