Old script was slow and didn't preserve hardlinks within the source set.
This script doesn't link files that are identical within the source set,
ie same checksum & attributes, but different inode. It can only link
such files to similar files from older builds. This deficiency will be
addressed in a separate commit.
TESTS
===================
* Manually test various input directories, including:
- a directory that contains each type of file (regular, devices,
sockets, symlinks, etc)
- old index files with spaces in file names
* Given a build with a dozen or so historical builds,
copied the "aptly" directory and compared timing and destination
directory size before/after this patch:
- old script: time=4m13s size=56.0G
- new script: time=14s size=6.1G
* Run a Jenkins build that rebuilds one package, and doesn't
clean/rebuild the ISO. Make sure "archive-misc" works as expected.
