Rather than switching the order of the ServerHello and HelloVerifyRequest
states and processing each twice, have the states follow the protocol order.
HelloVerifyRequest reading is optional and ServerHello is strict. Use the
send_cookie bit to determine whether we're expecting a cookie or not.
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.
Also fix the DTLS test which wasn't actually asserting that the ClientHello
matched.

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.

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.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.
This doesn't work on Windows.
This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.

opensslv.h to continue to compile.

Now that the consuming code in ssl/ is removed, there is no need for this.
Leave SSL_COMP and STACK_OF(SSL_COMP) for now so as not to break any code which
manipulates the output of SSL_COMP_get_compression_methods to disable
compression.
