Subject: [PATCH] vnc-session: save message from "vnc-error" for "vnc-disconnected"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
"vnc-error" is always followed by "vnc-disconnected".
So save the error message and use it in "vnc-disconnected" callback.
"session-disconnected" already allows us to set a string
with details on why the disconnection happened.
This approach is also similar to the one in spice session
(GError is saved in virt_viewer_session_spice_channel_destroyed).

Subject: [PATCH] session: remove "session-error" signal
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This partially reverts commit de5cd71.
Problem with that commit is, that it practically renders
the "session-auth-*" signals from vnc session useless.
That's because gtk-vnc currently emits "vnc-error" before each
"vnc-auth-*" signal and the error callback in virt-viewer-app.c
calls virt_viewer_app_disconnected(), which in turn closes
the session.
As a consequence, virt-viewer never retries authentication
with vnc, it simply exits.
Since the last commit, vnc, similarly to spice, emits
"session-disconnected" with the appropriate error message. Thus
there's no need to maintain separate "session-error" signal
for now.
With vnc, this error message is shown to the user in a dialog,
if the disconnect happened during the init phase.
"session-auth-*" callbacks create their own dialogs, so
initialized must be set to TRUE to avoid having a dialog
displayed twice.

Subject: [PATCH] vnc-session: use g_signal_connect_object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If the VncDisplay emits a signal and the VirtViewerSessionVnc
instance is no longer valid, using the pointer inside one of the
callbacks can lead to segfault.
To prevent that, use g_signal_connect_object instead of
g_signal_connect.

Subject: [PATCH] build: fix build without gtk-vnc
Without gtk-vnc we get implicit function declaration for
VIRT_VIEWER_IS_SESSION_VNC. Introduced at 8bc91ac "session: remove
"session-error" signal" in 2021-02-18
As we are already using #ifdef here, I've also changed the ternary to
an if for clarity.
