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. Type: refactor Change-Id: Iac908e5af7d5497c78d6aa9c3c51cdae08374045 Signed-off-by: Dave Barach <dave@barachs.net>
