bitbake: data.py: Add a warning when expandKeys overwrites an existing key

When two variables are defined as:

${var} = "bar"
foo = "foobar"

The value of 'foo' when ${var} == foo becomes indeterminate.  We
want to warn a user when this situation has been encountered so they
can take corrective actions.

In the above example usually foo == bar, unless multilibs are enabled.
Then ml-foo = "ml-foobar".

Additional information added to the end of the
"Build History Package Information" section."

Buildhistory now collects information on SRCREV values for recipes
fetched from a version control system e.g. Git; additionally a
buildhistory-collect-srcrevs tool is provided to gather this and
convert it to a format suitable for inclusion in global configuration.
Add information on these new features to the appropriate section.

ref-manual, dev-manual, bsp-guide: Applied Paul Eggleton Build history patch 4 of 5.

* BBFILES should be appended to with +=

* BBPATH should be appended to with .=

* Immediate expansion is not necessary for BBFILE_PRIORITY

* Immediate expansion is not necessary for references in layer.conf
  to LAYERDIR since these are automatically expanded at the end of
  parsing the file (and have been for some time).

* Add collection name override to BBFILE_PRIORITY example

* Fix comments referring to old structure ("packages directory" or
  "recipes directory")
