Add the foundation for the PACKAGE_EXCLUDE support.
As part of this work, it was noticed that the PACKAGE_INSTALL and
PACKAGE_INSTALL_ATTEMPTONLY were still using he 'normal' version for
dependencies. This should no longer be necessary as of the change in the way
the complementary package groups (dev, dbg, ptest and others) are defined.
By making this change the dependency tree is more correct than before, and
gives the ability for manipulating PACKAGE_INSTALL and
PACKAGE_INSTALL_ATTEMPTONLY, while adjusting the dependencies at the same
time.
Warning messages will be generated if the user is trying to exclude a
package that was previously in the PACKAGE_INSTALL or
PACKAGE_INSTALL_ATTEMPTONLY variables.
(See additional commits for package manager specific support.)
Add documentation on PACKAGE_EXCLUDE and related variables.

If the rootfs is read-only and the ssh keys are not available at system
start-up, the init script will generate ssh keys into /etc/ssh, thus
causing a 'read-only file system' error.
In order for Yocto based image to work correctly for read-only rootfs,
we use the following logic for openssh.
If the rootfs is read-only and there are pre-generated keys under /etc/ssh,
we use the pre-generated keys. Note the pre-generated keys are mainly for
debugging or development purpose.
If the rootfs is read-only and there are no pre-generated keys under
/etc/ssh, we use /var/run/ssh as the location for ssh keys. That is, at
system boot-up, the generated ssh keys will put into /var/run/ssh.

Now that the makedevs supports using user/group names in the devcie
table files, and it uses passwd and group files under the rootfs which
is provided by the base-passwd package, we should let package installation
finish first, so that makedevs can get a correct mapping from user/group
names to uid/gid.
The check for existence of ${IMAGE_ROOTFS}/dev is removed. This is because
do_rootfs doesn't have 'nostamp' flag any more, so the do_rootfs task will
not be rerun for every build. Checking for the existence of ${IMAGE_ROOTFS}/dev
is not necessary any more. Besides, as base-files package also installs the
/dev directory, this checking does not serve as a good criteria.

If the spec file already exist, and has not been stored into pseudo's files.db,
it maybe cause rpmbuild src.rpm fail, so remove it before doing rpmbuild src.rpm.

This introduces a DISK_SIGNATURE variable that allows controlling the
32-bit MBR disk signature. By default it is set to an automatically
generated disk signature but it may by overridden in the image recipe
by setting DISK_SIGNATURE to a 8 digit hex string.
This DISK_SIGNATURE variable can also be used in the image recipe to
specify the root by UUID using:
SYSLINUX_ROOT = "root=PARTUUID=${DISK_SIGNATURE}-02"
Specifying the root by UUID allows the kernel to locate the root
filesystem even if the device name changes (e.g. /dev/hda2, /dev/hdb2 or
/dev/sdb2 instead of /dev/sda2) due to differences in hardware
configuration.
