Subject: Move common-functions.sh and git-checkout.sh into lib
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=172c7565a6a3ea31821f84fbd0f2b6aaea35deab;p=raisin.git

Move common-functions.sh and git-checkout.sh into lib

"script" implies something which is designed to be run standalone.

"lib" implies that this is going to be sourced from another bash script.

Also change "git-checkout" to be a function rather than a script
