[PATCH 0/5] refactor unpack-trees

[Stefan Beller <sbeller@google.com>]

unpack-trees is a central file needed for the understanding
of working tree manipulation. To help with the understanding
refactor the code to be more readable.

The first patch was a standalone patch 8 days ago;
now incorporated into this series as a v3,
reducing the scope of the checkout state.

The second patch removes a single continue statement;
it needed some digging to explain, but looks trivial.

The last 3 patches shorten the check_updates function by adding more
functions. If we ever want to parallelize file IO then these smaller
functions would be the scope to do it, keeping the check_updates as
a high level function guiding through the steps what is happening during
a working tree update.

Thanks,
Stefan
