Prefer pciids database from ports if present

Given the pciids database on ports is updated more often than the one in base
prefer this version if present, otherwise read the one from base.

Update to improve handling of verbose PCI vendor/device information.

- Read the database from /usr/share/misc (or wherever else we're pointed)
rather than compiling it in.
- Decode the class/subclass fields if requested.
- Print things in a slightly longer but more readable format.

This commit was generated by cvs2svn to compensate for changes in r19102,
which included commits to RCS files with non-trunk default branches.

Initial version of the user land code for the PCI config register
access functions. Written by Garrett Wollman and modified by me to
better match my view of the (PCI) world.
