When using a custom fullscreen display configuration, it's possible to
specify that e.g. a single screen should be fullscreen on client
monitor #4. Since we send down absolute positions and disable alignment
when all windows are in fullscreen, we can send configurations with a
very large offset to the top-left corner. This could result in the guest
trying to create a screen that was much larger than necessary. For
example when sending a configuration of 1280x1024+4240+0, the guest
would need to allocate a screen of size 5520x1024, which might fail if
video memory was too low. To avoid this issue, we shift all displays
so that the minimum X coordinate for all screens is at x=0, and the
minimum y coordinate is at y=0.
When trying to load ui files, we try to find the file in several directories.
If a file is not found in one directory, try to load it from the next directory.
However, if a file is found in a directory but we are not able to load it (e.g.
due to unsupported versions of glade used to generate it, etc), we should print
a warning to the terminal to help the developer debug the issue.
This is an unexpected failure (whereas not finding the file in that directory at
all is an 'expected' failure).
virt_viewer_util_load_ui() looks first in the current directory, and then looks
in the system data dirs for a ui file to load, but if you install virt-viewer in
a different prefix, it will load the system UI file rather than the one from the
install prefix. Try to load the ui file from pkgdatadir first.
ctrl_key_to_gtk_key() capitalizes all key names not explicitly specified in the
translation table. So 'end' becomes 'END', which is not a valid key name
according to GTK+. Un-comment out the 'end' item from the table and set it to
the properly capitalized key name ("End").
This allows users to specify e.g. "ctrl+alt+end" as a hotkey for
sending the secure attention sequence.

Use virt_viewer_signal_connect_object(), a copy of telepathy
utility function tp_g_signal_connect_object(). This function
will take care of removing signal handler if any of emitter or
attached object are destroyed.
The following patches will have this condition met, since there is no
longer 1-1 relation between channel and display. The channels can
continue to be around when some of the display are removed.
