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
