Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.
Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.

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).

RC2 has deliberately not been added to EVP_get_cipherbynid so that the

This change extracts two, common parts of RSA_decrypt and RSA_sign into
a function called |private_transform|. It also allows this to be
overridden in a method, which is convenient for opaque keys that only
expose the raw RSA transform as it means that the padding code from
BoringSSL can be easily reimplemented.
One significant change here is that short RSA ciphertexts will no longer
be accepted. I think this is correct and OpenSSL has a comment about PGP
mistakenly stripping leading zeros. However, these is the possibility
that it could break something.

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.
