The OpenSSL "RSA" object is currently 408 bytes compares to the ASN.1 encoding
which is 140 for a 1024 RSA key.
We save 268 bytes per descriptor (routerinfo_t) *and* microdescriptor
(microdesc_t). Scaling this to 6000 relays, and considering client usually
only have microdescriptors, we save 1.608 MB of RAM which is considerable for
mobile client.
This commit makes it that we keep the RSA onion public key (used for TAP
handshake) in ASN.1 format instead of an OpenSSL RSA object.
Changes is done in both routerinfo_t and microdesc_t.

By removing Tor2Web, there is no way a client can be non anonymous so we
remove that function and the callsites.

Because we just removed Tor2web support, the need_specific_rp is not needed
anymore when cannibalizing a circuit.

No behaviour change.
A previous fix to chutney removed v3 onion services from the
mixed+hs-v23 network, so seeing "mixed+hs-v23" in tests is
confusing.
Fixes bug 27345; bugfix on 0.3.2.1-alpha.
LinkAuth method 1 is the one where we pull the TLS master secrets
out of the OpenSSL data structures and authenticate them with
RSA. Right now we list method 1 as required for clients and relays.
That's a problem, since we can't reasonably support it with NSS. So
let's remove it as a requirement and a recommendation.
As for method 3: I'd like to recommend it it, but that would make
0.2.9 start warning. Let's not do that till at least some time
after 0.3.5 (the next LTS) is stable.
Closes ticket 27286
Instead, count exits as usable if they have the exit flag, and
present if they also have a non-reject exit policy.
Requiring a threshold of usable descriptors avoids directories trickling
exit descriptors to clients to discover their ExitNodes settings.
