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

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 ?

which is now included.
