67ad0175cd server.py: get_latencies now reports percentiles _only_ if there are sufficient observations for the interpretation of the percentile to be unambiguous.
interfaces.py:  modified the return type of RIStatsProvider.get_stats to allow for None as a return value
NEWS.rst, stats.py: documentation of change to get_latencies
stats.rst: now documents percentile modification in get_latencies
test_storage.py:  test_latencies now expects None in output categories that contain too few samples for the associated percentile to be unambiguously reported.
fixes #1392

0dee2a6036 storage: add a lease-checker-and-expirer crawler, plus web status page.
This walks slowly through all shares, examining their leases, deciding which
are still valid and which have expired. Once enabled, it will then remove the
expired leases, and delete shares which no longer have any valid leases. Note
that there is not yet a tahoe.cfg option to enable lease-deletion: the
current code is read-only. A subsequent patch will add a tahoe.cfg knob to
control this, as well as docs. Some other minor items included in this patch:

 tahoe debug dump-share has a new --leases-only flag
 storage sharefile/leaseinfo code is cleaned up
 storage web status page (/storage) has more info, more tests coverage
 space-left measurement on OS-X should be more accurate (it was off by 2048x)
  (use stat .f_frsize instead of f_bsize)
