Create very basic "generic" stat tap API to create a "GUI" independent table.

A few sample tap/dissectors (ANSI/A, ANSI MAP) are also included to test the API.  The "GUI output" is a bit raw and could use some "prettying up", but all the basic hooks are there.

Telephony "stat grouping" needs to be better alphabetized to properly populate menu (on GTK, probably Qt)
