ref-manual, dev-manual: Updates to support recipe-specific sysroots

Browse Source 
Changes covered several areas.  Version 2.3 of the YP now supports
recipe-specific sysroots and is not limited to machine-specific
as was prior releases.  Manual changes were as follows:

dev-manual: "Sharing Files Between Recipes" - Wordings were changed
to support the new functionality.

ref-manual: do_prepare_recipe_sysroot task added to the list of
tasks described in "Configuration and Compilation".

ref-manual: Extensive re-write of the "staging.bbclass" section.

ref-manual: Added a section to the build structure for
build/tmp/work/tunearch/recipename/version/.  This section breaks
down the recipe-specific subdirectories used to create (stage)
the sysroot.

ref-manual: New section (entry) for the do_prepare_recipe_sysroot
task in the task chapter.

ref-manual: Added a variable glossary description for the
SSTATE_SCAN_FILES variable.

In addition to these changes, I sprinkled in a liberal amount
of cross-referencing for the readers pleasure.

Controls the list of files the OpenEmbedded build system
scans for hardcoded installation paths.
</para>
<para>
During a build, the OpenEmbedded build system creates a
shared state (sstate) object during the first stage of
preparing the sysroots.
During the build, the object is scanned for hardcoded paths
for original installation locations.
The list of files that are scanned for paths is controlled
by the <filename>SSTATE_SCAN_FILES</filename> variable.
