some of these ought to have been noticed by the "misspell" tool, so if anybody is debugging it, here are some bug reports :)

2018-01-31hs-v3: Remove a BUG() when storing a descriptor in the client cacheDavid Goulet
It is possible in normal circumstances that a client fetches a descriptor that has a lower revision counter than the one in its cache. This can happen due to HSDir desync. Fixes #24976 Signed-off-by: David Goulet <dgoulet@torproject.org>

2017-11-20hs-v3: Add an encoded descriptor client cache lookup functionDavid Goulet
This commit adds hs_cache_lookup_encoded_as_client() function that returns the encoded descriptor for a given service public key. This will be needed by the "GETINFO hs/client/desc/id/<ADDR>" control port command. Signed-off-by: David Goulet <dgoulet@torproject.org>
2017-09-13prop224: Set stricter expiration time of cached client descriptors.George Kadianakis
In #23466 we discovered that cached descriptors can stay around on the client-side for up to 72 hours. In reality we only want those descs to get cached for the duration of the current time period, since after that TP is gone the client needs to compute a new blinded key to use for the HS. In this commit we start using the consensus time (if available) when cleaning up cached client descriptor entries. That makes sense because the client uses consensus time anyway for connecting to hidden services (e.g. computing blinded keys and time periods). If no recent consensus is available, we consider descriptors to be expired since we will want to fetch new ones when we get a live consensus to avoid the Roger bug. If we didn't do that, when Roger desuspends his laptop there would be a race between Tor fetching a new consensus, and Tor connecting to the HS which would still cause reachability issues. We also turned a rev counter check into a BUG, since we should never receive a descriptor with a strictly smaller rev counter than the one we already have, except if there is a bug or if the HSDir wants to mess with us. In any case, let's turn this into a BUG so that we can detect and debug such cases easily.

2017-08-24prop224: Add a client intro point state cacheDavid Goulet
This cache keeps track of the state of intro points which is needed when we have failures when using them. It is similar to the failure cache of the legacy system. At this commit, it is unused but initialized, cleanup and freed. Signed-off-by: David Goulet <dgoulet@torproject.org>

2016-12-16hs: Remove private keys from hs_desc_plaintext_data_t.J. Ryan Stinnett
Since both the client and service will use that data structure to store the descriptor decoded data, only the public keys are common to both. Fixes #20572. Signed-off-by: David Goulet <dgoulet@torproject.org>

It's possible for Tor to decide to exit before it's 100% done initializing. So, don't assert that the initialization is done.

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.
