initialised for use, but one of the useful things about ENGINE_ctrl()
is that it can be a useful way to provide settings that should be
used during initialisation. Instead, I've altered the code to insist
that the engine has a valid *structural* reference (rather than a
*functional* one).

(a) a couple of typos in the source code

(b) adds a ctrl command and handling code to enable or disable the fork()
    checking that CHIL can do when applications are calling fork() in
    their application and using the library from multiple child processes
    after the one initialisation.

(c) adds another ctrl command to prevent the initialisation of the CHIL
    library from providing mutex-handling callbacks, even if the library
    has suitable callbacks already available. This can simplify (and
    optimise) applications that do not use multi-threading.

In s23_clnt.c, don't use special rollback-attack detection padding

SSL 2.0 is the only protocol enabled in the server.

New ASN1_STRING_print_ex() and X509_NAME_print_ex()
functions. These are intended to be replacements
for the ancient ASN1_STRING_print() and X509_NAME_print()
functions.

The new functions support RFC2253 and various pretty
printing options. It is also possible to display
international characters if the terminal properly handles
UTF8 encoding (Linux seems to tolerate this if the
"unicode_start" script is run).

Still needs to be documented, integrated into other
utilities and extensively tested.

size) through the base64 filter, b64_write() messes up it's parameters
in such a way that instead of writing correct base64 output, the first
4 characters of that output is repeated over and over.  This fix
corrects that problem.

it wants to stir the pool using ssleay_rand_add.  This fix provides the
possibility to call ssleay_rand_add inside a locked state by simply telling
it not to do any locking through a static variable.  This isn't the most
elegant way one could do this, but it does retain thread safety during the
stirring process.

has helped me a bit when I ran into trouble.

there's support for building under Linux and True64 (using examples
from the programming manuals), including versioning that is currently
the same as OpenSSL versions but should really be a different series.

With this change, it's up to the users to decide if they want shared
libraries as well as the static ones.  This decision now has to be
done at configuration time (well, not really, those who know what they
do can still do it the same way as before).

The OpenSSL programs (openssl and the test programs) are currently
always linked statically, but this may change in the future in a
configurable manner.  The necessary makefile variables to enable this
are in place.

Also note that I have done absolutely nothing about the Windows target
to get something similar.  On the other hand, DLLs are already the
default there, but without versioning, and I've no idea what the
possibilities for such a thing are there...
