Make read-only rootfs work with live images

From: Chen Qi <[email protected]>

Changes from V4:
1. Fix the error of 'read -f' in populate-volatile.sh. The '-f' should should not be there.
2. Fix the error of missing colon in populate-volatile.sh.

Changes from V3:
1. Take hidden directories and files into consideration when copying before bind mounting.
2. Use 'cp -a' in populate-volatile.sh to avoid potential problems

Change from V2:
1. modify the irda init script so that it doesn't necessarily need to write to /etc/sysconfig/irda
2. drop the lighttpd patch
3. modify the logic for openssh in case of a read-only rootfs

Change from V1:
1. Disable the generating of ssh keys at rootfs time
2. Add a mechanism to read-only-rootfs-hook.sh to check whether a directory is on a read-only partition.
3. Fix a new bug#4937 (https://bugzilla.yoctoproject.org/show_bug.cgi?id=4937)
