??= is a lazy, conditional assignment. Whereas a ?= immediately assigns to
the variable if the variable has not yet been set, ??= does not apply the
default assignment until the end of the parse. As a result, the final ??= for
a given variable is used, as opposed to the first as in ?=.
Note that the initial implementation relies upon finalise() to apply the
defaults, so a "bitbake -e" without specifying a recipe will not show the
defaults as set by ??=. Moving application of the default into getVar adds
too large a performance hit. We may want to revisit this later.

Better to error as early as possible rather than experience strange behavior
resulting from the use of the largely useless stock bitbake.conf/base.bbclass.

Do not attempt to open the file in the resolve_file method
(a lot like bb.which... maybe bb.which can be used). This way
we don't need to open/close a file which we have already parsed.

Evaluate the statements after having parsed one file. This is
referred to as "entwirren" and we can remove the direct evaluation
and postpone a bit, in the future we can use a cached copy instead
of parsing the original.

When parsing we will collect a number of statements
that can be evaluated...The plan is to be evaluate
things twice (old+new) and then compare the result,
it should be the same.

With obtain it was possible to use an existing fetcher to
download a bb or config file. In practive no one has used it
and it was likely broken in regard to depends_cache... Remove
it for now, simplfiy the code.

* File licence headers were sanitised causing most of the diff.
* cooker.py was created from bin/bitbake.
* cvs fetcher port option was added
* The -f force option was fixed to work correctly
* Multiple entries in rrecrdeps are now handled correctly
(allows adding do_deploy to image depends)
