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.

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.

Only use OpenSSL kdf support if it is present.
...
We have to check for ERR_load_KDF_strings() here, since that's the
only one that's actually a function rather than a macro.
Fixes compilation with LibreSSL. Fixes bug 26712; bug not in
any released Tor.

Rename torlog.[ch] to log.[ch]

Fun fact: these files used to be called log.[ch] until we ran into
conflicts with systems having a log.h file. But now that we always
include "lib/log/log.h", we should be fine.
