b3416476b4 Remove all uses of weak_rng. 
I'm not removing the weak_rng code itself yet, since it is possible
that we will want to revert one of these.

b25cd5cfe1 Implement code to manage a per-thread instance of crypto_fast_rng() 
The subsystems API makes this really simple, fortunately.

4417ac880a Fix a compiler warning on OpenBSD 
malloc_options needs to be declared extern (and declaring it extern
means we need to initialize it separately)

Fixes bug 29145; bugfix on 0.2.9.3-alpha

f3cbd6426c Implement a fast aes-ctr prng 
This module is currently implemented to use the same technique as
libottery (later used by the bsds' arc4random replacement), using
AES-CTR-256 as its underlying stream cipher.  It's backtracking-
resistant immediately after each call, and prediction-resistant
after a while.

Here's how it works:

We generate psuedorandom bytes using AES-CTR-256.  We generate BUFLEN bytes
at a time.  When we do this, we keep the first SEED_LEN bytes as the key
and the IV for our next invocation of AES_CTR, and yield the remaining
BUFLEN - SEED_LEN bytes to the user as they invoke the PRNG.  As we yield
bytes to the user, we clear them from the buffer.

Every RESEED_AFTER times we refill the buffer, we mix in an additional
SEED_LEN bytes from our strong PRNG into the seed.

If the user ever asks for a huge number of bytes at once, we pull SEED_LEN
bytes from the PRNG and use them with our stream cipher to fill the user's
request.

3d3578ab41 Extract RNG tests into a new test module 
test_crypto.c is pretty big; it wouldn't hurt to split it up some
more before I start adding stuff to the PRNG tests.
