c2bf5cad79 General cleanup of comments, defines, includes, and global variables, removed those that arent needed, grouped those remaining at the top.
Re-ordered functions to the order they are called.
Removed static crc table, it now generates the table once for itself.
Results in source reduced by 40%, so it should be a lot easier to work on in the future, binary size only reduced by under 2KB though.

46a98dfb13 Reverted my conversion of tar to getopt to ensure tar can
handle traditional semantics (i.e. 'tar -xvf -' or 'tar xvf'
now both work).

fd3741d712 Remove definition of basename.
It was defined out so that it would never be seen, and if it was ever seen it wasnt used for anything. It also stops gunzip compiling under the Hurd.

segfaulting or handling errors the same way themselves.

fca8050f0f Fix .deb unpack and experimental TAR support
The previous ar.c fialed to recognise one record in .debs

Experimental tar support, this is currently *very* cheap because ar and
tar are functionally similar. It  will need lots of testing so by
default tar support code is defined out.
To test uncomment the line "#define BB_AR_EXPERIMENTAL_UNTAR"

e2b345a6d8 Implemented new ar functionality unique to busybox ar (i think), the -R
option enable a Recursive extraction (or listing) to take place.

i.e. if any files being extracted are themselves ar archives then
busybox ar will extract their contents as well.

e.g. take bar.deb and do (with GNU ar) ar -q foo.deb b.ar
then with busybox ar can do ar -x b.ar data.tar.gz

-R isnt used for anything in GNU ar so i think it should be ok, could
have used long options

This functionality will become (more) usufull with tar, gz support.

437bf72785 Changed getopt so that options can be grouped together, the source
archive is now assumed to be the first non parameter.

This is how GNU ar behaves.

8324b9f1aa Now supports GNU style long filenames.
If no filenames are specifed to be (extracted/listed) it will act on
all files in the archive (i dont think the old version did this)

Code is structured to better support upcoming recursive extraction
functionality.

The old code was a bit strange in places, dont know what i was thinking.

06aeb6c417 ar.c now uses a linked list to process headers, uses getopt, new internal function extractAr(srcFD, dstFd, filename) to make it easily accessable to other busybox functions.
moved copySubFile from ar.c to utilities.c

modified dd.c to use fullWrite

modified copyFile in utilities.c to use copySubFile

fdd5103348 Merge in two patches from Dave Cinege:
the first is a cleanup of tar --exclude
    the second changes mount so mtab works more as it should, and
    also allows mount to use the traditional short form (i.e.
    'mount / -o remount,rw' now works.

While inside tar, I changed it to use getopt...

3adffb7fc8 readlink(2) does not NULL terminate the buffer it reads in, but tar expected it
to do so.  This caused symlinks stored in tarballs to likely have trailing
crap in the stored symlink named.  Oops.

852ff13fc4 Update to ar.c from Glenn McGrath. His comments follow:
------------------------------

the attached diff applies to the ar.c i originally submitted

Changes

Preserve dates now works.
Extracted files are set to the uid, gid and mode specified in the
archive.
Checks for valid end of header marker.
Correctly unpacks newer debian files. (has a '\n' character between
entries)
Added more comments.
Cleaned up code.
Added a last modified date to help keep track of versions.


TODO

Common functionality in ar.c are in tar.c should be merged, in
particular getOctal and extractSubFile.

Should all functions that are used by multiple file go in utilities.c ?
