api: autogenerate api trace print/endian

In addition to the external vppapitrace tool, VPP itself supports dumping of API trace files.
In two formats, "custom-dump" and "dump". "dump" gives a human friendly list,
and "custom-dump" is meant to give a list of commands that can be fed to VAT.
This patch only deals with "dump".
Prior to this fix, auto-generation was only done for the basic types.
This fix adds support for any type, including lists, and supports pretty-printing
of enums, strings, IP addresses, MAC addresses and so on.

Usage: api trace dump <api-trace-file>

For example
