15c3512614 Sometimes i get carried away with the use of function pointers, im sure
it seemed like a good idea at the time.

c9f1fce9bb A strict interpretation of the ustar format requires the type flag to be
interpreted, we cannot depend on the file type being set in the mode
field.

fea4b446df Important bugfixes from Ian Campbell.
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.

7ffe133864 As we no longer use function pointers for read in common archiving code
archive_xread can be replaced with bb_full_read, and archive_copy_file
with bb_copyfd*
bb_copyfd is split into two functions bb_copyfd_size and bb_copyfd_eof,
they share a common backend.

5699b8525e Move from read_gz to the pipe()+fork() method.
open_transformer(), common code for pipe+fork.
Function pointer for read() no longer needed.
Allow inflate to be initialised with a specified buffer size to avoid
over-reading.
Reset static variables in inflate_get_next_window to fix a bug where
only the first file in a .zip would be be extracted.

Hi Glenn.

I analysed BSS size gzip applet and found may be mistake:
updcrc() checking  if (crc_table_empty) but not resetted this var.
This do make slow gzip applet ;-)

28d4e16cd7 This appears to be the correct fix to make CONFIG_FEATURE_DEB_TAR_BZ2
support compile.  Glenn, you may want to verify this.

2685724e23 Fix tar -j support
Use the old fork() method of tar compression support, rather than
read_bz2....
 - (*uncompress)(int in, int out) seems like a more natural interface
for compression code.
 - it might improve performance by seperating the work into one cpu
bound and one io bound process.
 - There is extra code required to do read_[gz|bunzip] since (*uncompress)(int in,
int out) will normally be used by the standalone compression applet.

There have been problems with this method so if you see a "Short read"
error let me know.
