When printing out an ASN.1 structure if the type is an item template don't
fall thru and attempt to interpret as a primitive type.

In the RSA_X931_derive_ex a call to BN_CTX_new is made. This can return
NULL on error. However the return value is not tested until *after* it is
derefed! Also at the top of the function a test is made to ensure that
|rsa| is not NULL. If it is we go to the "err" label. Unfortunately the
error handling code deref's rsa.

If SSL_check_chain is called with a NULL X509 object or a NULL EVP_PKEY
or the type of the public key is unrecognised then the local variable
|cpk| in tls1_check_chain does not get initialised. Subsequently an
attempt is made to deref it (after the "end" label), and a seg fault will
result.

The call to asn1_do_adb can return NULL on error, so we should check the

ASN1_primitive_new takes an ASN1_ITEM * param |it|. There are a couple
of conditional code paths that check whether |it| is NULL or not - but
later |it| is deref'd unconditionally. If |it| was ever really NULL then
this would seg fault. In practice ASN1_primitive_new is marked as an
internal function in the public header file. The only places it is ever
used internally always pass a non NULL parameter for |it|. Therefore, change
the code to sanity check that |it| is not NULL, and remove the conditional
checking.

Calling EVP_DigestInit_ex which has already had the digest set up for it
should be possible. You are supposed to be able to pass NULL for the type.
However currently this seg faults.

In the event of an error |rr| could be NULL. Therefore don't assume you can

Configure would load the glob "Configurations*".  The problem with
this is that it also loads all kinds of backups of those
configurations that some editors do, like emacs' classic
'Configurations~'.  The solution is to give them an extension, such as
'.conf', and make sure to end the glob with that.

Also, because 'Configurations.conf' makes for a silly name, and
because a possibly large number of configurations will become clutter,
move them to a subdirectory 'Configurations/', and rename them to
something more expressive, as well as something that sets up some form
of sorting order.  Thus:

    Configurations	->	Configurations/10-main.conf
    Configurations.team	->	Configurations/90-team.conf

Finally, make sure that Configure sorts the list of files that 'glob'
produces, and adapt Makefile.org.

Fix security issue where under certain conditions a client can complete a
handshake with an unseeded PRNG. The conditions are:
- Client is on a platform where the PRNG has not been seeded, and the
user has not seeded manually
- A protocol specific client method version has been used (i.e. not
SSL_client_methodv23)
- A ciphersuite is used that does not require additional random data
from the PRNG beyond the initial ClientHello client random
(e.g. PSK-RC4-SHA)

If the handshake succeeds then the client random that has been used will
have been generated from a PRNG with insufficient entropy and therefore
the output may be predictable.

For example using the following command with an unseeded openssl will
succeed on an unpatched platform:

openssl s_client -psk 1a2b3c4d -tls1_2 -cipher PSK-RC4-SHA

Since commit 741c9959 ("DTLS revision."), we put the wrong protocol
version into our ClientHello for DTLS1_BAD_VER. The old DTLS
code which used ssl->version was replaced by the more generic SSL3 code
which uses ssl->client_version. The Cisco ASA no longer likes our
ClientHello.
