dtoc: Support packing the device tree
After any node/property deletion the device tree can be packed to remove
spare space. Add a way to perform this operation.
Note that for fdt_fallback, fdtput automatically packs the device tree after
deletion, so no action is required here.

cmd: fdt: add fdt overlay application subcommand
The device tree overlays are a good way to deal with user-modifyable
boards or boards with some kind of an expansion mechanism where we can
easily plug new board in (like the BBB or the raspberry pi).
However, so far, the usual mechanism to deal with it was to have in Linux
some driver detecting the expansion boards plugged in and then request
these overlays using the firmware interface.
That works in most cases, but in some cases, you might want to have the
overlays applied before the userspace comes in. Either because the new
board requires some kind of an early initialization, or because your root
filesystem is accessed through that expansion board.
The easiest solution in such a case is to simply have the component before
Linux applying that overlay, removing all these drawbacks.

libfdt: Add overlay application function
The device tree overlays are a good way to deal with user-modifyable
boards or boards with some kind of an expansion mechanism where we can
easily plug new board in (like the BBB, the Raspberry Pi or the CHIP).
Add a new function to merge overlays with a base device tree.
