* Automatically convert direct mode repositories to v7 with adjusted
unlocked branches and set annex.thin.
* init: When run on a crippled filesystem with --version=5,
will error out, since version 7 is needed for adjusted unlocked branch.
* direct: This command always errors out as direct mode is no longer
supported.
* indirect: This command has become a deprecated noop.
* proxy: This command is deprecated because it was only needed in direct
mode. (But it continues to work.)
Also removed mentions of direct mode throughough the documentation.
I have not removed all the direct mode code yet.
This allows bypassing the direct mode guard in a safe way to do all sorts
of things including git revert, git mv, git checkout ...

Direct mode repositories can now have core.bare=true set, to prevent
accidentally running git commands that try to operate on the work tree,
and so do the wrong thing.
This is not yet the default, and it causes known problems for git-annex sync
due to receive.denyCurrentBranch not working in bare repositories.

This was the last place in git-annex that could remove data referred to by
the git history, without being forced.
Like drop, dropunused checks remotes, and honors the global annex.numcopies
setting. (However, .gitattributes settings cannot apply to unused files.)
