vlib: add plugin override support
Allow a plugin to override (suppress loading of) other plugins. This
mechanism allows a developer to prevent specific plugins from being
loaded.
To do so, provide an "overrides" list in the plugin definition:
VLIB_PLUGIN_REGISTER () =
{
<snip>
.overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so",
};
or some such. Simply list the plugins in question as shown above. The
.overrides structure member is limited to 256 octets. The named .elf
section mechanism used to discover the vlib_plugin_registration_t's
precludes the use of a variable-length array of strings.
Use the vlib log to eliminate plugin and built-in vat plugin loader
console spew.
Added vlib_log_register_class_rate_limit(...) to allow procedural
configuration of the log rate-limit. We *never* want to rate-limit
plugin loader messages.
