Move canonicalize() into a separate file, and add some
testing code that can be enabled by compiling with
-DTEST_PROGRAM. There are some built-in test paths,
as well as the ability to read tests from a file.

Rework the Makefile a bit, so .o files get
built individually and have proper dependencies,
and other reorganization.

There are two places in swabber where it is building
up a list of filenames, by constructing a linked list.
These lists gets searched for a match before adding
a new filename, so that filenames are only added once.
Scanning down this unordered linked list can be very
expensive as the list grows. Many of the files can
be referenced many times, and we can speed up the
detecting of matches by moving a matched entry to
the front of the list. This way frequently found
filenames tend to stay towards the beginning of the
list, making checks for them much quicker.

Most of the files in the package_files list are
not referenced, and hence they don't get any tags.
Yet the print_tags routine was walking down the
entire package_files list for every package.
This simple optimization is to create a linked
list of just those package_files records that
contain tags, and then iterate over that shorter
list for each package.
In my test case it went from walking an array
of over 170,000 items, to walking a linked list
of only 100 item.

This change improves the RPM processing of update_distro.
It takes advantage of a new helper program, swab_testf,
to do all the file verification and creation of the *.list
files. Generating the list of input for swab_testf can
be done with a single rpm query, the output of which can
then be sorted and piped through a sed command to create
the input for swab_testf.

This is a major performance improvement for the update_distro
program. The old code maintained an alpabetically
sorted list of file names, and eliminating duplicates as
it went. But every insertion required walking back and
forth down the linked list, making it very inefficient as
the list grew in length.
The new code just creates a simple linked list of all the
file names. It then puts that list into an array, and uses
qsort() to alpabatize them, and mark the duplicate names
during the sorting process. It can then recreate the simple
linked list in alphabetic order, dropping the duplicates
as it goes.

Add the swab_testf program. This is a helper program for
use by "update_distro". It takes a list of files, separated
by "# pkg.list", and dumps into each pkg.list file the
files listed after it that exist and are either a regular
file or a symbolic link, omitting everything else. This is
more efficient that doing the same testing in a shell script.

Convert the argument processing to use getopt(3).
Also convert the parsing of the -c option to be
in a separate subroutine, and to make use of the
strtok(3) routine, and add the ability to prepend
the task names with '-' to disable that task.
