Log message:
Big thanks to Solar Designer who pointed out a bug in bcrypt
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
