This change adds the ability to configure ciphers specifically for
TLS ≥ 1.0. This compliments the existing ability to specify ciphers
for TLS ≥ 1.1.
This is useful because TLS 1.0 is the first version not to suffer from
POODLE. (Assuming that it's implemented correctly[1].) Thus one might
wish to reserve RC4 solely for SSLv3.

setup_key_block is called when the first CCS resolves, but for resumptions this
is the incoming CCS (see ssl3_do_change_cipher_spec). Rather than set
need_record_splitting there, it should be set in the write case of
tls1_change_cipher_state.
This fixes a crash from the new record layer code in resumption when
record-splitting is enabled. Tweak the record-splitting tests to cover this
case.
This also fixes a bug where renego from a cipher which does require record
splitting to one which doesn't continues splitting. Since version switches are
not allowed, this can only happen after a renego from CBC to RC4.

This made sense when the cipher might have been standardized as-is, so a

to have some nonce tweaks anyway, there's no sense in keeping this around. Get

Rather than sniff for ClientHello, just fall through to standard logic
once weird cases are resolved.
This means that garbage will now read as WRONG_VERSION rather than
UNKNOWN_PROTOCOL, but the rules here were slightly odd anyway. This also
means we'll now accept empty records before the ClientHello (up to the
empty record limit), and process records of the wrong type with the
usual codepath during the handshake.
This shouldn't be any more risk as it just makes the ClientHello more
consistent with the rest of the protocol. A TLS implementation that
doesn't parse V2ClientHello would do the same unless it still
special-cased the first record. All newly-exposed states are reachable
by fragmenting ClientHello by one byte and then sending the record in
question.

Rather than rely on Chromium to query SSL_initial_handshake_complete in the
callback (which didn't work anyway because the callback is called afterwards),
move the logic into BoringSSL. BoringSSL already enforces that clients never
offer resumptions on renegotiation (it wouldn't work well anyway as client
session cache lookup is external), so it's reasonable to also implement
in-library that sessions established on a renegotiation are not cached.
Add a bunch of tests that new_session_cb is called when expected.
