This section was largely redundant now. The small things that did
add value I placed in other areas of the chapter 2. One was a new
section on expanding variables using bitbake -e. Another was a bit
about the defconfig file. And a small procedure on how to create
config fragments using the "diffconfig" command was retained.
Links from the dev-manual and the ref-manual were adjusted as well.

Fixes [YOCTO #11630]
The section on the devtool workflow in the dev-manual was 99%
identical to what was in the sdk-manual. I have moved the
workflow procedure from the old "Model" chapter of the dev-manual
to be merged with what was in the sdk-manual. In truth, the
only things added were a note about devtool not being exclusive
to SDK development.
The result of moving (deleting) this section was that the "model"
chapter of the dev-manual went away. The devtool stuff, Quilt,
devshell, and python shell are all out now and there is no
chapter left. So, mega-manual had to be adjusted to not pull that
chapter in when building the dev-manual. I had to delete three
figures that were used in the flow. The figures were already
replicated in the sdk-manual. The figures were deleted from the
figures folder of both the dev-manual and the mega-manual.
I had to make sure all references to the old devtool stuf in the
YP doc set were adjusted.
