Jason Wessel - June 14, 2012, 3:09 a.m.
There is a strong desire to store the raw git trees in a pre-mirror
such that they can easily get updated externally as well as to contain
local branches.

This patch adds another type of pre-mirror rule that is "git" based.

The syntax looks like:
  PREMIRRORS_append := "\
     git://.*/.* git://${LAYERDIR}/downloads/git/ \n"

The syntax for typical tar.gz compressed git tree is:
  PREMIRRORS_append := "\
     git://.*/.* file://${LAYERDIR}/downloads/git/ \n"

The new pre-mirror type also requires the creation of the GITDIR at
the pre-mirror check time or the git clone and git checks will fail
with obscure errors.
