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)

crawler: fix performance problems: only save state once per timeslice (not after every bucket), don't start the crawler until 5 minutes after node startup

BucketCountingCrawler: store just the count, not cycle+count, since it's too easy to make usage mistakes otherwise

crawler: load state from the pickle in init, rather than waiting until startService, so get_state() can be called early

BucketCountingCrawler: rename status and state keys to use 'bucket' instead of 'share', because the former is more accurate

storage: also report space-free-for-root and space-free-for-nonroot, since that helps users understand the space-left-for-tahoe number better

change StorageServer to take nodeid in the constructor, instead of assigning it later, since it's cleaner and because the original problem (Tubs not being ready until later) went away
