applications if they were passing a bogus 'flags' parameter yet having
things work as they wanted anyway.

dsa_mod_exp() and bn_mod_exp() handlers from dsa_do_verify() and
dsa_sign_setup(). When another DSA_METHOD implementation does not define
these lower-level handlers, it becomes impossible to do a fallback to
software on errors using a simple DSA_OpenSSL()->fn(key).

This change allows the default DSA_METHOD to function in such circumstances
by only using dsa_mod_exp() and bn_mod_exp() handlers if they exist,
otherwise using BIGNUM implementations directly (which is what those
handlers did before this change). There should be no noticable difference
for the software case, or indeed any custom case that didn't already
segfault, except perhaps that there is now one less level of indirection in
all cases.

- bugfix: in ECDH_compute_key, pad x coordinate with leading zeros if necessary

the buffer pointer.

Rename PKCS7_PARTSIGN to PKCS7_STREAM.

Guess what that's for :-)

rearrange some of the other text for better readability.

when reading from a non blocking BIO.

It would incorrectly interpret retries as EOF, incorrectly
buffer initial data and have no buffering at all after initial
data (data would be sent one byte at a time to EVP_DecodeUpdate).

An advisory will be posted to the web.  Expect a release within the hour.

to do it.

Note: this has only been tested on GNU-based platforms (Linux), and
needs to be tested on all others.  Additionally, it's not yet
supported on the following platforms, for lack of information:

Darwin (MacOS X)
Cygwin
OSF1/Alpha
SVR3
ReliantUNIX

Please help out with testing and the platforms we don't yet know well
enough.

looking at the MIT source.

Edit asn1.h so the new error code is the same in 0.9.7
and 0.9.8, rebuild new error codes.
