YOCTO #1088: documentation - Added text to partially address package bug

This bug was filed by Gary Thomas and was requesting more information
on the "hows" and "whys" of setting up your own package repositories.
At this point, I have added information to help the user understand
build performance issues when choosing between the RPM and IPKG packaging
systems.  Likely, there is more that needs to be added to fully address
this bug.

For now, I added explanations in the packaging class and glossary areas
of the YP reference manual, a new paragraph in the YP QS just prior to
firing off a build, and a new bit of information in the configuring
PMS in the ADT Manual.
