This patch tries to make a union mount in live image. For example,
if aufs is enabled with the aufs-enable.scc configuration fragment,
the init-live.sh script will use aufs to make a union mount.
Although overlayfs is not supported by Yocto kernel yet, this patch
still takes it into consideration with the expect that the related
code should at least serve as a placeholder.

When boot media has been found, udev will be killed. If udev is busy
to mount other medias at the killing time (especially medias is many),
the above issue will occur occasionally.
Invoke `udevadm settle' before killing udev will resolve this
issue, it watches the udev event queue, and exits if all current
events are handled.
Use variable `_UDEV_DAEMON' to replace hardcoded `udevd' to keep
consistent with previous.

1, This issue happens to BSP only.
After a BSP board is booted with Yocto linux from USB drive, "cat /proc/mounts" shows:
...
/dev/sda3 /media/sda3 ext3 rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered 0 0
/dev/sda1 /media/sda1 ext3 rw,relatime,errors=continue,barrier=1,data=ordered 0 0
/dev/sda2 /media/sda2 ext3 rw,relatime,errors=continue,user_xattr,acl,barrier=1,data=ordered 0 0
...
but actually the directory /media/sda1 doesn't exist at all, "df" shows:
...
df: /media/sda3: No such file or directory
df: /media/sda1: No such file or directory
df: /media/sda2: No such file or directory
...
2, This is because the mount data comes from proc setup during early boot
before the change root, which then uses a different root filesystem, the
media is not in the new root filesystem.
3, During early boot before switch_root, use `mount --move' to move all
medias to the new root filesystem could also fix this issue.

This was not the correct fix for this issues, it turns out that
base-files package was getting installed un-intentionally when
rpm-postinsts was split out. The base-files recipe lays down the
link that caused the cat failure.

The install boot option was giving the following error when one tried to
install the live image on a permanent storage of a BSP.
cat: write error Invalid argument
Installation image failed
sh: can't access tty: job control turned off
Further digging into the issue, found out that the install script was trying
to do this:
cat /proc/mounts > /etc/mtab
And in the base-files recipe the /etc/mtab is made soft link to /proc/mounts.
So the cat command was failing to write on /etc/mtab. As the contents of
the /proc/mounts is already reflected in the /etc/mtab file due to the
symlink-ing, there is no need for this step to recreate /etc/mtab in the
install script. So just removing this unnecessary step, which solves the
install issue of the live images.
Fixes this bug:

/etc/udev/scripts/mount.sh is removed by init-install.sh, but the udev
rules file which specifies the invocation of this script is not removed,
thus causing the error message '/etc/udev/scripts/mount.sh: No such file
or directory' shown at a live install.
The /etc/udev/rules/automount.rules no longer works once the mount.sh script
is removed. So we remove it to avoid the error message.

Fixes [YOCTO #3870] atom-pc - cannot boot image on netbook after install
The problem here is that grub2 is installed but a grub 1 menu.lst is
created at install time. At boot, grub2 doesn't find a grub.cfg file and
drops to the grub shell.
This happens because the installer is looking for 40_custom (a grub2
file) on the rootfs, but grub2 isn't installed on the rootfs. It exists
in the initramfs. Patching the installer to look on the initramfs
resolves the problem.
Note that the problem may have occurred if grub2 used to be installed on
the rootfs but was later removed. In any case, the installer is HORRIBLE
and really needs to be completely redesigned as part of the deployment
effort. For now, this should get the live image installer limping along
again.
Tested on a Toshiba NB-305.

In cases where other initramfs modules need to rely on
udev running (ie in my case I have to load firmware on
a device that is slow to start) there needs to be a way
to keep it running during the lifecycle of the initramfs
but still be shut down before swith_root is called. I
added a module_pre_hook that will shut down udev before
the finish module is called.

Previously, the /media/xxx which contains the root image was not
moved to be under the real root filesystem. Because of this, the
output of the 'mount' command is somewhat confusing, that is, it
has some mount point that is not even in the filesystem.
Besides, on some machine, it caused the recovery procedure when we
booted it next time.
This patches fixes this issue by moving the /media/xxx over to be
under the real root filesystem.

[YOCTO #1919]
Create a basic EFI installer script modeled after the existing installer
and add it to a new initramfs-live-install-efi recipe. Update the
init-live.sh script to distinguish between LABEL=install and
LABEL=install-efi and select the appropriate script. Add the efi
installer to core-image-minimal-initramfs.
Update grub-efi.bbclass to use "LABEL=install-efi" when it detects a
label of "install". This is clearly not ideal, but a proper fix would
involve decoupling the LABELS assignment from the image-live.bbclass
usage of SYSLINUX_LABELS. We should be able to address that in a
follow-on clean-up series.

The current partitioning scheme leaves a 1MB gap between all the
generated partitions by adding a 1 to the end of the last partition to
use as the start of the next. parted is smart enough to not overlap
start and end positions of the same value. This avoids the 1 MB gaps.
Rather than pad the disk with 1MB in the beginning and cut it off at the
MB boundary on the end, we can use 0% and 100% to allow parted to do the
required math and use as much of the disk as possible.

Fixes [YOCTO #2385]
The installer only searches for hd[ab] sd[ab]. Some newer BSPs have mmcblk
devices that should be used as the install target. These devices also have a
partition prefix (mmcblk0p1 instead of mmcblk01). As they are detected
asynchronously, it is necessary to add the rootwait kernel parameter to avoid
a race condition trying to mount the root device.
As BSPs like the FRI2 and the sys940x have mmc devices and will have a 1.2
release, we should push this to 1.2.1. The changes are perfectly contained and
easily verified.
Test for an mmcblk device and add the p partition prefix if necessary. Add the
rootwait kernel parameter when an mmcblk device is detected. Replace the series
of explicit umount commands with a single umount using a wildcard. This will
find all the partitions and will not try to unmount non-existant devices. Avoid
copy and paste errors by replacing /dev/${device}${pX} references with the
previously assigned rootfs, bootfs, and swap variables.
These changes have been tested on the FRI2 Sato image which installed to
/dev/mmcblk0 as well as the N450 Sato image which installed to /dev/sda. Both
were successful.

The existing PACKAGE_ARCH = "all" mechanism of sharing packages is problematic
with sstate since there are a variety of variables which have target specific
values and the sstate package therefore correctly changes signature depending
on the MACHINE setting.
This patch creates a new "allarch" class which sets:
PACKAGE_ARCH = "all"
(as per the existing convention)
INHIBIT_DEFAULT_DEPS = "1"
(since its not target specific and therefore can't depend on the cross
compiler or target libc)
TARGET_ARCH = "all"
TARGET_OS = "linux"
TARGET_CC_ARCH = "none"
(since these variables shouldn't change between the different packages and
target compiler flags shouldn't be getting used)
PACKAGE_EXTRA_ARCHS = ""
(since we shouldn't be depending on any architecture specific package architectures)
Not all PACKAGE_ARCH = "all" recipes can use this class since some run configure
checks on the compiler. This means they have target specific components and therefore
the "all" classification is incorrect.

Fixes [BUGID #693]
The init-live.sh script starts udevd in init-live.sh:early_setup(),
but doesn't account for the possibility that the root device may have
already been registered by the kernel before udevd starts up.
If the device is detected after udevd starts up, everything's fine -
udevd gets the 'add' uevent for the device, the root image shows up at
e.g. /media/sda/rootfs.img, and the boot continues.
If however the device is detected before udevd starts up, udevd misses
the 'add' uevent and the root image never shows up, causing it to stay
in the 'waiting for removable media' loop forever.
The 'udevadm trigger' command is meant to be used to avoid this
situation, but init-live.sh doesn't use it. Furthermore, since the
default was changed in udev 152 from 'add' to 'change', the command
needs to explicity name 'add' as the action.
