Dave Barach 21a438465c vat: unload unused vat plugins 
If the corresponding vpp plugin is absent, return a non-zero
clib_error_t * from vat_plugin_register ("xxx plugin not loaded"). The
vat plugin calls dlclose on the vat plugin, and it disappears.

Depending on the plugin configuration, this can reduce the vpp virtual
size by several gigabytes.

Added a VAT_PLUGIN(<plugin-name>) macro to vat_helper_macros, clean up
boilerplate vat_plugin_register() implementations. Fixed a number of
non-standard vat_plugin_register methods.

Dave Barach 7c91007e1e Make the loss / delay sim available as an output feature 
Add binary api and debug cli support.

Rewrite for speed: enqueue vlib_buffer_t's to the wheel, instead of
memcpy'ing data. Quad-loop the output feature / x-connect (interior)
node. Prefetch wheel entries in the input node.

Save packet-generator-based unit-test setup in extras/nsim.

Simple config example:

set nsim delay 20 ms bandwidth 1 gbit packet-size 1024
nsim output-feature enable-disable GigabitEthernet3/0/0
