Update pilot-link-libs, pilot-link, p5-pilot-link to 0.12.1

pilot-link v0.12.1
There isn't much "new" in this release, just some rapid-fire bug fixes
reported from users and a lot of code has been cleaned up in the tree
to remove unnecessary includes.
* Code cleanup in libpisock, libpisync, src and include
* Fixed the installation faux pas with udev rules, oops!

pilot-link v0.12.0
pilot-link 0.12.0 "Trois ans" ("Three Years") is now official.
There have been so many changes in this release and I can't remember
them all, but here's the short list:
* Many of the userland binaries now have new names, to avoid some
  potential namespace collisions (dlpsh is now pilot-dlpsh for example,
  memos is now pilot-memos). If you use scripts which call these
  applications, you may have to make minor changes to accomodate the
  new naming scheme.
* Documentation is now in DocBook XML, and manpages are dynamically
  generated from that source. Other docs are much more detailed, and
  there are quite a few README files that have been added to help.
* Direct libusb support! This is one of the most monumental features in
  0.12.0, and should help those who have trouble using the kernel's
  visor driver in Linux with their device. Now you can get a healthy
  300% to 600% speedup in sync times, depending on your Palm's
  processor speed. See doc/README.libusb for details. Thanks go to
  Zephania Hull for working out how to get native libusb working with
  pilot-link.
* Native support for Mac OS X. You can now just download the tarball
  and build it directly on Mac OS X machines, and it will just run.
  Thanks go to Florent Pillet for his tireless work in getting this all
  working efficiently and for squashing countless bugs in the libraries
  along the way.
* So many other fixes, additions, features and new things to count.
