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".

This patch adds tracking of the history of variable assignments.
The changes are predominantly localized to data_smart.py and
parse/ast.py. cooker.py and data.py are altered to display the
recorded data, and turn tracking on for the bitbake -e case.
The data.py update_data() function warns DataSmart.finalize()
to report the caller one further back up the tree.
In general, d.setVar() does what it used to do. Optionally,
arguments describing an operation may be appended; if none
are present, the operation is implicitly ignored. If it's
not ignored, it will attempt to infer missing information
(name of variable, value assigned, file and line) by examining
the traceback. This slightly elaborate process eliminates a
category of problems in which the 'var' member of the keyword
arguments dict is set, and a positional argument corresponding
to 'var' is also set. It also makes calling much simpler for
the common cases.
The resulting output gives you a pretty good picture of what
values got set, and how they got set.
RP Modifications:
a) Split from IncludeHistory to separate VariableHistory
b) Add dedicated copy function instead of deepcopy
c) Use COW for variables dict
d) Remove 'value' loginfo value and just use 'details'
e) Desensitise code for calling order (set 'op' before/after
infer_caller_details was error prone)
f) Fix bug where ?= "" wasn't shown correctly
g) Log more set operations as some variables mysteriously acquired
values previously
h) Standardise infer_caller_details to be triggered from .record()
where at all possible to reduce overhead in non-enabled cases
i) Rename variable parameter names to match inference code
j) Add VariableHistory emit() function to match IncludeHistory
k) Fix handling of appendVar, prependVar and matching flag ops
l) Use ignored=True to stop logging further events where appropriate

Currently, calling a shell function using exec_func may result in
dependent functions being missing, if the shell parser can't detect
the dependency, even if it was specified with the vardeps flag.
This patch ensures the function looks at the flag and considers it
when deciding which other functions need to be output.

The inherits cache contains duplicate entries, some with the full patch, some
just starting classes/xxx. This is a waste of parse time and potentially
error prone. This patch fixes various pieces of code so the absolute paths are
always preferred and work correctly. The inherits_class function did not work
with full paths so the patch fixes this.

Instead of logging the function/variable separately as a NOTE when
failing to expand, re-raise ExpansionError with more contextual
information. This means that the full details are reported in Hob as
well as actually reporting the original error message in any UI where
we previously did not. For example, we used to get this with tab/space
indentation issues in a python function:
NOTE: Error expanding variable populate_packages
ERROR: Unable to parse /path/to/recipename.bb
Now, we will get this:
ERROR: ExpansionError during parsing /path/to/recipename.bb: Failure
expanding variable populate_packages: IndentationError: unindent does
not match any outer indentation level (<string>, line 4)

Mixed spacing in python functions can cause subtle issues and
generally confuses users. We've standardised on 4 space indentation,
adding this warning helps ensure consistency and avoid bugs. It
also makes _prepend and _append operations on python functions slightly
less risky.

Add a dependency to each variable on a filtered list of its varflags.
This is intended to catch things such as SRC_URI checksums, varflags
controlling extra functionality from classes (e.g. the recently updated
update-alternatives class in OE-Core), etc. and ensure their values
influence the sstate checksums.
There is an exclusion list which needs to be set via bitbake.conf
(BB_SIGNATURE_EXCLUDE_FLAGS), if this is not set then the functionality
is disabled. The existing vardepsexclude mechanism can also be used to
exclude undesired varflags, but they must be fully specified, e.g.:
do_patch[vardepsexclude] += "do_patch[someflag]"
Implements [YOCTO #2517].

We have a problem if we want to inject specific information into the variable
dependency code. There are cases for example where we want a dependency
on the value of X but it doesn't matter how X was constructed or what
dependencies it might have had, we only care about the absolute value.
With the current code, its near enough impossible to do this.
This patch adds such a mechanism so the user can trigger this with code like:
baselib[vardepvalue] = "${baselib}"
It also refactors some of the code so we do variable lookups once
instead of doing this in two different functions.

- Tweak the warning messages slightly (they had to be altered anyway to
inject the variable being parsed).

The recent change which modified inheritFromOS to use the intial
environment, rather than the current environment, introduced a bug such
that variables which had been cleaned from the environment where still set
in the data store.
This patch changes things such that a list of approved environment
variables is saved after the environment is cleaned and only the variables
in this list are inherited in inheritFromOS.

Currently, anything whitelisted in the environment makes it into the worker
processes. This is undesireable and the worker environment should be as
clean as possible. This patch adapts bitbake sosme variables are loaded into
bitbake's datastore but not exported by default. Any variable can be exported
by setting its export flag.
Currently, this code only finalises the environment in he worker as doing so
in the server means variables are unavailable in the worker. If we switch
back to fork() calls instead of exec() this code will need revisting.
