Don't call strncpy with strlen of the source as the length. Don't call
strlen multiple times. Eventually we will want to replace this with a proper
PACKET style handling (but for construction of PACKETs instead of just
reading them as it is now). For now though this is safe because
PSK_MAX_IDENTITY_LEN will always fit into the destination buffer.
This addresses an OCAP Audit issue.

In preparation for splitting this function up into smaller functions this
commit reduces the scope of some of the variables to only be in scope for
the algorithm specific parts. In some cases that makes the error handling
more verbose than it needs to be - but we'll clean that up in a later
commit.

PROGRAM_NO_INST, ENGINES_NO_INST, SCRIPTS_NO_INST and LIBS_NO_INST are
to be used to specify program, engines, scripts and libraries that are
not to be installed in the system. Fuzzers, test programs, that sort
of things are of the _NO_INST type, for example.
For the benefit of build file templates and other templates that use
data from configdata.pm, a new hash table $unified_info{install} is
created. It contains a set of subhashes, one for each type of
installable, each having an array of file names as values. For
example, it can look like this:
"install" =>
{
"engines" =>
[
"engines/afalg/afalg",
"engines/capi",
"engines/dasync",
"engines/padlock",
],
"libraries" =>
[
"libcrypto",
"libssl",
],
"programs" =>
[
"apps/openssl",
],
"scripts" =>
[
"apps/CA.pl",
"apps/tsget",
"tools/c_rehash",

The static function key_exchange_expected() used to return -1 on error.
Commit 361a119127 changed that so that it can never fail. This means that
some tidy up can be done to simplify error handling in callers of that
function.

Having received a ClientKeyExchange message instead of a Certificate we
know that we are not going to receive a CertificateVerify message. This
means we can free up the handshake_buffer. However we better call
ssl3_digest_cached_records() instead of just freeing it up, otherwise we
later try and use it anyway and a core dump results. This could happen,
for example, in SSLv3 where we send a CertificateRequest but the client
sends no Certificate message at all. This is valid in SSLv3 (in TLS
clients are required to send an empty Certificate message).
Found using the BoringSSL test suite.

In TLS if the server sends a CertificateRequest and the client does not
provide one, if the server cannot continue it should send a
HandshakeFailure alert. In SSLv3 the same should happen, but instead we
were sending an UnexpectedMessage alert. This is incorrect - the message
isn't unexpected - it is valid for the client not to send one - its just
that we cannot continue without one.

In TLS during ClientAuth if the CA is not recognised you should get an
UnknownCA alert. In SSLv3 this does not exist and you should get a
BadCertificate alert.

The Client Auth tests were not correctly setting the Protocol, so that this

Move the preparation of the client certificate to be post processing work
after reading the CertificateRequest message rather than pre processing
work prior to writing the Certificate message. As part of preparing the
client certificate we may discover that we do not have one available. If
we are also talking SSLv3 then we won't send the Certificate message at
all. However, if we don't discover this until we are about to send the
Certificate message it is too late and we send an empty one anyway. This
is wrong for SSLv3.
