22e2403145 Revert "Avoid double-close on TCP sockets under NSS." 
This reverts commit b5fddbd241.

The commit here was supposed to be a solution for #27451 (fd
management with NSS), but instead it caused an assertion failure.

Fixes bug 27500; but not in any released Tor.

8cd091a8d3 Add a last-ditch memwipe() implementation for nss+old glibc 
On new glibc versions, there's an explicit_bzero().  With openssl,
there's openssl_memwipe().

When no other approach works, use memwipe() and a memory barrier.

600e046ed3 Rename crypto_pk_check_key(), use it more reasonably, add tests 
This function was a wrapper around RSA_check_key() in openssl, which
checks for invalid RSA private keys (like those where p or q are
composite, or where d is not the inverse of e, or where n != p*q).
We don't need a function like this in NSS, since unlike OpenSSL, NSS
won't let you import a bogus private key.

I've renamed the function and changed its return type to make it
more reasonable, and added a unit test for trying to read a key
where n != p*q.

dd04fc35c6 Remove tor_tls_shutdown() 
This function was supposed to implement a half-duplex mode for our
TLS connections.  However, nothing in Tor actually uses it (besides
some unit tests), and the implementation looks really questionable
to me.  It's probably best to remove it.  We can add a tested one
later if we need one in the future.

6a88d8f6b4 When enabling NSS, disable OpenSSL. 
We used to link both libraries at once, but now that I'm working on
TLS, there's nothing left to keep OpenSSL around for when NSS is
enabled.

OpenSSL to be disabled when NSS is enabled

   - pbkdf2

This cleans up a lot of junk from crypto_rsa_openssl, and will

that this commit precedes the creation of crypto_rsa_nss.)

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.

3a45f6ffe9 Implementation for a simple order-preserving encryption scheme. 
This is meant for use when encrypting the current time within the

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.
