Remove SSL_version_str

I was never exported in our shared libraries and no one noticed, and
we don't seem to use it ourselves, so clean it away.

In all likelyhood, this is a remain from the 90's, when it was in
fashion to litter library modules with these kinds of strings.

Fix the drbgtest with randomized ordering

In drbgtest, test_set_defaults changes the default DRBGs. This works fine

OPENSSL_TEST_RAND_ORDER is defined then it may fail (dependent on the
ordering). This environment variable is defined for one of the Travis
tests, so this issue was causing intermittent travis test failures.

Refactor linker script generation

The generation of linker scripts was badly balanced, as all sorts of
platform dependent stuff went into the top build.info, when that part
should really be made as simply and generic as possible.

Therefore, we move a lot of the "magic" to the build files templates,
since they are the place for platform dependent things.  What remains
is to parametrize just enough in the build.info file to generate the
linker scripts correctly for each associated library.

"linker script" is a term usually reserved for certain Unix linkers.
However, we only use them to say what symbols should be exported, so
we use the term loosely for all platforms.  The internal extension is
'.ld', and is changed by the build file templates as appropriate for
each target platform.

Note that this adds extra meaning to the value of the shared_target
attribute.

It's actually not a real issue but caused by the absence of the default case
which does not occur in reality but which makes coverity see a code path where
pkey remains unassigned.

SipHash: add separate setter for the hash size

This was originally part of SipHash_Init.  However, there are cases

hash size, and we do allow doing so with a EVP_PKEY control.  The
solution is to provide a separate hash_size setter and to use it in

Do not reset SNI data in SSL_do_handshake()

PR #3783 introduce coded to reset the server side SNI state in
SSL_do_handshake() to ensure any erroneous config time SNI changes are
cleared. Unfortunately SSL_do_handshake() can be called mid-handshake
multiple times so this is the wrong place to do this and can mean that
any SNI data is cleared later on in the handshake too.

Therefore move the code to a more appropriate place.

Simplify SSL_get_servername() to avoid session references

Ideally, SSL_get_servername() would do exactly as it is documented
and return exactly what the client sent (i.e., what we currently
are stashing in the SSL's ext.hostname), without needing to refer
to an SSL_SESSION object.  For historical reasons, including the
parsed SNI value from the ClientHello originally being stored in the
SSL_SESSION's ext.hostname field, we have had references to the
SSL_SESSION in this function.  We cannot fully excise them due to
the interaction between user-supplied callbacks and TLS 1.2 resumption
flows, where we call all callbacks but the client did not supply an
SNI value.  Existing callbacks expect to receive a valid SNI value
in this case, so we must fake one up from the resumed session in
order to avoid breakage.

Otherwise, greatly simplify the implementation and just return the
value in the SSL, as sent by the client.

Restore historical SSL_get_servername() behavior

Commit 1c4aa31d79821dee9be98e915159d52cc30d8403 modified the state machine
to clean up stale ext.hostname values from SSL objects in the case when
SNI was not negotiated for the current handshake.  This is natural from
the TLS perspective, since this information is an extension that the client
offered but we ignored, and since we ignored it we do not need to keep it
around for anything else.

However, as documented in https://github.com/openssl/openssl/issues/7014 ,
there appear to be some deployed code that relies on retrieving such an
ignored SNI value from the client, after the handshake has completed.
Because the 1.1.1 release is on a stable branch and should preserve the
published ABI, restore the historical behavior by retaining the ext.hostname
value sent by the client, in the SSL structure, for subsequent retrieval.
