OpenSSl 3 statically linking a provider

[Kory Hamzeh]

I have written a custom provider which I need to include (link) with my 
Application at link time rather than load it at run-time. The init function is 
defined like this:

OSSL_provider_init_fn sck_provider_init;

int sck_provider_init(const OSSL_CORE_HANDLE *handle,
                       const OSSL_DISPATCH *in,
                       const OSSL_DISPATCH **out,
                       void **provctx)

But I cannot figure out how to initialize/load it in my app. The man page for 
provider(7) states that it is possible to do this, but does not explain how. Is 
that documented somewhere?

Thanks,
Kory
