      + merge in packages, not contained in any patch

    Cleanup: kill unpleasant g_strv_length calls.
    Re-work install_packages_thread
    	+ detect available packages that are already installed, and
    	  forbid re-installation (the PackageKit way)
    	+ emit all-packages-already-installed error
    	+ search for PoolItems using the better search-by-name iterator
    First cut at specifying packages that cannot be removed and suitably
    aborting a transaction if they are requested to be so

    Fix problem whereby the terminal wouldn't return data to scanf from
    a read before newline; but pk_console_get_number would only consume
    the digits, leaving a '\n' malingering to break a subsequent
    pk_console_getchar_unbuffered.
