The value of BIO_CTRL_DGRAM_SET_PEEK_MODE was clashing with the value for
BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE. In an SCTP enabled build
BIO_CTRL_DGRAM_SCTP_SET_IN_HANDSHAKE was used unconditionally with
the reasoning that it would be ignored if SCTP wasn't in use. Unfortunately
due to this clash, this wasn't the case. The BIO ended up going into peek
mode and was continually reading the same data over and over - throwing it
away as a replay.

Issue 1:
sh.bittable_size is a size_t but i is and int, which can result in
freelist == -1 if sh.bittable_size exceeds an int.
This seems to result in an OPENSSL_assert due to invalid allocation
size, so maybe that is "ok."
Worse, if sh.bittable_size is exactly 1<<31, then this becomes an
infinite loop (because 1<<31 is a negative int, so it can be shifted
right forever and sticks at -1).
Issue 2:
CRYPTO_secure_malloc_init() sets secure_mem_initialized=1 even when
sh_init() returns 0.
If sh_init() fails, we end up with secure_mem_initialized=1 but
sh.minsize=0. If you then call secure_malloc(), which then calls,
sh_malloc(), this then enters an infite loop since 0 << anything will
never be larger than size.
Issue 3:
That same sh_malloc loop will loop forever for a size greater
than size_t/2 because i will proceed (assuming sh.minsize=16):
i=16, 32, 64, ..., size_t/8, size_t/4, size_t/2, 0, 0, 0, 0, ....

In SCTP the code was only allowing a send of a close_notify alert if the
socket is dry. If the socket isn't dry then it was attempting to save away
the close_notify alert to resend later when it is dry and then it returned
success. However because the application then thinks that the close_notify
alert has been successfully sent it never re-enters the DTLS code to
actually resend the alert. A much simpler solution is to just fail with a
retryable error in the event that the socket isn't dry. That way the
