[OE-core] [PATCH 0/5 V2]support incremental deb image generation

[Hongxu Jia]

Change from V1: fix do_rootfs error while using dash as default shell

The following is the test case about how to test incremental deb image
generation:

1, Modify a package 
1) Add the follow config option to a conf file:
    INC_DEB_IMAGE_GEN = "1"
    PACKAGE_CLASSES = "package_deb"

2) Run `bitbake core-image-sato' and test the image could work correctly.

3) Modify a package, such as busybox_1.20.2.bb.

4) Run `bitbake core-image-sato'

5) vim log.do_rootfs to see if the following log exists:
    `NOTE: Updating ***'

6) runqemu qemux86

2, Remove a package
1) Add the following line to conf/local.conf:
    INC_DEB_IMAGE_GEN = "1"
    PACKAGE_CLASSES = "package_deb"

2) Run "bitbake core-image-sato" to build an image

3) Comment out IMAGE_FEATURES in /meta/recipes-sato/images/core-image-sato.bb

4) Run "bitbake core-image-sato" to build an image

5) vim log.do_rootfs to see if the following log exists:
    `NOTE: Removing ***'

3, Add a package 
1) Add the following line to conf/local.conf:
    INC_DEB_IMAGE_GEN = "1"
    PACKAGE_CLASSES = "package_deb"
2) Do the above removing case.

3) Uncomment IMAGE_FEATURES in /meta/recipes-sato/images/core-image-sato.bb

4) Run `bitbake core-image-sato' to build an image

5) runqemu qemux86
