I added three new glossary entries for how the build process
figures out the image size. Entries are for IMAGE_ROOTFS_SIZE,
IMAGE_OVERHEAD_FACTOR, and IMAGE_ROOTFS_EXTRA_SPACE.
I still need to create a usage section for this topic.

I created a new section in the "Technical Details" chapter of
the YP Reference Manual to deal with licensing. I migrated the
existing section on tracking licenses from the "Extending YP"
chapter into this section. The new section now includes that info
as well as the new information here.

Richard reviewed the new sections and had a couple comments. There
was one technical error and he also wanted YP worked out when it was
being used in the context of the code that was doing the work here.
So I replaced with more generic terms or specifically called out
BitBake as the responsible software.

I added more information about how BitBake actually runs a task.
The information has to do with how tightly BB controls the execution
environment of the build tasks to prevent contamination from the
build machine from leaking into the task execution environment.
This tight control actually causes some unexpected behavior during
builds. For example, when a user exports and BB_ENV_EXTRAWHITE
an environment item such as CCACHE_DIR, the effects of the environment
item never make it to the BB task execution environment. They only
make it to the data store. The user actually has to take some extra
steps to export that environment item into the task execution environment.
The added information I put into the "Running a Task" section describes
these extra steps.

Long-term strategy for the YP Reference Manual is that it contains
reference material and not "how-to-information". A step in this
direction is to isolate any discussions on components and other
areas of YP that need talked about. So to start with, I have created
a new chapter for now named "Technical Details" that so far has
a discussion of some components and shared state. This is a
step in the direction of making this manual a reference manual and
not a "how to" manual.
Changes included removing redundant material from the 'usingpoky.xml'
chapter and also adding the new chapter 'technical-details' into the
'poky-ref-manual.xml' file used for the make.

There are many references to YP documentation throughout the
YP manual set. They used to have hard-coded links to the
current release (e.g. yoctoproject.org/docs/1.1 for Edison).
This created a situation where if you went to a document on
the website and clicked on a external reference to another
manual, you would redirect to the current manual on the website.
Really, you would want to go to the latest manual, which is
one that is under development. Changing the links to
"yoctoproject.org/docs/latest" makes the tip of master, which
is used for devloping the next release, always have references
to the manuals being developed and not back to the stable
released set of manuals.
This "latest" and "current" scheme for the links is not perfect.
What has to happen when the latest set of the manuals freezes
and becomes the next stable release, all the links in the docs
will need to be changed from "latest" in the URL to the new
release number. So for example, all the "latest" occurences
would need to be changed to "1.2". Then for the next cycle
as development begins again, the links need to be infused with
"latest" again.
