[OE-core] [PATCH V2 0/2] read-only rootfs support

[Qi.Chen at windriver.com]

From: Chen Qi <Qi.Chen at windriver.com>

Add read-only rootfs support to sysvinit startup system.
The main changes are:
1) Let rootfs_xxx.bbclass support 'read-only-rootfs' image feature.
   If IMAGE_FEATURES contains 'read-only-rootfs', then the populate-volatile.sh
   script is run at rootfs time to set up basic directories and files.
2) Improve the populate-volatile.sh init script.
3) Add two config files specific to read-only-rootfs image, which are to be used
   by the populate-volatile.sh script.
4) Automatically adjust the mount options in fstab when 'read-only-rootfs' is in
   IMAGE_FEATURES.

Version 2 fixes a problem version one has, that is, if we build an image without
'read-only-rootfs' image feature after we built one that has this feature, the
mount options in fstab is wrong.
