[PATCH 0/8] Untracked cache improvements

[Christian Couder <christian.couder@gmail.com>]

Following the previous RFC version of this patch series and the
related discussions, here is a new version that tries to improve the
untracked cache feature.

This patch series implements core.untrackedCache as a bool config
variable. When it's true git should always try to use the untracked
cache, and when false git should never use it.

Patchs 1/8 and 3/8 add some features that are missing.

Patch 2/8, which is new, adds an enum as suggested by Duy.

Patchs 4/8, 5/8 and 6/8 are some refactoring to prepare for patch 7/8
which implements core.untrackedCache.

Patch 7/8 is the result of squashing the last 3 patches of the RFC
series. As discussed this sacrifies backward compatibility for a
simpler interface.

Patch 8/8, which is new, add some tests.

So the changes compared to the RFC version are just small bug fixes
and patchs 2/8 and 8/8.

The patch series is also available there:
