Add KERNEL_IMAGETYPES to support building packaging and installing
multi types of kernel images, such as zImage uImage, at one time.
KERNEL_IMAGETYPE and KERNEL_ALT_IMAGETYPE work as before.

This works around a limitation of the chkconfig update-alternatives, so it
works with all our update-alternatives providers.

Pull out the compilation of the DTB blobs right after the kernel's
own do_compile function finishes. This makes them available just in
time for the kernel image construction functions.

| ARM: dt: change .dtb build rules to build in dts directory
|
| The current rules have the .dtb files build in a different directory
| from the .dts files. The only reason for this is that it was what
| PowerPC has done historically. This patch changes ARM to use the generic
| dtb rule which builds .dtb files in the same directory as the source .dts.

As the Linux kernel, unconditionally, builds the dtc application and
it is the compatible version with the DeviceTree files shipped within
the kernel it is better to use it and the kernel build system to
generate the dtb files.
Some DeviceTree files rely on CPP and kernel headers to be able to
generate the dtb binary contents and it is harder to replicate it
outside of Linux kernel build system so we /use/ it.
To comply with these assumptions we need to use the dtb file when
calling 'make' instead of pointing to the DeviceTree source file; the
code has been made backward compatible but it is advised to move to
the new definition to avoid warnings as:
,----[ Original definition ]
| KERNEL_DEVICETREE = "${S}/arch/arm/boot/dts/imx6q-sabresd.dts"
`----
Becomes:
,----[ New definition ]
| KERNEL_DEVICETREE = "imx6q-sabresd.dtb"

Devicetree files were installed hard-coded in /boot. When KERNEL_IMAGEDEST
is anything else but "boot", the postinstall script and the file locations
no longer match and the postinstall will fail.
Replace "boot" with "${KERNEL_IMAGEDEST}" to fix this problem, and to allow
the devicetree files to be installed in another location.

* This is similar to the symlinks provided for the kernel image
in the /boot directory of a file system. The goal is to have
simply named symlinks in /boot that mirror the device tree
name in the kernel sources. This is so that programs like
U-Boot can easily find the default device tree binary in the
/boot directory and use that when booting the kernel.
* Use update-alternatives to handle proper creation and removal
of the symlinks.

The bb and os modules are always imported so having these extra import calls
are a waste of space/execution time. They also set a bad example for people
copy and pasting code so clean them up.

The dtb files were not being installed into a location compatible with sstate and
the do_deploy task. This means in builds just using sstate, the dtb files disappeared.
This patch fixes the code to use the correct location for deploy files.

Using "1" with getVar is bad coding style and "True" is preferred.
This patch is a sed over the meta directory of the form:
sed \
-e 's:\(\.getVar([^,()]*, \)1 *):\1True):g' \
-e 's:\(\.getVarFlag([^,()]*, [^,()]*, \)1 *):\1True):g' \
-i `grep -ril getVar *`

This is the result of running the following over the metadata:
sed \
-e 's:bb.data.\(setVar([^,()]*,[^,()]*\), *\([^ )]*\) *):\2.\1):g' \
-e 's:bb.data.\(setVarFlag([^,()]*,[^,()]*,[^,()]*\), *\([^) ]*\) *):\2.\1):g' \

Fixes [BUGID #610]
The powerpc linux-yocto kernels were not creating dtb images
in the deploy directories. This was due to two problems:
- the dtb generation rules were not being configured
- the boards were not specifying a device tree in their config
This change addresses the first point by factoring out the
dtb generation routines into a new include that can be used by
multiple recipes.
