Add script to make stable compat-wireless releases

To make stable compat-wireless releases we make use of
hpa's linux-2.6-allstable.git tree:

git://git.kernel.org/pub/scm/linux/kernel/git/hpa/linux-2.6-allstable.git

With scripts/gen-stable-release.sh and the linux-2.6-allstable.git
tree present you can make stable kernel compat-wireless releases.
By default we target rc kernels. If you want to use as base another
kernel that must be specified.

Examples usages:

./scripts/gen-stable-release.sh
./scripts/gen-stable-release.sh linux-2.6.29.y
./scripts/gen-stable-release.sh linux-2.6.30.y
