This implements the proposal 224 directory descriptor cache store and lookup
functionalities. Furthermore, it merges the OOM call for the HSDir cache with
current protocol v2 and the new upcoming v3.
Add hs_cache.{c|h} with store/lookup API.

In order to implement proposal 224, we need the data structure rend_data_t to
be able to accomodate versionning that is the current version of hidden
service (2) and the new version (3) and future version.
For that, we implement a series of accessors and a downcast function to get
the v2 data structure. rend_data_t becomes a top level generic place holder.
The entire rend_data_t API has been moved to hs_common.{c|h} in order to
seperate code that is shared from between HS versions and unshared code (in
rendcommon.c).

One is fixed by disabling the -Wredundant-decls warnings around
openssl headers here, because of the old double-declaration of
SSL_get_selected_srtp_profile().
One is fixed by including compat.h before or.h so that we get the
winsock2.h include before the windows.h include.
This was a stopgap method, designed on the theory that some routers
might support it before they could support Ed25519. But it looks
like everybody who supports RFC5705 will also have an Ed25519 key,
so there's not a lot of reason to have this even supported.
This patch moves the pregenerated RSA key logic into a new
testing_rsakeys.c.
Also, it adds support for RSA2048, since the link handshake tests
want that.
Also, it includes pregenerated keys, rather than trying to actually
generate the keys at startup, since generating even a small handful
of RSA2048 keys makes for an annoying delay.
In particular, these functions are the ones that set the identity of
a given connection or channel, and/or confirm that we have learned
said IDs.
There's a lot of stub code here: we don't actually need to use the
new keys till we start looking up connections/channels by Ed25519
IDs. Still, we want to start passing the Ed25519 IDs in now, so it
makes sense to add these stubs as part of 15055.
Also, adjust signing approach to more closely match the signing
scheme in the proposal.
(The format doesn't quite match the format in the proposal, since
RSA signatures aren't fixed-length.)
Closes 19020.
passthrough_test_setup doesn't pass through arguments if the argument
is equal to 0 or TT_SKIP. Instead, it fails or skips the test.
Assert on this, so we don't accidentally fail or skip tests.
ome policies are default-reject, some default-accept. But
policy_is_reject_star() assumed they were all default_reject. Fix
that!
Also, document that policy_is_reject_star() treats a NULL policy as
empty. This allows us to simplify the checks in
parse_reachable_addresses() by quite a bit.
Fxes bug 20306; bugfix on 0.2.8.2-alpha.
