We were calling g_module_symbol() 2703 times, which is actually more
expensive than you'd think.
It also means the plugins are actually what we tell people they are:
A set of vfuncs that get run. The reality before that they were dlsym'd
functions that get called at pretty random times.
More than one person has asked about 'why call fu_plugin_update() for a
reinstall or downgrade' and I didn't have a very good answer.
The plugin API is not officially stable, and we should fix things to be
less confusing. Use the same verbs as the FuDevice vfuncs instead.
