Abdelilah Essiari <aes@george.lbl.gov> reports that for very small
records, EVP_EncodeUpdate() may misbehave. This happens when there's
a record boundary between the two ending b64 equal signs, which makes
EVP_EncodeUpdate think there has been more than one EOF, and therefore
add an extra NUL at the end of the output buffer. This fix corrects
that problem.

A few corrections with the shared library support:
1. make sure libssl.so becomes dependent on libcrypto.so
2. correct a number of silly bugs in the solaris-shared target, and make
sure lib*.so also depends on libc.so.

Make it so we can dynamically enable memory allocation debugging through the
environment variable OPENSSL_DEBUG_MEMORY (existence is sufficient). At the
same time, it makes sure that CRYPTO_malloc_debug_init() gets expanded some-
where and thereby tested for compilation.

Fix SSL 2.0 rollback checking: The previous implementation of the
test was never triggered due to an off-by-one error.
In s23_clnt.c, don't use special rollback-attack detection padding
(RSA_SSLV23_PADDING) if SSL 2.0 is the only protocol enabled in the
client; similarly, in s23_srvr.c, don't do the rollback check if
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()

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.

There's a slight possibility that a is 0 in BN_sub_word(), and might

When data are written out in very small blocks (less than 3 bytes in

There's a deadlock when ssleay_rand_bytes is called the first time, since
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.

Redo and enhance the support for building shared libraries. Currently
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...

I got sick and tired of having to keep track of NIDs when such a thing
could be done automagically, much like the numbering in libeay.num and
ssleay.num. The solution works as follows:
- New object identifiers are inserted in objects.txt, following the
syntax given in objects.README.
- objects.pl is used to process obj_mac.num and create a new
obj_mac.h.
- obj_dat.pl is used to create a new obj_dat.h, using the data in
obj_mac.h.
This is currently kind of a hack, and the perl code in objects.pl
isn't very elegant, but it works as I intended. The simplest way to
check that it worked correctly is to look in obj_dat.h and check the
array nid_objs and make sure the objects haven't moved around (this is
important!). Additions are OK, as well as consistent name changes.

Change mkstack.pl so it now sorts each group
into lexical order. Previously it depended on
the order of files in the directory.
This should now mean that all systems will

needless commits to safestack.h in future.

This is mostly a work around for the old VC++ problem
that it treats func() as func(void).
Various prototypes had been added to 'compare' function
pointers that triggered this. This could be fixed by removing
the prototype, adding function pointer casts to every call or
changing the passed function to use the expected arguments.
I mostly did the latter.
The mkdef.pl script was modified to remove the typesafe
functions which no longer exist.
Oh and some functions called OPENSSL_freeLibrary() were
changed back to FreeLibrary(), wonder how that happened :-)
