[Matthew Barnes <mbarnes src gnome org>]

commit 5c76186ad6770b7e632b1e00f064ef336cb51456
Author: Matthew Barnes <mbarnes redhat com>

    configure.ac: Add --enable-uoa option.
    
    Enables support for Ubuntu's own "Online Accounts" framework (using
    libaccounts-glib and libsignon-glib).
    
    Defines UOA_CFLAGS, UOA_LIBS, and a HAVE_UOA conditional.
