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.
