Subject: 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
