This makes it so that "on_connected" always gets called first.
Since accepted sockets are connected before construction, they have
to manually set CSocket::m_connected.
Both overloads should know how to set up a notifier callback in case
we get EINPROGRESS from connect().
It might be even better to merge the connect() overloads into a single
function..
The Inspector app quickly exposes crappy flat object hiearchies without
parent/child relationships. This is one of many commits that improves
the situation by making parent/child CObject relationships explicit.
We're going to be using dedicated server socket classes instead.
This was only implemented for CLocalSocket, and clients have been switched
over to using CLocalServer.
If custom I/O is being done outside CIODevice, we need a way to force blocking sometimes.
This also fixes the default of CLocalSocket to be non-blocking, the same
as CTCPSocket.
* Add a LibAudio, and move WAV file parsing there (via AWavFile and AWavLoader)
* Add CLocalSocket, and CSocket::connect() variant for local address types.
We make some small use of this in WindowServer (as that's where we
modelled it from), but don't get too invasive as this PR is already
quite large, and the WS I/O is a bit carefully done
* Add an AClientConnection which will eventually be used to talk to
AudioServer (and make use of it in Piano, though right now it really
doesn't do anything except connect, using our new CLocalSocket...)
