bintrans: move files to a new directory

And reflect the change in various places.

Modularize uuencode and uudecode by wrapping them in bintrans.c

The program will be installed as bintrans, uuencode, uudecode,
b64encode, and b64decode and will be responsible for running the coders
according to their historical behavior.

Additionally, bintrans will be able to take a parameter designating
the coder and accept all its options in this form:
bintrans <coder> [options]
and the behavior should be the same as if
<coder> [options]
was invoked.
This has the advantage that adding coders won't require installing them
as binaries.

Move uudecode files to uuencode since the latter is the one that
provides the manual page.

Disconnect libpathconv tests since they require external perl and do not work with kyua.

This reverts r325192 and is due to libpathconv being connected in r325186.

pfctl parser tests

Copy the most important test cases from OpenBSD's corresponding
src/regress/sbin/pfctl, those that run pfctl on a test input file and check
correctness of its output. We have also added some new tests using the same
format.

The tests consist of a collection of input files (pf*.in) and
corresponding output files (pf*.ok). We run pfctl -nv on the input
files and check that the output matches the output files. If any
discrepancy is discovered during future development in the source
tree, we know that a regression bug has been introduced into the tree.
