Merge branch 'sdmf-partial-2'

This cleans up the mutable-retrieve code a bit, and should fix some
corner cases where an offset/size combinations that reads the last byte
of the file (but not the first) could cause an assert to fire, making
the download hang. Should address ticket:2459 and ticket:2462.

test_mutable: more enhancements

mutable/retrieve.py: rewrite partial-read handling

This should tolerate offset/size combinations that read the last byte of
the file, something which was broken before. It quits early in the case
of zero-byte reads, to simplify the resulting "which segments do I need"
logic. Probably addresses ticket:2459.

The Docker build process seems to use 'git pull --depth=1', which

can't compute a version (then 'tahoe --version' reports "unknown").
Pulling a hundred commits should be enough to see a tag without making
the resulting image unnecessarily large. If we go more than 100 commits
between tags, we'll need to increase this, or come up with something
smarter.
