crypto: omit stream ops Emacs doesn’t need

* lib/md5.c (md5_stream):
* lib/sha1.c (sha1_stream):
* lib/sha256.c (shaxxx_stream, sha256_stream, sha224_stream):
* lib/sha512.c (shaxxx_stream, sha512_stream, sha384_stream):
Compile stream functions only if GL_COMPILE_CRYPTO_STREAM is
defined.  Emacs needs this, as it does not use the stream
operations and doesn’t need all the af_alg stuff we’ve recently
added.  Perhaps a similar change is needed to the other crypto
modules, but this patch changes only those needed for Emacs.
* modules/crypto/md5-buffer, modules/crypto/sha1-buffer:
* modules/crypto/sha256-buffer, modules/crypto/sha512-buffer:
New modules, used by Emacs.
* modules/crypto/md5, modules/crypto/sha1, modules/crypto/sha256:
* modules/crypto/sha512: Rewrite to depend on the new modules.
