* 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.
Since v6 is not a usable repo version any longer, it's confusing to have
documentation that refers to it.

i found that most man pages only had references to the main git-annex
manpage, which i stillfind pretty huge and hard to navigate through.
i tried to sift through all the man pages and add cross-references
between relevant pages. my general rule of thumb is that links should
be both ways unless one of the pages is a more general page that would
become ridiculously huge if all backlinks would be added
(git-annex-preferred-content comes to mind).
i have also make the links one per line as this is how it was done in
the metadata pages so far.
i did everything but the plumbing, utility and test commands, although
some of those are linked from the other commands so cross-links were
added there as well.
