wolfssl/tests/api/test_ocsp.c
Sean Parkinson c111c5bacc Regression testing 
x509.c: realloc may fail and therefore need to store result in a
temporary so the old pointer is not lost.

tls.c: free the name if it is not pushed on to the stack of peer CA
names. Failure to push can be from memory allocation failure.

aes.c: Don't compile XTS decrypt functions without HAVE_AES_DECRYPT.

Fix tests to have better pre-processor protection.
