make pkgutil.{cpp,h} as external library?

[sighook]

Is it a good idea to make pkgutil.{cpp,h} as external library? Something like libpkgutil.{so,a}. Should we keep these files in the pkgutils project?

There are not so many lines of code:

$ wc -l pkgutil.*
 1109 pkgutil.cpp
  120 pkgutil.h
 1229 total

We can provide dynamic and static linking support and make an availability not only to pkg{add,info,rm} to link against it, but to pkgman too.
