v6: When a file is unlocked but has not been modified, and the unlocking is
only staged, git-annex add did not lock it. Now it will, for consistency
with how modified files are handled and with v5.
Note the removal of the sameInodeCache check. Otherwise it would see
that the unmodified file is unmodified and stop there. That check seems to have
been copied from the direct mode branch. But, direct mode had a specific
reason to check for unmodified content, that does not apply to v6.
The second pass means there is potential for a race, eg the unlocked
file could be modified in between the first and second passes.
No problem with that, since both passes do the same thing.

* Don't use GIT_PREFIX when GIT_WORK_TREE=. because it seems git
does not intend GIT_WORK_TREE to be relative to GIT_PREFIX in that
case, despite GIT_WORK_TREE=.. being relative to GIT_PREFIX.
* Don't use GIT_PREFIX to fix up a relative GIT_DIR, because
git 2.11 sets GIT_PREFIX set to a path it's not relative to.
and apparently GIT_DIR is never relative to GIT_PREFIX.
Commit e50ed4ba48 led us down this path
by working around a git bug by relying on the barely documented GIT_PREFIX.

v6: Fix annex object file permissions when git-annex add is run on a
modified unlocked file, and in some related cases.
If a hard link is made, don't freeze it; annex.thin
uses writable object files.
Also: For some reason, linkToAnnex used to thawContent src. I can see no
reason why it needed to do that, so I eliminated that.

Probably not noticed until now because the queue is large enough that two
threads each filling theirs at the same time and flushing is unlikely to
happen.
Also made explicit that each worker thread gets its own queue.
I think that was the case before, but if something was put in the queue
before worker threads were forked off, they could have each inherited the
same queue.
Could have gone with a single shared queue, but per-worker queues is more
efficient, because a worker can add lots of stuff to its own queue without
any locking.
