33b1a33c33 Add rendcache.{c|h}
For now, rend_cache_entry_t has been moved from or.h to rendcache.h and
those files have been added to the build system.

In the next commit, these will contain hidden service descriptor cache ABI
and API for both client and directory side. The goal is to consolidate the
descriptor caches in one location to ease development, maintenance, review
and improve documentation for each cache behavior and algorithm.

b6eee531bb Support encrypted offline master keys with a new --keygen flag
When --keygen is provided, we prompt for a passphrase when we make a
new master key; if it is nonempty, we store the secret key in a new
crypto_pwbox.

Also, if --keygen is provided and there *is* an encrypted master key,
we load it and prompt for a passphrase unconditionally.

We make a new signing key unconditionally when --keygen is provided.
We never overwrite a master key.

592a439107 Tie key-pinning logic into directory authority operation
With this patch:
  * Authorities load the key-pinning log at startup.
  * Authorities open a key-pinning log for writing at startup.
  * Authorities reject any router with an ed25519 key where they have
    previously seen that ed25519 key with a different RSA key, or vice
    versa.
  * Authorities warn about, but *do not* reject, RSA-only descriptors
    when the RSA key has previously gone along with an Ed25519 key.
    (We should make this a 'reject' too, but we can't do that until we're
    sure there's no legit reason to downgrade to 0.2.5.)

eacbe03c71 Key-pinning back-end for directory authorities.
This module implements a key-pinning mechanism to ensure that it's
safe to use RSA keys as identitifers even as we migrate to Ed25519
keys.  It remembers, for every Ed25519 key we've seen, what the
associated Ed25519 key is.  This way, if we see a different Ed25519
key with that RSA key, we'll know that there's a mismatch.

We persist these entries to disk using a simple format, where each
line has a base64-encoded RSA SHA1 hash, then a base64-endoded
Ed25519 key.  Empty lines, misformed lines, and lines beginning with
a # are ignored. Lines beginning with @ are reserved for future
extensions.

fe5d2477aa Implement ed25519-signed descriptors
Now that we have ed25519 keys, we can sign descriptors with them
and check those signatures as documented in proposal 220.

818e6f939d prop220: Implement certificates and key storage/creation
For prop220, we have a new ed25519 certificate type. This patch
implements the code to create, parse, and validate those, along with
code for routers to maintain their own sets of certificates and
keys.  (Some parts of master identity key encryption are done, but
the implementation of that isn't finished)
