This is cleaner than the OpenSSL code was, at least, but it's hardly
beautiful due to the "standard" that it's trying to implement. (See
[1].)
The references from the PKCS#8 code to various ciphers have digests have
been made into function pointer references rather than NIDs so that the
linker will be able to drop RC2 code for binaries that don't call PKCS#8
or #12 functions.
A bug that crashed OpenSSL/BoringSSL when parsing a malformed PKCS#8
structure has been fixed too.

Previously, the ASN.1 functions in bytestring were capable of processing
indefinite length elements when the _ber functions were used. That works
well enough for PKCS#3, but NSS goes a bit crazy with BER encoding and
PKCS#12. Rather than complicate the core bytestring functions further,
the BER support is removed from them and moved to a separate function
that converts from BER to DER (if needed).

As useless as it might seem, the certificates in PKCS#12 files appear to
always be encrypted with 40-bit RC2. OpenSSL, NSS and Windows are all
the same on this point. Thus, in order to be able to import PKCS#12
files we need RC2 support.
RC2 has deliberately not been added to EVP_get_cipherbynid so that the
linker can drop the RC2 code unless the PKCS#12 functions are actually
called.

Rather than switching the order of the ServerHello and HelloVerifyRequest

HelloVerifyRequest reading is optional and ServerHello is strict. Use the

Fix the dtls1_stop_timer call in these states to consistently hit the end of a
server flight; the previous flight should not be cleared from the retransmit
buffer until the entire next flight is received. That said, OpenSSL doesn't
appear to implement the part where, on receipt of the previous peer flight, the
buffered flight is retransmitted. (With the exception of a SSL3_MT_FINISHED
special-case in dtls1_read_bytes.) So if the peer is also OpenSSL, this doesn't
do anything.

Of the remaining implementations left, ssl3_, dtls1_, and ssl23_, dtls1_ is
redundant and can be folded into ssl3_. ssl23_ actually isn't; it sets 5
minutes rather than 2 hours. Two hours seems to be what everything else uses
and seems a saner default. Most consumers seem to override it anyway
(SSL_CTX_set_timeout). But it is a behavior change.
The method is called at two points:
- SSL_get_default_timeout
- SSL_CTX_new
Incidentally, the latter call actually makes the former never called internally
and the value it returns a lie. SSL_get_default_timeout returns the default
timeout of the /current/ method, but in ssl_get_new_session, the timeout is
shadowed by session_timeout on the context. That is initialized when
SSL_CTX_new is called. So, unless you go out of your way to
SSL_CTX_set_timeout(0), it always overrides. (And it actually used to a
difference because, for SSL23, the SSL_CTX's method is SSL23, but, when session
creation happens, the SSL's method is the version-specific one.)

ssl23_get_client_hello has lots of remnants of SSLv2 support and remnants of an
even older SSL_OP_NON_EXPORT_FIRST option (see upstream's
d92f0bb6e9ed94ac0c3aa0c939f2565f2ed95935) which complicates the logic.
Split it into three states and move V2ClientHello parsing into its own
function. Port it to CBS and CBB to give bounds checks on the V2ClientHello
parse.
This fixes a minor bug where, if the SSL_accept call in ssl23_get_client_hello
failed, cb would not be NULL'd and SSL_CB_ACCEPT_LOOP would get reported an
extra time.
It also unbreaks the invariant between s->packet, s->packet_length,
s->s3->rbuf.buf, and s->s3->rbuf.offset at the point the switch, although this
was of no consequence because the first ssl3_read_n call passes extend = 0
which resets s->packet and s->packet_length.
It also makes us tolerant to major version bumps in the ClientHello. Add tests
for TLS tolerance of both minor and major version bumps as well as the HTTP
request error codes.
