Update strength_bits for 3DES.

Fix strength_bits to 112 for 3DES.
SRP ciphersuite correction.

SRP ciphersuites do not have no authentication. They have authentication
based on SRP. Add new SRP authentication flag and cipher string.
Fix null pointer errors.

PR#3394
Create test/testutil.h for unit test helper macros

Defines SETUP_TEST_FIXTURE and EXECUTE_TEST, and updates ssl/heartbeat_test.c
using these macros. SETUP_TEST_FIXTURE makes use of the new TEST_CASE_NAME
macro, defined to use __func__ or __FUNCTION__ on platforms that support those
symbols, or to use the file name and line number otherwise. This should fix
several reported build problems related to lack of C99 support.
add ECC strings to ciphers(1), point out difference between DH and ECDH

 * Make a clear distinction between DH and ECDH key exchange.
 * Group all key exchange cipher suite identifiers, first DH then ECDH
 * add descriptions for all supported *DH* identifiers
 * add ECDSA authentication descriptions
 * add example showing how to disable all suites that offer no
   authentication or encryption

Apparently clang 3.1, which ships with FreeBSD 9.1, completely ignores
-fsanitize. Clang 3.3, which ships with FreeBSD 9.2, compiles with it, but
fails to link due to the absence of libasan:
