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.

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)
