Sometimes, when a value changes in the buildhistory it is useful to
know when a related (but not necessarily itself monitored) value
changes as it can help explain the change. For example, when the list
of installed packages for an image changes it could be caused by a
change to one of the image-related variables.
Related field changes are recorded as sub-items of each change.
Currently the only way to visualise these is via the buildhistory-diff
tool, so an example would be:
Changes to images/qemux86/eglibc/core-image-minimal (installed-package-names.txt):
locale-base-de-de was added
procps was added
* IMAGE_LINGUAS: added "de-de"
* IMAGE_INSTALL: added "procps"
Here we see that two additional packages have been added to the image,
and looking at the related changes to the two variables IMAGE_INSTALL
and IMAGE_LINGUAS we have the explanation as to why.

Avoid errors when comparing changes for KEY = value files (package info
files and image-info.txt):
* Handle keys appearing and disappearing - this will help to handle PE
in package info files (which is only written when it is not blank) and
when we add additional fields in future.
* Handle when old value is 0 for numeric field (avoid division by zero)
* Report when numeric field was empty or missing rather than 0 (but
still treat it as 0 for comparison purposes)

Don't specify any argument to the split() function when handling changes
to list type variables (e.g. PACKAGES) so that the values are split by
any whitespace and only split once for a block of multiple whitespace
characters.

Record some additional information about images - the uncompressed size
of the final image as well as the values of various variables that may
have influenced its contents. This is recorded in a machine-readable
"image-info.txt" file similar in structure to the package history files.
Also add some code to analyse changes to these values. (Most of the
variable values aren't monitored directly but will be used as contextual
information when they change at the same time as the content of the
image changing.)

Adds a buildhistory-diff script which can be used to analyse changes in
the buildhistory git repository (as produced by buildhistory.bbclass),
and report significant ones that may need manual checking to ensure they
aren't regressions (e.g. package size changed by more than a certain
percentage, files added/removed/changed in the image, etc.)
The implementation is actually split into a small script and a Python
module, in order to make the logic re-usable in a future web-based
interface.
Implements the first part of [YOCTO #1566].
