The upcoming support for the RFC 7919 ffdhe group parameters will be made available in the form of templates like "ffdhe2048(dh)", "ffdhe3072(dh)" and so on. Template instantiations thereof would wrap the inner "dh" kpp_alg and also provide kpp_alg services to the outside again. The primitves needed for providing kpp_alg services from template instances have been introduced with the previous patch. Continue this work now and implement everything needed for enabling template instances to make use of inner KPP algorithms like "dh". More specifically, define a struct crypto_kpp_spawn in close analogy to crypto_skcipher_spawn, crypto_shash_spawn and alike. Implement a crypto_grab_kpp() and crypto_drop_kpp() pair for binding such a spawn to some inner kpp_alg and for releasing it respectively. Template implementations can instantiate transforms from the underlying kpp_alg by means of the new crypto_spawn_kpp(). Finally, provide the crypto_spawn_kpp_alg() helper for accessing a spawn's underlying kpp_alg during template instantiation. Annotate everything with proper kernel-doc comments, even though include/crypto/internal/kpp.h is not considered for the generated docs.
