[PATCH v3 0/1] extra: new concept of extra components

This patch series introduces the concept of extra components. These are components which are not yet part of the core but are good enough for distributions to ship, and in fact, they already do.

This benefits everyone:

 1. Distribution packagers that just want to do `make install`
 2. People who download git's source code and just want to do
    `make install`
 3. Developers who have no idea what's production-level quality in
    contrib/ and just want to do `make install`.

For now they'll have to do `make install install-extra`. But if the result is deemed correct, we might choose to add "install-extra" to the "install" target.

The measuring stick I'm using to gauge if a component in contrib belongs in extra is simple: are we already running tests for them with 'make test'? If the answer is "yes, we do run tests", then the answer is "yes, it belongs in contrib".

We might want to move more components from contrib to extra once their tests are being run reliably.

And we might move some components from the core which aren't really part of the core to extra, like gitk, git-gui, git-p4, and git-svn.

For now only part of contrib/completion is graduated to the new area.

Since v2 I removed workdir from the list of graduates as Philippe Blain suggested.
