Allows the heavy finalise function to only be run for the case we're
interested in when running tasks, saving some processing time.

Currently, if a variable has been set with ??= and the code looks it up
before the data finalisation phase, no value is found. This is causes
serious problems for anonymous python functions which manipulate data, or
for the fetcher revision handling code where revisions can be set with
??=.
There is also a significant performance implication for processing lazy
assignment in finalise.
Moving the check for a default value into getVarFlag addresses both
the timing issue and the performace. This change gives a 7% real time
performance improvement to parsing the Poky metadata. The cost of the
check at this point is minimal since we have all the data flags available.
This should also fix Yocto bug 752.

We will be needing this information to improve the tracebacks of python code
from the metadata, as well as to give the user information about where
variables were defined, so they know how it ended up the way it is.

We use a custom Logger subclass for our loggers
This logger provides:
- 'debug' method which accepts a debug level
- 'plain' method which bypasses log formatting
- 'verbose' method which is more detail than info, but less than debug

These functions allow generation of dependency data between funcitons and
variables allowing moves to be made towards generating checksums and allowing
use of the dependency information in other parts of bitbake.

The methodpool, ${@} expansions, anonymous python functions, event handlers
now all run with the same global context, ensuring a consistent environment
for them. Added a bb.utils.better_eval function which does an eval() with the
same globals as better_exec.

This implements a feature similar to BBCLASSEXTEND, but for generating
multiple versions of a given recipe. For example: BBVERSIONS = "1.0 2.0 git".
In addition to the above, one can utilize [a-b] style patterns, and can have a
:<basever> postfix, which allows you to essentially name the range of
versions. Both the current version and the basever end up in OVERRIDES, and
the basever gets placed into the BPV variable. The default BPV, if none is
specified, is the original PV of the recipe, before bbversions processing.
In this way, you can do things like:
BBVERSIONS = "1.0.[0-6]:1.0.0+
1.0.[7-9]:1.0.7+"
SRC_URI_append_1.0.7+ = "file://some_extra_patch.patch;patch=1"
Or you can create a recipe per range, and name the recipe file as such: nano_1.0.7+.bb.

??= 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.

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.
