Fixes to d2i_ASN1_OBJECT, ASN1_INTEGER_to_BN and a_strex.c

initialize ex_pathlen to -1 so it isn't checked if pathlen
is not present.

set ucert to NULL in apps/pkcs12.c otherwise it gets freed
twice.

remove extraneous '\r' in MIME encoder.

Allow a NULL to be passed to X509_gmtime_adj()


Make PKCS#7 code use definite length encoding rather then
the indefinite stuff it used previously.

found myself needing it a number of times, the latter for completeness.

MD4 implemented.  Assar Westerlund provided the digest code itself and the test utility, I added the bits to get a EVP interface, the command line utility and the speed test

building a complete chain.  Now added through the -CAfile and -CApath
arguments.

Add warning print out if duplicate names found:
should end up as a fatal error but a warning for
now until they problems are fixed...

Fix warnings with BIO_dump_indent().

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()
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.

'openssl asn1parse'.  As a side effect, the functions ASN1_parse_dump
and BIO_dump_indent are added.

ASN1_TIME fixes.

New function c2i_ASN1_OBJECT().

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...

Make req seed the PRNG if signing with
an already existing DSA key.

Document the new smime options.

call the i2c/c2i (they were not using the
content length for the headers).

Fix ASN1 long form tag encoding. This never
worked but it was never tested since it is
only used for tags > 30.

New options to smime program to allow the
PKCS#7 format to be specified and the content
supplied externally.

New ASN1 functions that just deal with
content octets, not tag+length.

The message to everyone is "Do not hack OpenSSL when stressed"...

(Still needs to be tested against the original using sample passwords
of different length.)

into lexical order. Previously it depended on
the order of files in the directory.

This should now mean that all systems will
agree on the order of safestack.h and will
not change it needlessly and avoid massive
needless commits to safestack.h in future.

It wont however avoid this one :-(

Fixes for Win32 build.

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 :-)

Handle ASN1_SET_OF and PKCS12_STACK_OF using function
casts in the same way as STACK_OF.

After some messing around this seems to work but needs
a few more tests. Working out the syntax for sk_set_cmp_func()
(cast it to a function that itself returns a function pointer)
was painful :-(

Needs some testing to see what other compilers think of this
syntax.

Also needs similar stuff for ASN1_SET_OF etc etc.

Documentation correction.

to support multiple calls.

New function to retrieve email address from certificates and
requests.

as expected -- maybe it's the different processor, maybe my
previous timings were too inaccurate.

Don't give performance gain estimates that appear to be more precise
than they really are, especially when they are wrong
(2/(1/1.15 + 1) = ca. 1.0698).

marginally faster BN_mod_exp for 1024 bit exponents.

because we're only handling words anyway) in BN_mod_exp_mont_word
making it a little faster for very small exponents,
and adjust the performance gain estimate in CHANGES according
to slightly more thorough measurements.
(15% faster than BN_mod_exp_mont for "large" base,
20% faster than BN_mod_exp_mont for small base.)
