Okay, I fixed a few bugs in that, and added a second patch.
What's that for? Let's ask bitbake -e:
#

# /home/seebs/poky/meta/conf/abi_version.conf
# conf/site.conf

# conf/local.conf

# conf/target/INVALID-oe-linux.conf
# /home/seebs/poky/meta/conf/machine/qemux86-64.conf includes:

# /home/seebs/poky/meta/conf/machine/include/qemu.inc
# conf/machine-sdk/${SDKMACHINE}.conf
# /home/seebs/poky/meta-yocto/conf/distro/poky.conf
I am not at all sure that this is done correctly, but it passes obvious
sanity checks.
Would appreciate feedback/comments on these, I plan to clean them
up as pull requests eventually.

data_smart.py: Provide (optional) logging of variable modifications
This is very preliminary, and probably not very good, but it
provides a much-wanted feature: An explanation of how variables
got their current values.
How it works:
1. We create a history dict in the data_smart object, the
members of which are lists of tuples. It's three, count them,
THREE unrelated data types in a single object!
2. There is an eventLog(...) function which allows recording
things which happen to variables.
3. All over the place, tons of setVar and related functions
are updated with two optional arguments, filename and lineno.
4. We log pretty much everything if logging is enabled.
5. You can query the history of a thing with data.getHistory(var)
Tracking must be specifically turned on. If it's not, the
history object is a single empty table (cheap) and the calls
to eventLog() and extra argument passing are also probably
quite cheap. As a proof of concept, the showEnvironment function
used by bitbake -e now uses this if available.

data_smart.py: Track configuration file inclusions

meaningless. It could probably be updated to, say, distinguish between
includes and requires. Output is added to bitbake -e.
