OpenSSL 3.0 disables a number of "legacy" algorithms by default, and we need to enable them manually using their provider system. Note that explicitly loading a provider will disable the implicit default provider, which is why we need to load it explicitly. Closes #2629 Signed-off-by: Simon Chopin <simon.chopin@canonical.com> V2: * use a local OSSL_LIB_CTX to avoid leaking the legacy algorithms into the main SSL context. * Simplify the fish_init() error paths by calling fish_deinit()
