add inventory file creation to create-object-diff

Browse Source 
In preparation for adding an automated test framework,
add an ability to create-object-diff that will create
a human readable list of included sections and symbols
with type and bind information so that the test framework
can compare against a known-good reference list with the
expected set of sections and symbols.

The file is created when the -i/--inventory option is
used.  The inventory filename is the user supplied output
file name suffixed by .inventory
