documentation for making git add only annex when configured by annex.largefiles
Code change should be trvial, but not yet implemented. This
significantly complicated the task of documenting how git-annex works.
I'm not sure how useful the annex.gitaddtoannex confguration is after
this change; seems that if a user has an annex.largefiles they will want
it applied consistently. But the last thing I want to hear is more
complaining from users about git add doing something they don't want it
to.
There's a pretty high risk users who got used to the git add behavior
and don't have annex.largefiles configured will miss the NEWS and
complain bitterly about their suddenly bloated repositories. Oh well.
Removed outdated comments about the old behavior to avoid confusion.
I don't know if I've found all the places that griping spread to.

annex.gitaddtoannex configuration
Added annex.gitaddtoannex configuration. Setting it to false prevents
git add from usually adding files to the annex.
(Unless the file was annexed before, or a renamed annexed file is detected.)
Currently left at true; some users are encouraging it be set to false.

shouldAnnex: check isInodeKnown
Renamed unlocked files are now detected, and will always be
annexed, unless annex.largefiles disallows it.
This allows for git add's behavior to later be changed to otherwise
not annex files (whether by default or as a config option), without
worrying about the rename case.
This is not a major behavior change; annexing is still the default. But
there is one case where the behavior is changed, I think for the better:
touch f
git -c annex.largefiles=nothing add f
git add bigfile
git commit -m ...
mv bigfile f
git add f
Before, git-annex would see that f was previously not annexed,
and so the renamed bigfile content gets added to git. Now, it notices
that the inode is the one that bigfile used, and so it annexes it.
This potentially slows down git add a lot in some repositories because
of the poor performance of isInodeKnown when there are a lot of unlocked
files. Configuring annex.largefiles avoids the speed hit.

init: Fix a failure when used in a submodule on a crippled filesystem.
When the submodule's parent repo has an adjusted unlocked branch,
it gets cloned by git, but git checks out master. git annex init then
fails because it wants to enter the adjusted branch, but:
Aborting because that branch may have changes that have not yet reached master
Note that init actually then exits 0, leaving master checked out.
This could also happen, absent submodules, if the parent repo has
an adjusted unlocked branch, but it is not checked out. In the more common
case where that branch is checked out, the clone uses the same branch,
so no problem.
The choices to fix this:
* Init could delete the existing adjusted branch, and re-adjust.
But then running init inside an adjusted branch on a crippled filesystem
would lose any changes that have not been synced back to master.
* Init could sync any changes back to master, but that would be very surprising
behavior for it.
* Init could simply check out the existing adjusted branch. If the branch
is diverged from master, well, sync will sort that out later.
This mirrors the behavior of cloning a repo that has an adjusted branch
checked out that has not yet been synced back to master.
Picked this choice.
