fa13cf6996 Repair: do not mark deleted when upstream object is not found
With the previous behaviour, repairing could see some data as absent
and decide that the object or version was deleted,
thus going on to delete the version and blocks.
In the case where read_quorum + write_quorum <= replication_factor
however, entries may not yet be returned by the get, thus data would
have been deleted that should hot have been. The new behavior is more
cautious and just skips the entry when the warning is emitted.

b46a7788d1 Implement HTTP ranges in get 2020-05-04 13:09:23 +00:00
16fbb32fd3 Rate limit requests a bit more seriously
droping the slot later (after reading the request response)
means that we aren't freeing our quota slot,
so the maximum number of simultaneous requests now also counts the
response reading phase

TODO next: quotas per rpc destination node, or maybe per datacenter (?)

3324971701 Slightly improved S3 compatibility
- ListBucket does not require any of the parameters (delimiter,
    prefix, max-keys, etc)
- URLs are properly percent_decoded
- PutObject and DeleteObject calls now answer correctly
    (empty body, version id in the x-amz-version-id: header)

e41ce4d815 Implement getting missing blocks when RC increases
Issue: RC increases also when the block ref entry is first put by the actual client.
At that point the client is probably already sending us the block content,
so we don't need to do a get...
We should add a delay before the task is added or find something to do.

d2814b5c33 TLS works \o/
So, the issues were:
- webpki does not support IP addresses as DNS names in URLs,
  so I hacked the HttpsConnector to always provide a fixed string
  as the DNS name for server certificate validation
- the certificate requied a SAN section which was complicated to build
  but eventually the solution is there in genkeys.sh

3477864142 Fix the Sync issue. Details:
So the HTTP client future of Hyper is not Sync, thus the stream
that read blocks wasn't either. However Hyper's default Body type
requires a stream to be Sync for wrap_stream. Solution: reimplement
a custom HTTP body type.
