* openssl.c: Add 3des and AES support
* README.pgcrypto: list only supported ciphers for openssl
OpenSSL has pre-processor symbol OPENSSL_NO_AES, which
isn't that helpful for detecting if it _does_ exist.
Thus the hack with AES_ENCRYPT.

* Use error codes instead of -1
* px_strerror for new error codes
* calling convention change for px_gen_salt - return error code
* use px_strerror in pgcrypto.c

It was a bad style to begin with, and now several loops can be clearer.
* pgcrypto.c: Fix function comments
* crypt-gensalt.c, crypt-blowfish.c: stop messing with errno
* openssl.c: use px_free instead pfree
* px.h: make redefining px_alloc/px_realloc/px_free easier

0.9.7x have EVP_DigestFinal function which which clears all of
EVP_MD_CTX. This makes pgcrypto crash in functions which
re-use one digest context several times: hmac() and crypt()
with md5 algorithm.
Following patch fixes it by carring the digest info around
EVP_DigestFinal and re-initializing cipher.

is pgcrypto bug as it assumed too much about inner workings of OpenSSL.
Following patch stops pgcrypto using EVP* functions for ciphers and lets
it manage ciphers itself.
This patch supports Blowfish, DES and CAST5 algorithms.

failures on FreeBSD. This patch replaces uint -> unsigned.
This was reported by Daniel Holtzman against 0.4pre3 standalone
package, but it needs fixing in contrib/pgcrypto too.

salt generation code. He also urged using better random source
and making possible to choose using bcrypt and xdes rounds more
easily. So, here's patch:
* For all salt generation, use Solar Designer's own code. This
is mostly due fact that his code is more fit for get_random_bytes()
style interface.
* New function: gen_salt(type, rounds). This lets specify iteration
count for algorithm.
* random.c: px_get_random_bytes() function.
Supported randomness soure: /dev/urandom, OpenSSL PRNG, libc random()
Default: /dev/urandom.
* Draft description of C API for pgcrypto functions.
New files: API, crypt-gensalt.c, random.c
Marko Kreen
* remove support for encode() as it is in main tree now
* remove krb5.c
* new 'PX library' architecture
* remove BSD license from my code to let the general
PostgreSQL one to apply
* md5, sha1: ANSIfy, use const where appropriate
* various other formatting and clarity changes
* hmac()
* UN*X-like crypt() - system or internal crypt
* Internal crypt: DES, Extended DES, MD5, Blowfish
crypt-des.c, crypt-md5.c from FreeBSD
crypt-blowfish.c from Solar Designer
* gen_salt() for crypt() - Blowfish, MD5, DES, Extended DES
* encrypt(), decrypt(), encrypt_iv(), decrypt_iv()
* Cipher support in mhash.c, openssl.c
* internal: Blowfish, Rijndael-128 ciphers
* blf.[ch], rijndael.[ch] from OpenBSD
* there will be generated file rijndael-tbl.inc.

are now separate files "postgres.h" and "postgres_fe.h", which are meant
to be the primary include files for backend .c files and frontend .c files
respectively. By default, only include files meant for frontend use are
installed into the installation include directory. There is a new make
target 'make install-all-headers' that adds the whole content of the
src/include tree to the installed fileset, for use by people who want to
develop server-side code without keeping the complete source tree on hand.
Cleaned up a whole lot of crufty and inconsistent header inclusions.
