When QIOChannels were introduced in 666a3af9, the feature bits were
already defined shifted. However, when using them, the code was shifting
them again. The incorrect use was consistent until 74b6ce43, where
QIO_CHANNEL_FEATURE_LISTEN was defined shifted but tested unshifted.
This patch changes the definition to be unshifted and fixes the
incorrect usage introduced on 74b6ce43.

Parts of the code have been testing QIOChannel features directly with a
logical AND. This patch makes it all consistent by using the
qio_channel_has_feature() function to test if a feature is present.

Testing QIOChannel feature support can be done with a helper called
qio_channel_has_feature(). Setting feature support, however, was
done manually with a logical OR. This patch introduces a new helper
called qio_channel_set_feature() and makes use of it where applicable.

This patch adds a test to verify that the QIOChannel framework will not
unlink a filesystem unix socket unless the _FEATURE_LISTEN bit is set.
Due to a bug introduced in 74b6ce43, the framework would unlink the
entry if the _FEATURE_SHUTDOWN bit was set, regardless of the presence
of _FEATURE_LISTEN.

The GSource object has ability to have a name, which is useful
when debugging performance problems with the mainloop event
callbacks that take too long. By associating a name with a
QIOChannel object, we can then set the name on any GSource
associated with the channel.

The main loop creates two generic sources for the AIO
and IO handler systems.

Oh interesting - I've just seen my Travis CI build check also failed
over night on OS-X.
I wonder if OS-X automatically deletes UNIX non-abstract sockets paths
on the filesystem when the socket FD is closed ?!?!

Daniel

The assertion is the other way round, isn't it? It's trying to
assert that the path doesn't exist, but in fact it does
(and it's still lying around in my working tree after the
test failure).

Oooooh, I'm looking at the wrong test case. I was assuming it was the
newly added test case that failed, whereas it is the original test
case we've regressd on.

Ok, the problem is that SO_ACCEPTCONN is not working on OS-X. Googling
it seems this is likely broken on some versions of BSD too, so I'll
rework the patch to avoid that function.
