md5, sha1, sha256, sha512: use openssl routines if available
--with-openssl the libcrypto md5, sha1, sha224, sha256, sha384, sha256
routines will be used if available, requiring apps to link @LIB_CRYPTO@
* lib/gl_openssl.h: Provide wrappers for specified openssl hash.
* m4/gl-openssl.m4 (gl_CRYPTO_CHECK): New function to lookup libcrypto
in the standard system location.
* m4/sha1.m4: Call gl_CRYPTO_CHECK() for SHA1.
* m4/sha256.m4: Likewise with SHA256.
* m4/sha512.m4: Likewise with SHA512.
* m4/md5.m4: Likewise with MD5.
* m4/gc.m4: Ensure @LIB_CRYPTO@ set for tests.
* lib/sha1.h: Include wrappers if HAVE_OPENSSL_SHA1.
* lib/sha256.h: Likewise with SHA256.
* lib/sha512.h: Likewise with SHA512.
* lib/md5.h: Likewise with MD5.
* lib/sha1.c: Exlude functionality if HAVE_OPENSSL_SHA1.
* lib/sha256.c: Likewise with SHA256.
* lib/sha512.c: Likewise with SHA512.
* lib/md5.c: Likewise with MD5.
* modules/crypto/sha1 (Link:): Add the new optional lib.
(Depends-on:): Add dependency on extern-inline.
* modules/crypto/sha256: Likewise.
* modules/crypto/sha512: Likewise.
* modules/crypto/md5: Likewise.
* modules/crypto/sha1-tests: Reference the lib here too.
