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.

52d5f4da12 Avoid spurious error logs when using NSS
The tls_log_errors() function now behaves differently for NSS than
it did for OpenSSL, so we need to tweak it a bit.

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.

5205c7fd90 Initial NSS support for TLS.
This is enough to get a chutney network to bootstrap, though a bunch
of work remains.

c567b8fcb4 NSS support for x509 certs

8148c0717d Change log_test_helpers macros to use printf, not pasting
This ensures that our test failure messages actually tell us what
strings Tor was expecting.  I will need this to debug some test
failures.

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.

Note that this patch causes a couple of places that still assumed
OpenSSL to be disabled when NSS is enabled
   - tor-gencert
   - pbkdf2

1992c76130 Split tls modules and their tests into openssl and generic.
Also, add a stubbed-out nss version of the modules.  The tests won't
pass with NSS yet since the NSS modules don't do anything.

This is a good patch to read with --color-moved.

b94e7de7db Refactor crypto_rsa to use pem module.
This cleans up a lot of junk from crypto_rsa_openssl, and will
save us duplicated code in crypto_rsa_nss (when it exists).

(Actually, it already exists, but I am going to use git rebase so
that this commit precedes the creation of crypto_rsa_nss.)

0f971d7c91 Rename functions that encode/decode private keys
It is not nice to expose a private key's contents without having the
function name advertise the fact.  Fortunately, we weren't misusing
these yet.
