getdirs.awk: - improve parsing; explicitly skip lines we don't want and use the rest. - keep track of which items were explicitly listed, and only output directories at the END which weren't listed, each with a suffix of "optional". - convert to my awk KNF join.awk: - when joining, output all of the matching entry from the first file and the 2nd & subsequent lines of the entry from the second file. - convert to my awk KNF these changes mean that maketars use of pax will result in tar files with the traditional behaviour of only containing the necessary directories, rather than all the parent directories required to get to a particular item. this latter behaviour was necessary for METALOG (i.e UNPRIVED) pax .tgz set file generation, until the changes above fixed it.

# $NetBSD: join.awk,v 1.2 2002/05/19 13:32:44 lukem Exp $
- clean up SDIR (temporary directory) creation - improve munging of NetBSD.dist and METALOG into metalog, using mtree to "cleanup" / "merge" entries, and don't sort the result. relies upon mtree to not change the order (see below) - use (newly added) join.awk to output lines in metalog that are listed in flist.${set}. join.awk doesn't require either file to be sorted (unlike join(1)), which is required because we want to retain the order of the metalog, because certain entries in the metalog (such as hard links) make assumptions about the permissions of earlier entries. this should fix [toolchain/16207]
