Overly tight coding caused the password transformation loop to stop
examining input once it had processed a byte equal to 0x80. Thus, if the
given password string contained such a byte (which is possible though not
highly likely in UTF8, and perhaps also in other non-ASCII encodings), all
subsequent characters would not contribute to the hash, making the password
much weaker than it appears on the surface.
This would only affect cases where applications used DES crypt() to encode
passwords before storing them in the database. If a weak password has been
created in this fashion, the hash will stop matching after this update has
been applied, so it will be easy to tell if any passwords were unexpectedly
weak. Changing to a different password would be a good idea in such a case.
(Since DES has been considered inadequately secure for some time, changing
to a different encryption algorithm can also be recommended.)
This code, and the bug, are shared with at least PHP, FreeBSD, and OpenBSD.
Since the other projects have already published their fixes, there is no
point in trying to keep this commit private.
This bug has been assigned CVE-2012-2143, and credit for its discovery goes
to Rubin Xu and Joseph Bonneau.

This addresses only those cases that are easy to fix by adding or
moving a const qualifier or removing an unnecessary cast. There are
many more complicated cases remaining.

Few cleanups and couple of new things:
- add SHA2 algorithm to older OpenSSL
- add BIGNUM math to have public-key cryptography work on non-OpenSSL
build.
- gen_random_bytes() function
The status of SHA2 algoritms and public-key encryption can now be
changed to 'always available.'
That makes pgcrypto functionally complete and unless there will be new
editions of AES, SHA2 or OpenPGP standards, there is no major changes
planned.

At least it was now detected correctly.

produces garbage.
I learned the hard way that
#if UNDEFINED_1 == UNDEFINED_2
#error "gcc is idiot"
#endif
prints "gcc is idiot" ...
Affected are MD5/SHA1 in internal library, and also HMAC-MD5/HMAC-SHA1/
crypt-md5 which use them. Blowfish is ok, also Rijndael on at
least x86.
Big thanks to Daniel Holtzman who send me a build log which
contained warning:
md5.c:246: warning: `X' defined but not used
Yes, gcc is that helpful...
Please apply this.

Seems it is getting compileable...
