Td4 is an array of u8. A u8 << int promotes the u8 to an int first then shifts.
If the mathematical result of a shift (as modelled by lhs * 2^{rhs}) is not
representable in an integer, behaviour is undefined. In other words, you can't
shift into the sign bit of a signed integer. Fix this by casting to u32
whenever we're shifting left by 24.
(For consistency, cast other shifts, too.)

ASN1_primitive_new takes an ASN1_ITEM * param |it|. There are a couple
of conditional code paths that check whether |it| is NULL or not - but
later |it| is deref'd unconditionally. If |it| was ever really NULL then
this would seg fault. In practice ASN1_primitive_new is marked as an
internal function in the public header file. The only places it is ever
used internally always pass a non NULL parameter for |it|. Therefore, change
the code to sanity check that |it| is not NULL, and remove the conditional
checking.

No code within BoringSSL or Google (grep for EVP_PKEY_CTX_(ctrl|get|set)) is
sensitive to the various failure cases. Normalize it all to 0/1 for simplicity.
This does carry a slight risk: any new ctrl hooks we import from upstream that,
like EVP_PKEY_CTX_get_rsa_oaep_md, return something other than success/failure
cannot be called directly via EVP_PKEY_CTX_ctrl. They instead need to
internally be routed through a struct like CBS and only called through the
wrappers. To that end, unexport EVP_PKEY_CTX_ctrl and require that callers use
the wrappers. No code in Google uses it directly and, if need be, switching to
the wrapper would be an incredibly upstreamable patch.

immediately obvious that the frag_off/frag_len bounds checks and the msg_len

have dtls1_hm_fragment_mark also check internally.

Notably, drop all special cases around receiving a message in order and
receiving a full message. It makes things more complicated and was the source
of bugs (the MixCompleteMessageWithFragments tests added in this CL did not
pass before). Instead, every message goes through an hm_fragment, and
dtls1_get_message always checks buffered_messages to see if the next is
complete.
The downside is that we pay one more copy of the message data in the common
case. This is only during connection setup, so I think it's worth the
simplicity. (If we want to optimize later, we could either tighten
ssl3_get_message's interface to allow the handshake data being in the
hm_fragment's backing store rather than s->init_buf or swap out s->init_buf
with the hm_fragment's backing store when a mesasge completes.
This CL does not address ssl_read_bytes being an inappropriate API for DTLS.
Future work will revise the handshake/transport boundary to align better with
DTLS's needs. Also other problems that I've left as TODOs.

after this check.
This allows us to shave 132 bytes off HMAC_CTX as this was the only reason it
