boringssl/include/openssl/ssl.h
David Benjamin 9d0847ae6d Add some missing error failure checks. 
Found while diagnosing some crashes and hangs in the malloc tests. This (and
the follow-up) get us further but does not quite let the malloc tests pass
quietly, even without valgrind. DTLS silently ignores some malloc failures
(confusion with silently dropping bad packets) which then translate to hangs.
