60705a5719 Use NSS in crypto_rand.c
This is comparatively straightforward too, except for a couple of
twists:

   * For as long as we're building with two crypto libraries, we
     want to seed _both_ their RNGs, and use _both_ their RNGs to
     improve the output of crypto_strongest_rand()

   * The NSS prng will sometimes refuse to generate huge outputs.
     When it does, we stretch the output with SHAKE.  We only need
     this for the tests.

f64c9dccde Use NSS's digest code in Tor.
This was a fairly straightforward port, once I realized which layer

c515dc8d0d Remove over-cleverness from our coverity BUG() definition.
Our previous definition implied that code would never keep running
if a BUG occurred (which it does), and that BUG(x) might be true
even if x was false (which it can't be).

Closes ticket 26890. Bugfix on 0.3.1.4-alpha.

3a45f6ffe9 Implementation for a simple order-preserving encryption scheme.
This is meant for use when encrypting the current time within the
period in order to get a monotonically increasing revision counter
without actually revealing our view of the time.

This scheme is far from the most state-of-the-art: don't use it for
anything else without careful analysis by somebody much smarter than
I am.

See ticket #25552 for some rationale for this logic.

d811ce2421 Add postfork support for nss
We need this in our unit tests, since otherwise NSS will notice
we've forked and start cussing us out.

I suspect we'll need a different hack for daemonizing, but this
should be enough for tinytest to work.

c8ccd028a7 Don't redefine str(n)casecmp on windows unless they're missing
When we do redefine them, use inline functions instead of #define.

This fixes a latent code problem in our redefinition of these
functions, which was exposed by our refactoring: Previously, we
would #define strcasecmp after string.h was included, so nothing bad
would happen.  But when we refactored, we would sometimes #define it
first, which was a problem on mingw, whose headers contain
(approximately):

inline int strcasecmp (const char *a, const char *b)
   { return _stricmp(a,b); }

Our define turned this into:
  inline int _stricmp(const char *a, const char *b)
    { return _stricmp(a,b); }

And GCC would correctly infer that this function would loop forever,
rather than actually comparing anything.  This caused bug 26594.

Fixes bug 26594; bug not in any released version of Tor.

7159edf909 Move the escape-for-log code into src/lib/log
It doesn't need anything higher-level, and everything that needs the
logs potentially needs this.

ebbb0348dc Finish renaming digestset_contains to digestset_probably_contains
Since bloom filters are probabilistic, it's nice to make it clear
that the "contains" operation can have false positives.

bf89278c79 Refactor bloom filter logic not to be digest-specific.
Now the address-set code and the digest-set code share the same
backend.

d7bd8cf3b6 Use raw_assert directly in smartlist_core
I had previously added a "#define tor_assert raw_assert" here, to
make code movement in the previous commit more clear.

b1de1e7a77 Extract core part of smartlist code into its own library.
The smartlist_core library now contains only the parts of smartlists
that are needed for the logging library.  This resolves the
circularity between "container" and "log".

The "containers" library still uses the logging code, and has the
higher-level smartlist functions.
