[ekiga/ds-gsettings3] Audio/Video Cores: Added anoter get_devices method.

[Damien Sandras <dsandras src gnome org>]

commit 3f2e1cd9c4489b78bd0cc45477003cff1ce88600

    Audio/Video Cores: Added anoter get_devices method.
    
    The new method returns a vector of devices represented by their string
    descriptions.
    
    The string description is used by the prefs and in various parts of the
    program. The new method has the big advantage of having the same
    signature whatever the core is unlike the former method which required
    different arguments for each core.
