This is the equivalent of FragmentAcrossChangeCipherSuite for DTLS. It
is possible for us to, while receiving pre-CCS handshake messages, to
buffer up a message with sequence number meant for a post-CCS Finished.
When we then get to the new epoch and attempt to read the Finished, we
will process the buffered Finished although it was sent with the wrong
encryption.
Move ssl_set_{read,write}_state to SSL_PROTOCOL_METHOD hooks as this is
a property of the transport. Notably, read_state may fail. In DTLS
check the handshake buffer size. We could place this check in
read_change_cipher_spec, but TLS 1.3 has no ChangeCipherSpec message, so
we will need to implement this at the cipher change point anyway. (For
now, there is only an assert on the TLS side. This will be replaced with
a proper check in TLS 1.3.)

downstreams only need to manage a small change atomically. We'll remove

This isn't filled in on the client and Chromium no longer uses it for
plain RSA. It's redundant with existing APIs. This is part of removing
the need for callers to call SSL_get_session where possible.
SSL_get_session is ambiguous when it comes to renego. Some code wants
the current connection state which should not include the pending
handshake and some code wants the handshake scratch space which should.
Renego doesn't exist in TLS 1.3, but TLS 1.3 makes NewSessionTicket a
post-handshake message, so SSL_get_session is somewhat silly of an API
there too.
SSL_SESSION_get_key_exchange_info is a BoringSSL-only API, so we can
freely change it and replace it with APIs keyed on SSL. In doing so, I
think it is better to provide APIs like "SSL_get_dhe_group_size" and
"SSL_get_curve_id" rather than make the caller do the multi-step
SSL_get_current_cipher / SSL_CIPHER_is_ECDHE dance. To that end, RSA

OpenSSL's SSL_OP_NO_* flags allow discontinuous version ranges. This is a
nuisance for two reasons. First it makes it unnecessarily difficult to answer
"are any versions below TLS 1.3 enabled?". Second the protocol does not allow
discontinuous version ranges on the client anyway. OpenSSL instead picks the
first continous range of enabled versions on the client, but not the server.
This is bizarrely inconsistent. It also doesn't quite do this as the
ClientHello sending logic does this, but not the ServerHello processing logic.
So we actually break some invariants slightly. The logic is also cumbersome in
DTLS which kindly inverts the comparison logic.
First, switch min_version/max_version's storage to normalized versions. Next
replace all the ad-hoc version-related functions with a single
ssl_get_version_range function. Client and server now consistently pick a
contiguous range of versions. Note this is a slight behavior change for
servers. Version-range-sensitive logic is rewritten to use this new function.

Now that retransitting is a lot less stateful, a lot of surrounding code can
lose statefulness too. Rather than this overcomplicated pqueue structure,
hardcode that a handshake flight is capped at 7 messages (actually, DTLS can
only get up to 6 because we don't support NPN or Channel ID in DTLS) and used a
fixed size array.

Now dtls1_do_handshake_write takes in a serialized form of the full message and
writes it. It's a little weird to serialize and deserialize the header a bunch,
but msg_callback requires that we keep the full one around in memory anyway.
Between that and the handshake hash definition, DTLS really wants messages to
mean the assembled header, redundancies and all, so we'll just put together
messages that way.
This also fixes a bug where ssl_do_msg_callback would get passed in garbage
where the header was supposed to be. The buffered messages get sampled before
writing the fragment rather than after.

cases which we're stuck with for compatibility will live in SSL_set_bio. It
will internally BIO_up_ref if necessary and appropriately no-op the left or

OpenSSL's bbio logic is kind of crazy. It would be good to eventually do the
buffering in a better way (notably, bbio is fragile, if not outright broken,
for DTLS). In the meantime, this fixes a number of bugs where the existence of
bbio was leaked in the public API and broke things.
- SSL_get_wbio returned the bbio during the handshake. It must always return
the BIO the consumer configured. In doing so, internal accesses of
SSL_get_wbio should be switched to ssl->wbio since those want to see bbio.
For consistency, do the same with rbio.
- The logic in SSL_set_rfd, etc. (which I doubt is quite right since
SSL_set_bio's lifetime is unclear) would get confused once wbio got wrapped.
Those want to compare to SSL_get_wbio.
- If SSL_set_bio was called mid-handshake, bbio would get disconnected and lose
state. It forgets to reattach the bbio afterwards. Unfortunately, Conscrypt
does this a lot. It just never ended up calling it at a point where the bbio
would cause problems.
- Make more explicit the invariant that any bbio's which exist are always
attached. Simplify a few things as part of that.

Those checks contradict an assert up in read_app_data. This is part of
shrinking read_bytes further into get_record and its callers until it goes
away. Here, this kind of policy should be controlled by the callers.

This was needed because ssl3_get_message would get confused if init_num were
not set back to zero when reading the next message. However, ssl3_get_message
now treats init_num only as an output, not an input. (The message sending logic
and the individual handshake states still use it, so we can't get rid of it
altogether yet.)
I've kept the init_num reset at the start and end of the handshake loop alone
for now since that's more about initialization and cleanup. Though I believe
they too do not do anything.

They're completely unused now. The handshake message reassembly logic should
not depend on the state machine. This should partially free it up (ugly as it
is) to be shared with a future TLS 1.3 implementation while, in parallel, it
and the layers below, get reworked. This also cuts down on the number of states
significantly.
Partially because I expect we'd want to get ssl_hash_message_t out of there
too. Having it in common code is fine, but it needs to be in the (supposed to
be) protocol-agnostic handshake state machine, not the protocol-specific
handshake message layer.

Rather than this confusing coordination with the handshake state machine and
init_num changing meaning partway through, use the length field already in
BUF_MEM. Like the new record layer parsing, is no need to keep track of whether
we are reading the header or the body. Simply keep extending the handshake
message until it's far enough along.
ssl3_get_message still needs tons of work, but this allows us to disentangle it
from the handshake state.
