Ic common cooking

add git specific stuff to ic_common and re-tag
Here I'll try to add stuff to R194 and to retag it as R194-git

get the hash of refs/tags/R194
git ls-remote origin | grep R194 cb4b2f4b9794e1ad2ac15df0aa8f3e980ab1e030       refs/tags/R194

checkout to a local branch
git checkout cb4b2f4b9794e1ad2ac15df0aa8f3e980ab1e030 -b local_cvs_to_git_R194

create a patch
git format-patch -M -C -s --keep-subject -o 2009_07_22-0001-to_amou-cvs_to_git  e.g. git format-patch -M -C -s --keep-subject -o 2009_07_22-0001-to_amou-cvs_to_git cb4b2f4b9794e1ad2ac15df0aa8f3e980ab1e030 git tag -f 2009_07_16-0001-to_amou-cvs_to_git
