Add documentation for %b -- provided shared libraries, and clarify
that %B is for required shared libraries.
pkg query and pkg rquery -- pkg_printf()-ify first step.
Add new %N pkg_printf() escape: Repository name, plus doccumentation
and testing for the same.
Use the new %N pkg_printf() format.
Actually, change %N to produce the repo identity -- the tag that is
used in pkg.conf(5) -- rather than repo name: the basename of the
sqlite file and the name the database is mounted as (which is properly
of interest only to the inernals of pkg, and not what we want pkg query
etc. to display).
Use pkg_printf() %N format to print repo identities
