pmap: New switches - RC support (-n/-N,-c/C) & ShowPath (-p)
This commit introduces 4 new switches for the RC support and 1 more switch for toggling the path printing in the mapping field. the configuration file can be used for a selection of columns to be displayed and for toggling the path printing in the mapping field.
