Nick Mathewson 3885a2c05b tor-proto: add a backend to detect reported clock skew. 
NETINFO cells, which are sent in every handshake, may contain
timestamps.  This patch adds an accessor for the timestamp in the
Netinfo messages, and teaches the tor-proto code how to compute the
minimum clock skew in the code.

The computation isn't terribly precise, but it doesn't need to be:
Tor should work fine if your clock is accurate to within a few
hours.

This patch also notes a Y2038 problem in the protocol: see
torspec#80.

Part of #405.

Nick Mathewson 34c209c20e New documents to checkpoint my work on #329 and #87 
These documents explain how to profile arti for CPU and memory, and
how to simulate different kinds of breakage and misconfiguration.

They aren't at all in their final form, but I figure it's useful to
check them in so that more people can look at them, and make
suggestions.

Ian Jackson 8b8c2a426e humantime: Update to humantime-serde 1.1.1 
This has the humantime_serde::option module, which we have upstreamed

The remaining dependency with  version = "1"  is going to be removed
in a moment.

Nick Mathewson a98ae2a1f0 Canonicalize and intern protover lines on descriptors 
This should save around 1MB per consensus, since every relay has a
'protocols' lines, but there are only a few distinct possibilities
for such a line.

Closes #385.

Nick Mathewson 16f1bda324 Canonicalize and intern family representations to save memory.

Nick Mathewson e7c584f1b3 netdoc: Make versions smaller in GenericRouterStatus 
When the version is a Tor version, we can just parse it; otherwise,
we can intern it.  This shrinks GenericRouterStatus and avoids a lot
of extra help allocations.

Ian Jackson 1d281abaf8 Make ArtiConfigBuilder contain a TorClientConfigBuilder 
This is an API break: now one must use `.tor()` to access the Tor

But it is not a config file format break, because `#[serde(flatten)]`.
