This allows symlink -sr to dynamically generate the correct relative symlink, given absolute args. e.g. /usr/lib/libm.so -> /lib/libm.so.5 should really be ../../lib/libm.so.5 so that when it is read from outside a jail it still refers to the right place.

svn commit: r309035 - in head/lib/libpathconv: . tests
Author: julian
Date: Wed Nov 23 07:57:52 2016
New Revision: 309035
URL: https://svnweb.freebsd.org/changeset/base/309035
Log:
This little BSD licensed library has been kicking around for years.
It allows one to trivially convert an absolute path to a relative path
and the reverse. The test programs themselves are very useful in scripts
but the real use comes shortly with the -r and -a arguments to ln.
These are sometimes known as the --relative and --absolute flags and
can force a symlink to be relative when you only have an absolue path.
Another place these are sometimes used is to add -a and -r args to 'realpath'.
Incredibly useful in Makefiles.
I was going to just add the files in with 'ln' but a library makes more sense.
The test programs may come out in their own right some day for scripting.

The test directry does not conform to any framework.
