Before, this function meant "can we connect to this node and
authenticate it using its ed25519 key?" Now it can additionally
mean, "when somebody else connects to this node, do we expect that
they can authenticate using the node's ed25519 key"?
This change lets us future-proof our link authentication a bit.
Closes ticket 20895. No backport needed, since ed25519 link
authentication support has not been in any LTS release yet, and
existing releases with it should be obsolete before any releases
without support for linkauth=3 are released.
Version 3 hidden service needs rendezvous point that have the protocol version
HSRend >= 2 else the rendezvous cells are rejected.

In Nick's words:
"We want to always return false if the platform is a Tor version, and it
is not as new as 0.3.0.8 -- but if the platform is not a Tor version, or
if the version is as new as 0.3.0.8, then we want to obey the protocol
list.
That way, other implementations of our protocol won't have to claim any
particular Tor version, and future versions of Tor will have the freedom
to drop this protocol in the distant future."
These statistics were largely ununsed, and kept track of statistical information
on things like how many time we had done TLS or how many signatures we had
verified. This information is largely not useful, and would only be logged
after receiving a SIGUSR1 signal (but only if the logging severity level was
less than LOG_INFO).
* FIXES#19871.
* REMOVES note_crypto_pk_op(), dump_pk_op(), and pk_op_counts from
src/or/rephist.c.
* REMOVES every external call to these functions.
Note down in the routerstatus_t of a node if the router supports the HSIntro=4
version for the ed25519 authentication key and HSDir=2 version for the v3
descriptor supports.

strto* and _atoi64 accept +, -, and various whitespace before numeric
characters. And permitted whitespace is different between POSIX and Windows.
Fixes bug 21507 and part of 21508; bugfix on 0.0.8pre1.
Fix for TROVE-2017-001 and bug 21278.
(Note: Instead of handling signed ints "correctly", we keep the old
behavior, except for the part where we would crash with -ftrapv.)
