mutable/retrieve.py: remove all bare assert()s

Replace them with _assert() or precondition(). Closes ticket:2462.

improve HTTP byte-range docs

webapi.rst: document Range: header on GET requests

IReadable.read(): document out-of-range errors

closes ticket#2461

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.
