Add --temp and --stage=all options to checkout-index.
Sometimes it is convient for a Porcelain to be able to checkout all unmerged files in all stages so that an external merge tool can be executed by the Porcelain or the end-user. Using git-unpack-file on each stage individually incurs a rather high penalty due to the need to fork for each file version obtained. git-checkout-index -a --stage=all will now do the same thing, but faster.
