int ossl_provider_activate(OSSL_PROVIDER *prov, int retain_fallbacks,
int upcalls);
CORE: Separate OSSL_PROVIDER activation from OSSL_PROVIDER reference This introduces a separate activation counter, and the function ossl_provider_deactivate() for provider deactivation. Something to be noted is that if the reference count goes down to zero, we don't care if the activation count is non-zero (i.e. someone forgot to call ossl_provider_deactivate()). Since there are no more references to the provider, it doesn't matter. The important thing is that deactivation doesn't remove the provider as long as there are references to it, for example because there are live methods associated with that provider, but still makes the provider unavailable to create new methods from.

/* Check if the provider is available (activated) */
Add functions to see if a provider is available for use. Public function OSSL_PROVIDER_available() takes a library context and a provider name, and returns 1 if it's available for use, i.e. if it's possible to fetch implementations from it, otherwise 0. Internal function ossl_provider_activated() returns 1 if the given OSSL_PROVIDER is activated, otherwise 0. To make this possible, the activation of fallbacks got refactored out to a separate function, which ended up simplifying the code.

Replumbing: give the possibility for the provider to create a context OSSL_provider_init() gets another output parameter, holding a pointer to a provider side context. It's entirely up to the provider to define the context and what it's being used for. This pointer is passed back to other provider functions, typically the provider global get_params and set_params functions, and also the diverse algorithm context creators, and of course, the teardown function. With this, a provider can be instantiated more than once, or be re-loaded as the case may be, while maintaining instance state.

Add 'on demand self test' and status test to providers The default and legacy providers currently return 1 for status and self test checks. Added test to show the 3 different stages the self test can be run (for installation, loading and on demand). For the fips provider: - If the on demand self test fails, then any subsequent fetches should also fail. To implement this the cached algorithms are flushed on failure. - getting the self test callback in the fips provider is a bit complicated since the callback hangs off the core libctx (as it is set by the application) not the actual fips library context. Also the callback can be set at any time not just during the OSSL_provider_init() so it is calculated each time before doing any self test.
