66c249ce91 Remove some dead code.
This change removes the old ASN.1 functions (ASN1_seq_unpack and
ASN1_seq_pack) which have always been disabled in BoringSSL.

It also removes code enabled by OPENSSL_EXPORT_VAR_AS_FUNCTION, which
we have never used.

6bc658d2e3 Split off private_transform function in RSA.
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.

6f2600199c Mark all SSL_CIPHERs as const.
This lets us put the SSL_CIPHER table in the data section. For type-checking,
make STACK_OF(SSL_CIPHER) cast everything to const SSL_CIPHER*.

Note that this will require some changes in consumers which weren't using a

98e882ead1 Clean up s23_srvr.c.
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.

With this change, we don't have any compiler scarecrows for
OPENSSL_cleanse any longer when using OPENSSL_NO_ASM :( Maybe, one day,
we'll get memset_s in our base platform.

eb7d2ed1fe Add visibility rules.
This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.

On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h

In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.

In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

ad1907fe73 Use asm directives to protect OPENSSL_cleanse.
Compilers have a bad habit of removing "superfluous" memset calls that
are trying to zero memory. For example, when memset()ing a buffer and
then free()ing it, the compiler might decide that the memset is
unobservable and thus can be removed.

Previously we tried to stop this by a) implementing memset in assembly
on x86 and b) putting the function in its own file for other platforms.

This change removes those tricks in favour of using asm directives to
scare the compiler away. As best as our compiler folks can tell, this is
sufficient and will continue to be so.

Where possible, functions should return one for success and zero for
error. The use of additional negative values to indicate an error is,
itself, error prone.

This change fixes many EVP functions to remove the possibility of
negative return values. Existing code that is testing for <= 0 will
continue to function, although there is the possibility that some code
was differentiating between negative values (error) and zero (invalid
signature) for the verify functions and will now show the wrong error
message.
