init_archive_deb_data()
        We want to filter for data.tar.* in the AR file not the TAR
        file, else we get nothing.

all_control_list()
        Make the 'extensions' array of control file names a global so it
        can be used in unpack_package as well. Name the global
        all_control_files. Don't hard code the length of
        all_control_files but instead used sizeof.

unpack_package()
        Only unpack the control files we are interested in (from
        all_control_files). Extract the data.tar.gz into / rather than
        the current directory.

dpkg_main()
        Configure packages in a second pass so all the packages being
        installed are unpacked before configuring.

Some purely cosmetic changes:

header
        update list of differences since two of them are no longer true.
        The .control file is no longer stored as a result of this patch
        -- it was redundant since the info is in status. New packages
        appear to be added to the end of the status file now rather than
        the start.

remove_package()
        Make message printing optional, so we can avoid a redundant
        message when replacing/upgrading a package. When we do print
        stuff then include the version number.

purge_package()
        Print "Purging xxx (yyy) ..." message like the other actions.

configure_package()
        Add "..." to "Setting up" message to be consistent with other
        actions.

* consider important, its worth keeping a note of differences anyway, just to
* make it easier to maintain.
* - The first value for the Confflile: field isnt placed on a new line.
* - The <package>.control file is extracted and kept in the info dir.
* - When installing a package the Status: field is placed at the end of the
* section, rather than just after the Package: field.
* - Packages with previously unknown status are inserted at the begining of
* the status file
*
* Bugs that need to be fixed
* - (unknown, please let me know when you find any)
