Windows x64 uses the IL32P64 data model, which means that unsigned int
is 32 bits and size_t is 64 bits. Previously, the expression
|~(alignment - 1)| resulted in the 32-bit value 0xFFFFFFF0, which was
then extended to the 64-bit value 0x00000000FFFFFFF0 when promoted to
size_t. When the input pointer was masked with this value, the result
was a pointer that was usually way outside the boundaries of the array.
The new code casts |alignment| to size_t first prior to the bitwise
negation, resulting in the correct mask value of 0xFFFFFFFFFFFFFFF0.

This mostly[*] doesn't matter for TLS since the message would have been
rejected anyway, but, in DTLS, if the peer rejects our Finished, it will send
an encrypted alert. This will then cause it to hang, which isn't very helpful.
I've made the change on both TLS and DTLS so the two protocols don't diverge on
this point. It is true that we're accepting nominally encrypted and
authenticated alerts before Finished, but, prior to ChangeCipherSpec, the
alerts are sent in the clear anyway so an attacker could already inject alerts.
A consumer could only be sensitive to it being post-CCS if it was watching
msg_callback. The only non-debug consumer of msg_callback I've found anywhere
is some hostapd code to detect Heartbeat.
See https://code.google.com/p/webrtc/issues/detail?id=4403 for an instance
where the equivalent behavior in OpenSSL masks an alert.
[*] This does change behavior slightly if the peer sends a warning alert
between CCS and Finished. I believe this is benign as warning alerts are
usually ignored apart from info_callback and msg_callback. The one exception is
a close_notify which is a slightly new state (accepting close_notify during a
handshake seems questionable...), but they're processed pre-CCS too.

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.

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.
