864c42f4d6 Count HTTP 503 as a download failure.
Because as Teor puts it: "[Resetting on 503] is exactly what we
don't want when relays are busy - imagine clients doing an automatic
reset every time they DoS a relay..."

Fixes bug 20593.

858867a31a Allow infinitely long delays in exponential-backoff downloads
It's only safe to remove the failure limit (per 20536) if we are in
fact waiting a bit longer each time we try to download.

Fixes bug 20534; bugfix on 0.2.9.1-alpha.

When downloading certificates, check for related failures
If a consensus expires while we are waiting for certificates to download,
stop waiting for certificates.

If we stop waiting for certificates less than a minute after we started
downloading them, do not consider the certificate download failure a
separate failure.

Fixes bug 20533; bugfix on commit e0204f21 in 0.2.0.9-alpha.

Ensure relays don't make multiple connections during bootstrap
Relays do not deliberately launch multiple attempts, so the impact of this
bug should be minimal. This fix also defends against bugs like #20499.

Bugfix on 0.2.8.1-alpha.

09c750cce3 Check the correct key when checking RSA crosscert in hs_descriptor.c
Note that the "signed key" in the signing key certificate is the
signing key.  The "signing key" in the  signing key certificate is
the key that signs the certificate -- that is, the blinded key.

dbd01590cc Fix an assertion failure in hs_cache_free_all().
It's possible for Tor to decide to exit before it's 100% done
initializing.  So, don't assert that the initialization is done.

1517a8a2eb Add EnableOnionServicesV3 consensus parameter
This parameter controls if onion services version 3 (first version of prop224)
is enabled or not. If disabled, the tor daemon will not support the protocol
for all components such as relay, directory, service and client. If the
parameter is not found, it's enabled by default.

025610612d prop224: Directory cache support
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.

8293356ad9 hs: Refactor rend_data_t for multi version support
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).
