Jim Warner 95cd051c27 misc: tweak the recent copyright changes just a little
This commit just tweaks some recent copyright changes.

Foe example, the six public header files are unique to
this new library and thus are just attributed to Craig
and me. Plus, there were some misnamed file references
as '.c' for '.h' or 'libprocps' instead of 'libproc2'.
