Scott Rifenbark 4597d2a39d adt-manual: Fixed example bitbake command.
The command said 'bitbake image....' where it would be better
to say 'bitbake <image>...'

Scott Rifenbark ef627f855d yocto-project-qs, ref-manual: Fixed core number defaults
Fixes [YOCTO #2528]

The defaults for BB_NUMBER_THREADS and PARALLEL_MAKE are now
automatically set to the build host's number of processor cores.
I updated the "Building and Image" section in the Quick Start
to state that.  I also updated the PARALLEL_MAKE variable.

Scott Rifenbark 32890f29af adt-manual, ref-manual: Cross-toolchain details added. New class also.
In the adt-manual in the "Optionally Building a Toolchain Installer"
setion, I added some basic advantage information for building a
toolchain installer using bitbake image -c populate_sdk.

In the ref-manual, I added cross-referencing to this basic information
in several strategic areas: "SDK Generation", the populate_sdk class
reference section, the populate_sdk_* class reference section, and the
"Cross-Development Toolchain Generation" sections.

Finally, I also put in documentation for a new class called
autotools-brokensep.

Fixes [YOCTO #2424]

Some imgage names were cleaned up to have more meaningful names.
These doc changes here take care of changing "core-image-basic"
to "core-image-full-cmdline".

Five instances changed.

Scott Rifenbark 7a5cd2123a ref-manual, mega-manual: Added manifest file information
Fixes [YOCTO #5410]

I updated the figure that shows what do_rootfs does to create
the image.  The new addition is the creation of the .manifest file
that lists out package information in the image.  Supporting text
was also added in the section.

The updated figure was needed in both the ref-manual and
mega-manual figures folders.

Also, part of the fix included a new variable description for the
IMAGE_MANIFEST variable.

example does it by hand.

Also, in the menuconfig example.  I updated the kernel version from
3.4 to 3.14.  It was very old.

Scott Rifenbark 02fa765b8e adt-manual: Added a link to BitBake term and fixed some formatting.
Needed a link to the term "BitBake".  Also, reformatted the
occurrences of "BitBake command" into "<filename>bitbake</filename>
command as they are actual command references.

Scott Rifenbark 720cdabe9b adt-manual: Edited the "Perf" bullet item.
The link to the wiki had some extra instruction in there that
was bogus.  I removed that.

Scott Rifenbark 2edf033741 adt-manual: Restructured opening organization.
The start of this manual was odd.  I created a new "Introduction"
chapter and inserted it into the build file (adt-manual.xml).
This new chapter introduces the manual.  That left the remainder
of the original first chapter to be able to focus on what it
really needed to talk about and that is the ADT.  It is a better
organization.
