New KIO::Connection

[Thiago Macieira]

I'd like to apply a patch very similar to the one attached to kdelibs in a 
week's time (i.e., not tomorrow). I am still testing a couple of things 
and some bugs may show up.

I have redesigned KIO::Connection and adapted KIO::Slave, 
KIO::SlaveInterface and klauncher to the new API. The class is exported, 
but is private, so there should be no impact at all in any application. I 
have only found offending code in kio_file, which I will need to fix.

The new implementation completely does away with file descriptors. It uses 
KLocalSocket for now as its only backend, but I want to write at least 
one more, based on D-Bus. The main reason for this change is to make sure 
we can get rid of K3Network and, therefore, support more platforms.

In the process of developing it, I realised that KIO::SlaveInterface was 
an abstraction for KIO::Slave, but right now it's not possible to have 
one without the other, and it's the abstraction that imposes the format 
of int+QByteArray for as a communication method. It should be possible to 
merge them into a single class.
