tools: add benchmark for crypto functions.
The benchmark tests the speed of the following algorithms: MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128. It can optionally be built to perform the same benchmark on other crypto libraries, for comparison purposes. The supported libraries are: - crypto: OpenSSL's libcrypto; - gcrypt: GnuTLS's libgcrypt; - tomcrypt: LibTomCrypt To enable them, use this syntax: make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench They do not need to have been enabled in configure.
